'''Shieldstun''' is an inactionable period that occurs when a character's [[shield]] is hit. It is comparable to [[hitstun]], in that it occurs after [[hitlag]] and only for the defending character. While the attacker still experiences the hitlag of the move, they do not undergo shieldstun, allowing them to move again before their opponent can if the ending [[lag]] of the attack is low. During the period of shieldstun, the shielding player cannot perform any of their normal [[out of shield]] options, rendering them stuck. Many multiple-hit moves that hit rapidly (such as [[Fox]]'s or [[Yoshi]]'s [[down aerial]]s) hit fast enough to keep an opponent in shieldstun for the duration of the move, as each hit lands while the opponent is still in shieldstun from the previous hit. In addition to not being able to perform out of shield options, players in shield stun cannot release the shield, adjust the tilt of their shield, [[shield drop]], or change their shield's density. Attempting to perform any of these actions while in shieldstun will have them happen the frame shieldstun ends instead. 

With the inability to jump, [[grab]], roll, or spot dodge out of their shield, the player in shieldstun is very susceptible to another hit or a grab. Though it is rare, this can sometimes be used to the point of breaking a player's shield, as with {{SSBM|Fox}}'s and {{SSBM|Falco}}'s [[pillaring]] [[combo]]s. A combo meant to lock an opponent in shield until their shield breaks is known as a [[shield break combo]]. However, outside of ''SSB'', these combos are not perfect, as all other combos on shield have gaps in shieldstun. Thus, the goal of shield combos in ''Melee'' is rarely to outright break shields: it is far more likely an attempt at causing a [[shield poke]], or to [[bait]] and [[punish]] a roll, grab, or spot dodge. Still, since gaps in shieldstun must exist it is necessary to mixup where and for how long these gaps fall. Doing so covers different out of shield options that the defending player might want to use. As an example, a [[double shine]] covers the grab-sized gap that is normally left after a [[waveshine]] or a jump out of [[shine]] into an [[aerial]], and grants the attacker the hit they were looking for. 

==In ''[[Super Smash Bros.]]''==
In ''SSB'', shieldstun is extremely high. When hit on shield, the majority of moves leave the defending player in such a long period of shieldstun, that another hit is nearly always guaranteed. This is especially apart with aerials with the use of [[Z-cancel]]ling. This, along with the lack of [[perfect shield]]ing, makes shield break combos easier and far more frequent. Some moves, such as {{SSB|Kirby}}'s [[up tilt]], are notorious for breaking shields on their own with repeated use. The formula for frames of shieldstun in ''SSB'' is <code>d * 1.62 + 4</code> (rounded down), where '''d''' is the amount of [[damage]] the attack would deal if it was unshielded ([[shield damage]] dealt by the move is not factored into this formula). In the Japanese version, the shieldstun formula was different, with the formula being <code>d * 1.75 + 3</code> (rounded up). This meant that most attacks dealt even more shieldstun, unless they dealt 1%, 2%, 4% or 5%.

==In ''[[Super Smash Bros. Melee]]''==
In ''Melee'', shieldstun duration in general was reduced. A large difference to other Smash games is the introduction of analog shielding. The analog shield level used when blocking affects shieldstun: the lighter the shield, the more shieldstun the blocker suffers. The formula for frames of shieldstun in ''Melee'' is <code>200 / 201 * ({[d * (a + 0.3)] * 1.5} + 2)</code> rounded down, where '''d''' is the amount of [[damage]] the attack would deal if it was unshielded, rounded down (shield damage dealt by the move is not factored into this formula), and '''a''' is <code>0.65 * {1 - [(s - 0.3) / 0.7]}</code>, where '''s''' describes the analog shield level used. Fully depressed trigger corresponds with <code>s = 1.0</code>, while the lightest possible analog press that still yields shield has <code>s = 0.30714</code>.<ref>https://smashboards.com/threads/official-ask-anyone-frame-things-thread.313889/page-28#post-20577303</ref> This amount of shieldstun, while heavily reduced, is still sufficient to leave smart and quick attackers at an advantage. Many moves are unsafe on shield, and it is possible for defending players to capitalize on such hits. But many moves, especially certain aerials, are still safe. Pressuring an opponent's shield is challenging and risky, but highly rewarding. Often, despite a move merely breaking even on shield, or even being a few frames negative, the attacker will still have an advantage. Options out of shield, especially movement, are so limited that good spacing or quick [[dash dancing]] out of lag allow the attacker to safely pressure despite frame disadvantage.

It is possible to shield buffer some evasive options out of shield in ''Melee'' by holding the C-stick while in shieldstun. The character will then jump (if held upwards), spot dodge (if held downwards) or roll (if held sideways) on the first frame after they leave shieldstun.

{{SSBM|Yoshi}} is a notable exception to this rule. While he cannot jump out of shield in this iteration, he suffers no shieldstun whatsoever, which, combined with the other unique properties of his shield, give his shield game a very different dynamic to the rest of the cast.

==In ''[[Super Smash Bros. Brawl]]''==
In ''Brawl'', shieldstun was further reduced. Very few attacks on shield are safe. Combined with the lowered time to drop shield (taking 7 frames instead of 15), this means that hitting shields in ''Brawl'' puts attackers in a very vulnerable position. The approximate formula for frames of shieldstun in ''Brawl'' is <code>d * 0.375</code> rounded down (shield damage dealt by the move is not factored into this formula).

==In ''[[Super Smash Bros. 4]]''==
In ''Smash 4'', shieldstun was originally thought to have been reduced again from ''Brawl'', but further testing showed this to be false. The working formula for shieldstun duration in ''Smash 4'' prior to patch [[1.1.1]] was originally <code>d * 0.39</code> rounded down (bonus [[shield damage]] dealt by the move is not factored into the formula), which results in barely higher shieldstun compared to ''Brawl'' [http://smashboards.com/threads/mechanics-techniques-discussion.368206/page-40].

However, following patch [[1.1.1]], shieldstun from [[Specials: Direct|direct]] attacks was increased dramatically, to the point of being higher than in ''Melee''. The new formula is <code>d * 0.58 + 2</code> rounded down, and for [[indirect]] attacks (such as [[projectile]]s), the formula is now <code>d * 0.29 + 2</code>. [[Powershield]]ing further multiplies the amount of shieldstun by 0.66, so, for versions 1.1.1 and later, the formula is <code>d * 0.3828 + 2</code> for direct attacks and <code>d * 0.1914 + 2</code> for indirect attacks when the attack is powershielded.

Version [[1.1.3]] of the game [https://twitter.com/Ruben_dal/status/990306476219666432 added] an additional wrinkle to shieldstun: if a character is trapped in shieldstun for 10 hits, they are allowed to cancel it with a [[roll]] or [[spot dodge]], and the [[intangibility]] of either option comes out immediately on frame 1, regardless of their coded startup. Practically, there are very few moves that can hit a shield enough times for this to trigger; the looping hit of a charging [[Aura Sphere]] is the most noticeable. In the case of said move, this mechanic allows shielding characters to escape it if they are trapped by it at the ledge, where they would otherwise be forced to [[shield SDI]] or have their shield broken.

==In ''[[Super Smash Bros. Ultimate]]''==
Shieldstun has been adjusted further in ''Ultimate'', with the new formula being <code>d * 0.8 * m + 2</code>, rounded down<ref>https://twitter.com/BenArthur_7/status/1073252767496617986</ref>. '''d''' is the amount of damage the attack would deal if unshielded (without counting shield damage), while '''m''' is a multiplier that depends on the type of attack used:
*[[Smash attack]]s use a multiplier of 0.725, effectively resulting in the same 0.58 multiplier from ''Smash 4''.<ref>https://twitter.com/BenArthur_7/status/1079237233192910849</ref>
*[[Aerial attack]]s use a multiplier of 0.33, with the exception of [[grab aerial]]s and landing hitboxes, resulting in an overall multiplier of 0.264.
*Indirect attacks (such as [[projectile]]s) use a multiplier of 0.29, resulting in an overall multiplier of 0.232. For smash and aerial attacks that are also projectiles (such as {{SSBU|Mega Man}}'s [[forward smash]] and [[down aerial]]), only this multiplier applies.
*In other cases, the multiplier is 1 by default. However, specific characters' moves that are not in the above categories can also have their own '''shieldstun multiplier'''. These are mostly employed by [[rapid jab]]s and [[dash attack]]s, which use a higher multiplier than usual to either prevent shielding opponents in range from escaping them or to decrease their [[punish]]ability (respectively), but a few other moves possess them as well, such as {{SSBU|Ridley}}'s [[Skewer]], which uses a lower multiplier than usual to prevent its sweetspot from otherwise producing ludicrously high shieldstun, as its first hit deals 40% damage. Shieldstun multipliers also affect the amount of pushback inflicted on the shielding fighter, further affecting how easy or difficult it is to punish moves out of shield.

As a result, shieldstun remains unchanged for smash attacks compared to ''Smash 4'', but is increased for direct special moves and all other ground attacks; [[tilt attack]]s in particular are noticeably safer on shield. Conversely, it is decreased for aerial attacks and projectiles, most significantly the former. The new 0.85× damage multiplier for aerial attacks performed in a [[short hop]] also further reduces their potential shieldstun. However, due to the universally lower [[landing lag]] in ''Ultimate'', the general safety of aerial attacks on shield remains unchanged, with some of them being slightly safer. Furthermore, shield dropping takes longer (11 frames instead of 7), while [[shield grab]]bing after shieldstun has increased startup by 4 frames, and although the new [[powershield]] mechanics allow characters to retaliate against attacks faster, it is harder to pull off, as it is now triggered by dropping the shield instead of putting it up. Overall, attacking shields in ''Ultimate'' is more favorable, with options to safely punish out of shield being riskier (albeit still highly rewarding), encouraging players to focus more on offense.

The ability to cancel shieldstun with a roll or spot dodge after being locked in it for 10 hits returns from ''Smash 4'', and is now applicable to several other moves, most remarkably every [[rapid jab]], due to their increased shieldstun and much faster hit rate. This renders it vastly more useful in punishing such moves, as in the case of rapid jabs, the shielding character can usually roll behind the attacker, who will then be forced to unleash their rapid jab's finisher and thus become much more vulnerable. This mechanic's larger notoriety has led to it being referred to as '''shieldstun canceling''' by the community.

-'''Shieldstun''' (referred to as '''Downtime from Shielding''' by ''[[Super Smash Bros. Ultimate]]''{{'}}s [[tip]]s and official patch notes) is an inactionable period that occurs when a character's [[shield]] is hit. It is comparable to [[hitstun]], in that it occurs after [[hitlag]] and only for the defending character. While the attacker still experiences the hitlag of the move, they do not undergo shieldstun, allowing them to move again before their opponent can if the ending [[lag]] of the attack is low. During the period of shieldstun, the shielding player cannot perform any of their normal [[out of shield]] options, rendering them stuck. Several fast multi-hitting moves (such as [[Fox]]'s or [[Yoshi]]'s [[down aerial]]s) hit fast enough to keep an opponent in shieldstun for the duration of the move, as each hit lands while the opponent is still in shieldstun from the previous hit; this is usually referred to as a "blockstring", a term stemming from similar situations with block mechanics in traditional fighting games. In addition to not being able to perform out of shield options, players in shield stun cannot release the shield, adjust the tilt of their shield, [[shield drop]], or change their shield's density. Attempting to perform any of these actions while in shieldstun will have them happen the frame shieldstun ends instead.

Compared to the international versions, the Japanese version has even more shieldstun for most attacks, unless they deal 1%, 2%, 4% or 5%, where they deal the same amount of shieldstun.
 ==In ''[[Super Smash Bros. Melee]]''==
-In ''Melee'', shieldstun duration in general was reduced. A large difference from other ''Smash'' games is the introduction of analog shielding. The analog shield level used when blocking affects shieldstun: the lighter the shield, the more shieldstun the blocker suffers. The formula for shieldstun frames in ''Melee'' is <math>{200\div201}\times(((d\times(a+0.3))\times1.5)+2)</math> rounded down, where the values correspond to the following:

-*<math>d</math> is the base [[damage]] of the attack, rounded down. Usually that corresponds to the [[damage]] the attack would deal if not shielded. However, many thrown items deal additional damage on hit based on the speed of the item, and that extra damage doesn't contribute to shieldstun.

While he cannot jump out of shield in this iteration outside digital shield startup, he suffers minimal or no shieldstun, which combined with the other unique properties of his shield, gives his shield game a very different dynamic to the rest of the cast. Yoshi only receives shieldstun when blocking during any of his first 4 shield startup frames, and in those cases suffers an amount of shieldstun equal to <code>5 - shield frame# </code>.

-In ''Brawl'', the formula for shieldstun frames is <math>d\times0.345</math>, rounded down. As a result, shieldstun is even more drastically reduced than in ''Melee'', with attacks that deal less than 2.9% damage inflicting no shieldstun at all. Combined with the lowered time to drop shield (taking 7 frames instead of 15), this puts attackers in a much more vulnerable position for hitting shields. As a result, ''Brawl''{{'}}s metagame is considerably more defensive, with very little in the way of shield pressure, instead putting more emphasis on characters keeping themselves away from shielding opponents, as a [[punish]] is nearly guaranteed otherwise. However, shield pushback is increased compared to ''Melee''{{'}}s fully dense shields, unless the attack is [[perfect shield]]ed, which allows a few powerful and long ranged moves with relatively low ending lag, such as {{SSBB|Meta Knight}}'s [[down smash]] and {{SSBB|Snake}}'s [[up tilt]], to remain difficult to punish out of shield if spaced properly.

The approximate formula for frames of shieldstun in ''Brawl'' is <code>d * 0.375</code> rounded down (shield damage dealt by the move is not factored into this formula).
-{{SSBB|Yoshi}}'s shield is no longer immune to shieldstun, and unlike the rest of the cast in the transition from ''Melee'', his shield still takes 15 frames to drop. In combination with him having one of the slowest shield grabs, as well as still being unable to jump out of shield, this gives him significantly worse defensive options than any other character.
 ==In ''[[Super Smash Bros. 4]]''==
-In ''Smash 4'', shieldstun was originally thought to have been reduced again from ''Brawl'', but further testing showed this to be false. The formula for shieldstun frames prior to version [[1.1.1]] was <math>(d\times1.3+2)\times0.3</math>, with rounding down performed twice; first for the portion in brackets, then the final result. This resulted in barely higher shieldstun than in ''Brawl'', being either the same or with a single extra frame for most damage values, while moves that dealt less than 1.54% damage still inflicted none at all. In combination with the cast's generally higher landing lag, ending lag, and/or lower damage values, especially for top and high tier characters, as well as shield pushback being decreased (with the effect of [[edge slipping]] on it being particularly weakened), this originally made ''Smash 4'' an even more defensive game than ''Brawl'', with heavy reliance on out of shield retaliation instead of direct pressure. {{SSB4|Yoshi}} was also given the ability to jump out of shield and the standard 7 frames of shield drop lag, no longer differentiating his shield game heavily from the rest of the cast.
+In ''Smash 4'', shieldstun was originally thought to have been reduced again from ''Brawl'', but further testing showed this to be false. The working formula for shieldstun duration in ''Smash 4'' prior to patch [[1.1.1]] was originally <code>d * 0.39</code> rounded down (bonus [[shield damage]] dealt by the move is not factored into the formula), which results in barely higher shieldstun compared to ''Brawl'' [http://smashboards.com/threads/mechanics-techniques-discussion.368206/page-40].
-However, following version [[1.1.1]], shieldstun from [[Specials: Direct|direct]] attacks was increased dramatically, to the point of being higher than in ''Melee'', and received further specialization for various cases. The new formula is <math>d\times0.58\times i\times p+2</math> rounded down, with the values corresponding to the following:
+However, following patch [[1.1.1]], shieldstun from [[Specials: Direct|direct]] attacks was increased dramatically, to the point of being higher than in ''Melee''. The new formula is <code>d * 0.58 + 2</code> rounded down, and for [[indirect]] attacks (such as [[projectile]]s), the formula is now <code>d * 0.29 + 2</code>. [[Powershield]]ing further multiplies the amount of shieldstun by 0.66, so, for versions 1.1.1 and later, the formula is <code>d * 0.3828 + 2</code> for direct attacks and <code>d * 0.1914 + 2</code> for indirect attacks when the attack is powershielded.
-*<math>d</math>, like in the previous formulas, is the damage the attack would deal if not shielded.
-*<math>i</math> is 0.5 for [[indirect]] attacks (such as [[projectile]]s), and 1 otherwise, resulting in a general multiplier of 0.29.
-*<math>p</math> is 0.66 if the attack is [[perfect shield]]ed, and 1 otherwise, resulting in general multipliers of 0.3828 and 0.1914 for direct and indirect attacks, respectively.
-As a result of this formula, all attacks once again inflict shieldstun regardless of their damage output, and direct attacks are especially safer, to the point of various landing aerial attacks only being a few frames negative on shield with proper timing. In turn, perfect shielding having an effect on shieldstun ties further into its purpose of being much more precise, yet much more rewarding than normal shielding. Compared to previous versions of ''Smash 4'', these changes allowed several characters to play more offensively, though due to out of shield options still being relatively fast and highly rewarding, as well as the aforementioned damage/lag nerfs, the game remained generally more defensive than ''Melee''. On the other hand, the specific multiplier for projectiles made them generally safer as well, but to a lesser extent and only up to high damage values, preventing powerful ones such as [[Charge Shot]] from becoming too difficult to punish.
+Version [[1.1.3]] of the game [https://twitter.com/Ruben_dal/status/990306476219666432 added] an additional wrinkle to shieldstun: if a character is trapped in shieldstun for 10 hits, they are allowed to cancel it with a [[roll]] or [[spot dodge]], and the [[intangibility]] of either option comes out immediately on frame 1, regardless of their coded startup. Practically, there are very few moves that can hit a shield enough times for this to trigger; the looping hit of a charging [[Aura Sphere]] is the most noticeable. In the case of said move, this mechanic allows shielding characters to escape it if they are trapped by it at the ledge, where they would otherwise be forced to [[shield SDI]] or have their shield broken.

 ==In ''[[Super Smash Bros. Ultimate]]''==
-Shieldstun has been adjusted further in ''Ultimate'', with more specific cases introduced than in ''Smash 4''. The new formula is <math>d\times0.8\times t\times m+2</math>, rounded down<ref>https://twitter.com/BenArthur_7/status/1073252767496617986</ref>, with the values corresponding to the following:
+Shieldstun has been adjusted further in ''Ultimate'', with the new formula being <code>d * 0.8 * m + 2</code>, rounded down<ref>https://twitter.com/BenArthur_7/status/1073252767496617986</ref>. '''d''' is the amount of damage the attack would deal if unshielded (without counting shield damage), while '''m''' is a multiplier that depends on the type of attack used:
-*<math>d</math>, like in the previous formulas, is the damage the attack would deal if not shielded.
+*[[Smash attack]]s use a multiplier of 0.725, effectively resulting in the same 0.58 multiplier from ''Smash 4''.<ref>https://twitter.com/BenArthur_7/status/1079237233192910849</ref>
-*<math>t</math> is 0.725 for [[smash attack]]s, 0.33 for [[aerial attack]]s (excluding [[grab aerial]]s and landing hitboxes), and 0.29 for indirect attacks (such as [[projectile]]s); due to this, the former results in the same general multiplier of 0.58 as in ''Smash 4''<ref>https://twitter.com/BenArthur_7/status/1079237233192910849</ref>, while the other two result in general multipliers of 0.264 and 0.232, respectively. For indirect smash or aerial attacks (such as {{SSBU|Mega Man}}'s [[forward smash]] and [[down aerial]]), only the indirect multiplier is used. In other cases, the value is 1.
+*[[Aerial attack]]s use a multiplier of 0.33, with the exception of [[grab aerial]]s and landing hitboxes, resulting in an overall multiplier of 0.264.
-*<math>m</math> is a '''shieldstun multiplier''', a move property new to ''Ultimate'' that can be specified for each hitbox. This is mostly employed by [[rapid jab]]s and [[dash attack]]s, which use a higher multiplier than usual to either prevent shielding opponents in range from escaping them or to decrease their [[punish]]ability (respectively). However, a few other moves possess them as well, such as {{SSBU|Ridley}}'s [[Skewer]], which uses a much lower multiplier than usual (0.2×) to prevent its skewering hitbox from otherwise producing ludicrously high shieldstun, as it deals 45% damage (likewise, it has a high amount of negative [[shield damage]] to prevent it from instantly breaking a shield). Shieldstun multipliers also affect the amount of pushback inflicted on the shielding fighter, further affecting how punishable attacks are out of shield.
+*Indirect attacks (such as [[projectile]]s) use a multiplier of 0.29, resulting in an overall multiplier of 0.232. For smash and aerial attacks that are also projectiles (such as {{SSBU|Mega Man}}'s [[forward smash]] and [[down aerial]]), only this multiplier applies.
-*[[Perfect shield]]ing no longer directly affects the shieldstun duration. Instead, perfect shielding characters enter a unique state that allows them to act 3 frames earlier compared to the shieldstun they would receive if used against a direct attack, and 1 frame earlier if used against an indirect attack, barring specific cases.
+*In other cases, the multiplier is 1 by default. However, specific characters' moves that are not in the above categories can also have their own '''shieldstun multiplier'''. These are mostly employed by [[rapid jab]]s and [[dash attack]]s, which use a higher multiplier than usual to either prevent shielding opponents in range from escaping them or to decrease their [[punish]]ability (respectively), but a few other moves possess them as well, such as {{SSBU|Ridley}}'s [[Skewer]], which uses a lower multiplier than usual to prevent its sweetspot from otherwise producing ludicrously high shieldstun, as its first hit deals 40% damage. Shieldstun multipliers also affect the amount of pushback inflicted on the shielding fighter, further affecting how easy or difficult it is to punish moves out of shield.
-As a result, shieldstun remains unchanged for smash attacks compared to ''Smash 4'', but is increased for direct special moves and all other ground attacks; [[tilt attack]]s in particular are noticeably safer on shield. Conversely, it is decreased for aerial attacks and projectiles, most significantly the former. Further adjustments in ''Ultimate'' include [[short hop]]ped aerial attacks having a 0.85× damage multiplier, further reducing the shieldstun of some of them (albeit slightly), and [[stale-move negation]] applying on shield, weakening repeated pressure with a particular attack. However, due to the universally lower [[landing lag]], the general safety of aerial attacks on shield remains unchanged, with some of them being slightly safer. Furthermore, shield dropping takes longer (11 frames instead of 7), while [[shield grab]]bing after shieldstun has increased startup by 4 frames. Overall, attacking shields in ''Ultimate'' is more favorable, with options to safely punish out of shield being riskier (albeit still highly rewarding), promoting more offensive play.
-The ability introduced in version 1.1.3 of ''Smash 4'' to dodge-cancel blockstrings of at least 10 hits returns as well, and is now applicable to several other moves, most remarkably every [[rapid jab]], due to their increased shieldstun and much faster hit rate. This renders it vastly more useful for punishing such moves, as in the case of rapid jabs, the shielding character can usually roll behind the attacker, who will then be forced to unleash their rapid jab's finisher and become much more vulnerable. This mechanic's larger notoriety has led to it being referred to as '''shieldstun canceling''' by the community.

Overall, attacking shields in ''Ultimate'' is more favorable, with options to safely punish out of shield being riskier (albeit still highly rewarding), encouraging players to focus more on offense.
-Version {{SSBU|9.0.0}} made other smaller adjustments to shieldstun:
+The ability to cancel shieldstun with a roll or spot dodge after being locked in it for 10 hits returns from ''Smash 4'', and is now applicable to several other moves, most remarkably every [[rapid jab]], due to their increased shieldstun and much faster hit rate. This renders it vastly more useful in punishing such moves, as in the case of rapid jabs, the shielding character can usually roll behind the attacker, who will then be forced to unleash their rapid jab's finisher and thus become much more vulnerable. This mechanic's larger notoriety has led to it being referred to as '''shieldstun canceling''' by the community.
-*If multiple attacks hit a shield on the same frame (such as {{SSBU|King Dedede}}'s Gordo and hammer swing in [[Gordo Throw]]), each attack's shieldstun is individually calculated, and only the highest result of such is taken. In previous versions, the highest damage and highest shieldstun multiplier of each move was used, resulting in higher shieldstun than if any of the attacks hit individually.
-*Shieldstun caps at 60 frames, making ''Ultimate'' the only game in the series with a shieldstun cap. However, this is only realistically possible to reach if [[spirit]]s are used to significantly boost an attack's damage output, and even then, a normal shield will usually take more than enough damage to break, so this can only be noticed with a perfect shield.
 ===List of moves with shieldstun multipliers===
-Due to a glitch, even if a move has a shieldstun multiplier only coded for specific hitboxes, the game applies the multiplier to all hitboxes of the move during frames where the specified hitbox is present. Likewise, if a move has different shieldstun multipliers for each hitbox, the multiplier for the hitbox with the highest ID number applies to all hitboxes, and other multipliers are ignored. This is noticeable for [[Areadbhar]], where the sweetspot's shieldstun multiplier applies to the entire move for all except the grounded version's first active frame (where the sweetspot isn't present), and {{SSBU|Kazuya}}'s forward smash, which has a 0.1× multiplier for the sourspot and a 1.75× multiplier for the sweetspot, but the latter applies to both.
