A tech, officially referred to as a breakfall in Super Smash Bros., absorbing damage in Super Smash Bros. Melee, and ukemi (受け身) in Super Smash Bros. Brawl, breaking your fall in Super Smash Bros. 4, and a fall break in Super Smash Bros. Ultimate, and Passive internally by the games, is an action that can be performed when the player's character hits the ground, a wall, or a ceiling while tumbling (or reeling). To tech, the user must press a shield button a certain period of time (20 frames in all games except Smash 4 and Ultimate, which provide 8 frames and 11 frames respectively) before hitting the surface. After that, a player won't be able to tech for 40 frames (30 in Smash 4), preventing them from simply mashing the button to execute it. If this is done right, the user will negate most lag and prevent themselves from being on the wrong end of potential punish opportunities. Additional button or control stick input can cause different types of techs.
The word "ukemi" refers to a rolling technique used in Japanese martial arts when taking an attack. The name has found its way into several (mostly fighting) games, such as the Soul series, to describe similar fall recovery moves. The Japanese word ukemi can also mean "passive", hence the internal name.
The word "tech" is borrowed from the competitive communities of other fighting games and traces its origin back to technical bonuses awarded in Capcom games for performing special maneuvers to escape grab attacks and get much less damage and more recovery time.
Types of techs
A standing tech, standard tech, or neutral tech is a neutral, ground-based tech performed by simply pressing a shield button before a tumbling character comes in contact with the floor. The character will experience a brief period of intangibility and quickly bounce from the ground into a standing animation. The player will also grab any items that he or she comes in contact with.
A rolling tech (or PassiveStandF and PassiveStandB, depending on the direction chosen), also called a techroll, is a ground-based tech performed by tilting the control stick left or right when teching. The character will bounce from the ground into a roll-like animation during which the character moves left or right while intangible. This can allow characters to roll away from their impact point to complicate tech-chasing, but takes longer to interrupt than a standing tech while granting the same amount of intangibility. Rolling against an edge will halt the roll's sideways movement.
An Amsah tech (named after Dutch player Amsah) is the combination of a rolling tech and directional influence in Melee that can be used to survive low knockback-angle attacks like Falco's down smash. It is performed by DIing down and either towards or away from the attacking character (away allows to survive longer), holding the C-Stick down for ASDI, and pressing shield during hitlag. It is also referred to as an Over tech, named after Spanish player Overtriforce.
A wall tech (or PassiveWall) is a tech against a wall. To wall tech, the player must press a shield button before hitting a wall while tumbling, though unlike with ground techs, the character must be in hitstun for it to work; simply moving towards the wall after it ends and pressing shield without canceling the animation does not allow a wall tech. As with ground techs, the wall teching character experiences a few intangibility frames, and the tech absorbs the player's momentum. However, wall techs are interruptible much faster, as the character gets off the wall almost immediately afterward instead of recomposing themselves into a standing animation. Wall teching is useful even on simple stages with no onstage walls, as the player can tech the side of the stage when hit offstage to avoid being stage spiked.
Wall tech jump/Wall jump tech
If a jump input is active when a wall tech is performed (such as holding up or pressing a jump button), then the teching character will wall jump. This is known as a wall tech jump (or PassiveWallJump). Every character can wall tech jump, even those who cannot wall jump normally. Wall tech jumps are especially useful offstage, as they can be used to recover more effectively from stage spikes, and since wall jumps incur no lag, allow the character to counterattack immediately if the opponent is in range; a notable example of this is getting grabbed by Captain Falcon's Falcon Dive offstage, which can be easily punished by wall tech jumping it and then hitting Falcon with an aerial attack. Combined with DI and SDI, it can even be used to survive other stronger moves if the player is close enough to the wall, such as the Ice Climbers' forward aerial that often ends their chaingrabs. Another notable use of wall tech jumping is when using a bomb recovery to get launched towards the stage, as it can further aid the character's recovery and prevent them from stage spiking themselves.
In Melee only, it is possible to perform wall techs on ledges. This is particularly useful when a recovering character is hit with an attack very near to a stage's ledge, as they can SDI towards it and wall tech to absorb all the knockback of the opponent's attack. This is usually performed by pressing the shield button to wall tech before pressing the control stick to SDI, because of the 20-frame window in which the player can input the tech before hitting the wall.
A ceiling tech (or PassiveCeil) is a tech against a ceiling. To ceiling tech, the player must press the shield button before hitting the ceiling and while in hitstun. The ceiling teching character experiences a few intangibility frames, and the tech absorbs most of the momentum, with the character falling afterwards. It is shown on the Super Smash Bros. Brawl tutorial video on the Nintendo Channel that it can even save a character at 999%. There are few situations where there is a ceiling for a player to tech off of, but it can occur if the player is hit underneath the stage, and frequently in the caves of life in some stages, most notably Temple. Strangely enough, a few characters such as Peach and Zelda in Melee do not get any intangibility from their ceiling tech, leaving them vulnerable for its entire duration.
Changes between games
In Smash 64, only ground techs are available (standing and rolling). Teching has an execution window of 20 frames after the player presses the Z button, and can be inputted even before the character is struck, as well as during hitlag. Additionally, unlike the subsequent Smash games, Smash 64 does not have a penalty period for techs after inputting one, meaning the shield button can be mashed to easily get one with no penalty. However, due to the prevalence of true combos, and the inability to tech on surfaces other than floors, alongside the lack of DI to get launched closer to them, the usefulness of teching is more limited than in later games, and combos that involve bumping characters into walls are effectively guaranteed, with Hyrule Castle being a notable example of a stage where they can be exploited.
In addition to normal techs, Melee introduced wall techs, wall jump techs, and ceiling techs. The mechanics to initiate a tech are fundamentally the same ones as the Smash 64 mechanics, being able to be performed for the first 20 frames before the character touches the ground, a wall, an edge or the ceiling, plus the character's recoil frames when they hit a surface. However, after this window, teching is disabled for 40 frames, even if the shield button was pressed during any instance other than tumbling. As a result, players not only have to time their tech properly, but may even be left unable to tech a hit at all if they are launched too quickly after executing a defensive action such as shielding or dodging. However, as teching can only be done with a digital press of the L or R buttons, analog inputs of such buttons do not incur this penalty.
While the mechanics to teching are similar to those of Melee, Brawl removed the ability to tech a hit on the edge of a stage, as well as buffering a tech before receiving a hit. Additionally, as air dodges can now be performed out of tumbling, and due to the introduction of hitstun canceling, teching even a few frames too early will result in an air dodge, unless the character hits a surface very quickly after entering tumbling so that they cannot hitstun cancel. As a result, teching requires more precision to perform in Brawl and is substantially less useful, being limited to a few notable tech-chasing moves like Mr. Game & Watch's down throw, as DI and momentum canceling are usually better techniques for survival elsewhere.
Footstool jumps on aerial opponents cannot be teched for most their duration, allowing them to set up guaranteed combos.
In Smash 4, teching has undergone several significant changes. The window to successfully tech has been reduced to 8 frames, down from 20, although with 30 penalty frames afterward rather than 40, and it can no longer be inputted during hitlag. However, recoil lag when a character bumps into a surface is generally longer, giving them more time to tech during this event. Meteor smashes that land on grounded opponents have also become techable, provided their hitlag does not exceed the length of the tech input window; the only meteor smash with enough hitlag to be untechable under normal circumstances is Ganondorf's down aerial, although Falco's down aerial also had this property prior to update 1.0.8.
Unlike in Brawl, when an air dodge is used out of tumbling, it is automatically canceled into a tech if the character makes contact with a surface within the first 7 frames. Since air dodges in Smash 4 have received much higher landing lag compared to Brawl, this prevents players intending to tech on the ground after hitstun ends from accidentally getting this landing lag instead if they press the shield button a few frames too early. This air dodge cancel additionally ignores the 30-frame tech penalty, so it works even if the character had pressed shield a short while beforehand.
Alongside the mechanical changes, several new situations have arisen where the character is unable to tech when bumping into a surface, either fully or partially:
Overall, teching in Smash 4 is harder to perform and more inconsistent than in previous games. However, with the changes to hitstun canceling, it has regained most of its utility in avoiding followups from the opponent and surviving deadly blows, making it a vital technique for success.
In Ultimate, the window to tech has been slightly increased from 8 frames to 11 frames, and the ability to buffer a tech in hitlag has been restored from previous games. It is also possible to tech while already making contact with walls and ceilings, but not the ground. To compensate, the shield button can be held for much longer than the 11 frame window and a tech can still be performed on the ground. Additionally, footstool jumps can now be teched, while grounded meteor smashes can no longer be teched, regardless of hitlag modifiers. Teching while reeling works on the ground once more, like in previous games.
While all of Smash 4's untechable situations have been removed (including hitting Cloud at the peak of his Climhazzard), there is now a knockback-based threshold; sustaining too much knockback at a certain distance from a surface will prevent players from teching, making stage spikes guaranteed at high enough percents. The visual indicator for an untechable move is the shockwave of the rebounding character turning red. This threshold is also much smaller for ground techs than walls and ceilings, making meteor smashes more effective on-stage on aerial opponents. Players can mitigate this threshold on walls by holding down while sustaining knockback, due to the unchanged directional influence and LSI mechanics from Smash 4.
Other changes to the teching mechanics are as of yet unknown.
Usefulness and application
Teching can save the player from KOs in many situations and is a exemplary technique for beginners to learn and practice. It can also help the user avoid combos that capitalize on the vulnerability frames from getting knocked down on the floor or bouncing off a wall.
Upon taking high damage, characters bouncing off walls or ceilings can often be knocked away too far and get KOed; this can be prevented by applying a wall or ceiling tech, saving the player from a deadly ricochet. This is especially useful in stages with caves of life, such as Temple: a character in the large lower section of the stage can survive even at very high percents and immediately retaliate from otherwise deadly blows. This unusual longevity is one reason Temple and similar stages are banned from tournaments.
The standing and rolling techs can be performed in more situations, such as allowing a character to avoid continued assault after being knocked back. However, an opponent can frequently predict a player's tech patterns and strike them again after knocking them down, requiring them to mix up their tech and getup options; deliberately setting up such situations is known as tech-chasing.
Ledge teching helps keep the character on the stage, or at least making it possible to recover to the stage.
