When this move is used, Rosalina's Luma will quickly fire out three Star Bits, which serves as a mid-range attack. Despite their appearance, the Star Bits are not projectiles, but rather disjointed hitboxes; this makes the attack immune to reflection, absorption, and Villager's Pocket (this is no longer true in SSBU). This move only makes use of Luma, as Rosalina simply waves her wand when performing it. As a result, this move will not work if Luma has been KOed. This move is a very useful spacing tool in competitive play, thanks to the aforementioned disjointed hitboxes and high range of the move, and can be also used when Rosalina is far away. This means that Luma can fend off opponents trying to send it off the space using the move without putting Rosalina, who may be offstage, at notable risk from the lag generated by other moves.
Special Move customization was added in Super Smash Bros. 4. These are the variations:
Unlike the default version, both variations are proper projectiles that can be reflected and absorbed.
Star Bits are a common collectible item that appear in Super Mario Galaxy and its sequel, Super Mario Galaxy 2. They can appear when Mario defeats an enemy with his Star Spin or hits a ? Block, and are also found in various places in the galaxies themselves. They can even, though rarely, fall from the sky. Star Bits can be fired at enemies using the B button to temporarily stun them. Doing this to Lumas, however, will feed the Star Bits to them, as they consider them a delicacy.
This is especially true for Hungry Lumas, a unique type of Lumas who demand to eat substantial amounts of Star Bits, upon which they transform into a new planet or galaxy for Mario to traverse, or give him a 1-Up or Life Mushroom.
