Powershield canceling
Power shield canceling (PSC) is an advanced technique in Super Smash Bros. Melee, Super Smash Bros. Brawl and Super Smash Bros. 4, which refers to the fact that a player can cancel their dropping shield animation with an attack after performing a power shield. This gives the player the ability to use any attack right after they power shield an attack, as opposed to having to wait for the drop shield animation to end (which is what the player has to do if they do not power shield an attack).
How to perform[edit]
In order to power shield cancel, the player first has to power shield an attack (in Melee's case, the player specifically has to shield an attack which is not a projectile). Once they have power shielded an attack, they then need to let go of the shield button and wait for their character to drop their shield. The player does not need to let go of shield before shieldstun ends but if they hold shield for too long, it will take away the opportunity to powershield cancel. The player can then perform any ground move. In Melee, the player can input an attack on frame 2 of a shield drop while in Brawl and Smash 4, they can input an attack on frame 1 of the shield drop. In Brawl however, a forward smash and down smash can still only be performed from frame 2 without buffering and they are more difficult to perform compared to other powershield options, as mistiming them will result in a roll or spot dodge.
Powershield cancel options can be buffered in Brawl if the player lets go of shield while in shieldstun. The player can input their desired option at any point during the 10 frame buffer window, as long as the player continues to hold shield until they are no longer in shield hitlag. If the player lets go of shield too early, they will not buffer their desired option and simply drop their shield. If the player holds shield for too long, they will buffer a grab if they perform a normal attack or stay in shield if they perform a special attack. Because of this, the leniency to perform a buffered powershield canceled option depends on the amount of shieldstun a move has, with more shieldstun giving the player more leniency to let go of shield in order to buffer their desired option. For moves with no shieldstun, a buffered powershield cancel is essentially frame perfect as while the player can buffer their desired powershield cancel option, they have to let go of shield the exact frame shield hitlag ends in order to get the buffer. Altogether, the way buffered powershield canceling works in Brawl makes getting a buffered powershield cancel punish quite strict, especially for moves with lower shieldstun.
In Smash 4, the player can let go of shield at any point during shield hitlag/shieldstun and they can buffer a powershield cancel option, making buffered powershield cancel punishes easier and more lenient to perform than in Brawl.
Applications[edit]
While difficult to perform (due to the tight timing on the power shield and the varied amount of time a player can drop shield depending on the amount of shieldstun they suffer from), power shield canceling is a very useful technique as it can allow for:
- A move to be punished where it would otherwise be safe without a power shield cancel.
- A move which can be punished with a stronger punish than what would otherwise normally be possible.
As an example of this, if Zelda is hit by a move which is -5 on shield (meaning that she can act five frames before her opponent can) and she shields it normally, she has no way to punish the move, as all of her OoS options are too slow, so her opponent can avoid any punish she attempts. If she power shields the move however, she can perform a power shield cancelled down smash, which will come out quickly enough to punish the move before her opponent can act.
As a result, this is one of the main reasons why power shielding is so effective (along with it negating shield damage and having reduced shield pushback (as of Brawl)), as it allows for moves to be punished in situations where they would otherwise be safe.
Notably, Yoshi is incapable of power shield canceling in Melee and Brawl, which particularly crippled him in Brawl as even when he powershielded an attack, his fastest punish was still his frame 17 grab (due to his long shield drop animation and his inability to jump OoS) and unlike in Melee, he does not have reduced shieldstun or the ability to parry in order to compensate. This was fixed in Smash 4, as Yoshi gained the ability to power shield cancel much like any other character.
Differences between games[edit]
In Super Smash Bros. Melee, powershield canceling was easier to perform, as the game has a four frame power shield cancel window (against non-projectile attacks) and shield drop animations were 15 frames long across the board. This made powershield canceling highly effective in Melee as it meant that shield dropping after a powershield was a viable and effective option to punish attacks, which is not the case with regular shielding. A downside with power shielding however is that it has increased shield pushback, which means that power shield canceling may not always be useful, particularly against spaced moves. It could also only be performed against physical attacks, not being possible against projectiles.
In Super Smash Bros. Brawl, the technique became harder and less vital, as the power shield window was reduced to three frames (although the window against projectiles was increased from two frames to three) and shield drop animations were reduced to seven frames. The player also only has two frames of leniency to drop shield after shieldstun ends in order to powershield as opposed to three frames of leniency. Despite this, powershield canceling is still a very useful technique and power shielding received a significant addition benefit, as it now removes almost all shield pushback. In conjunction with Brawl's reduced shieldstun, powershield canceling can be used to punish more attacks and it is now a much more effective way to to punish multi-hit attacks. It is also now possible to powershield cancel against projectiles, improving the player's defensive punishment options against projectiles.
In Super Smash Bros. 4, the technique was initially extremely similar to Brawl, with the exception that the power shield window was increased from three frames to four. As of update 1.1.1 however, its window was reverted from four frames to three, making it more difficult to perform. In return, power shielding decreases shieldstun by 0.66×, compensating for the increased shieldstun in said update. This also means that power shielding now had lower shieldstun than regular shielding, giving power shielding opponents a greater frame advantage when shielding attacks, further increasing the reward of power shield canceling relative to shielding a move regularly. Another difference with Powershield canceling in Smash 4 is that it the player no longer has to hold shield until shieldstun starts in order to buffer powershield canceled options. The player can now let go of shield at any point when powershielding an attack and they can buffer their desired punish during the 10 frame buffer window. This overall makes it easier and more lenient to get optimal powershield punishes compared to Brawl.
With the lack of power shielding in Smash 64, power shield canceling was naturally not possible at all and it is no longer present in Super Smash Bros. Ultimate, due to the drastic change in how perfect shields function (although perfect shielding in Ultimate still allows the player to instantly use any of their attacks without going through the shield drop animation).
