Wall tech
A wall tech is a tech against a wall. To wall tech, the player must press L or R 20 frames or fewer before hitting the wall, while tumbling or in hitstun. 20 frames after each press is a 40 frame downtime window where a wall tech cannot be done, so mashing buttons reduces the player's likelihood of teching. As with normal techs, the wall teching character experiences a few frames of invincibility, and the tech absorbs most of the his or her momentum.
Ledge tech
A recovering character can use a form of wall tech to survive an edge-guarder. If the recovering character is hit with an attack very near to the ledge, he or she can DI towards the ledge and wall tech to absorb all the knockback of the enemy's attack. This is usually performed by pressing L or R to wall tech before pressing the control stick to DI, because of the 20 frame window in which the player can input the tech before hitting the wall.
Wall tech jump
The player may press X, Y or up to wall jump when wall teching. This is known as a wall tech jump. Though only eight characters can wall jump normally, every character can wall tech jump.
