Sheik performing a ceiling tech.
A
ceiling tech is a
tech against a ceiling. To ceiling tech, the player must press L or R 20
frames or fewer before hitting the ceiling, while in hitstun. 20 frames after each press is a 40 frame downtime window where a ceiling tech cannot be done, so
mashing buttons reduces the player's likelihood of teching. As with normal techs, the ceiling teching
character experiences a few
invincibility frames, and the tech absorbs most of his or her momentum. There are few situations where there is a ceiling for a player to tech off of, but it can happen quite frequently in the fight club of
Hyrule Temple.
