Brace

Brace, also known as Grid, Endure/Endur, or Bear, is a recurring ability in the series. It is generally a defensive ability meant to reduce damage or prevent death.

Final Fantasy IV
Brace is the ability of Yang, and can be learned by any character in the 3D versions by using the Brace augment, obtained from Yang after hitting him with the Frying Pan, if he was given two Augments before leaving the party. When used, it will reduce all damage the user takes by 75% in the 3D versions while in the non-3D versions, it acts as a Protect spell with a casting time of 1. When equipped on a character that levels up after reaching level 71, it provides +10 HP and +1 Stamina.
