Glitch Mode is a powerful form of executing the enemies, better reserved for threats that your type has a disadvantage for or against bosses. You will actually acquire your first run in Glitch Mode by running through the main story/prologue, against the dummy boss there. When your character reaches 80% or higher, they will fuse with their Buggy and break into a psychotic state. This increases the damage dealt to the enemies as well as unlocking a powerful Glitch finishing move. These moves also come with a refreshing buff, such as recovering health, SP, or applying a buff/debuff (according to the one who executed it). Just be aware of one thing: do not let your Glitch state reach 100%; full corruption will end with your character being knocked out. Furthermore, if you fail to use the Glitch supermove in the third position of your attack, you will stabilize and your corruption will reset to 0%.
