Death end re;Quest glitch mode is a status boost for your party member that can change the fate of battle. When a party member touches a “Field Bug” (or attacked), the “Corruption Level” will increase. Once the level surpasses a certain point, your character will transform into the “Glitch Mode.” This temporarily mode will increase in stats and unique abilities, God-Level abilities.
However, taking advantage of this mode can be harmful to your party. At a certain limit, your character will be unable to move and react in battle. If they happen to fall and are revived during battle, they can come back with status ailments. An interesting tactic that shows you can’t rely on abilities alone, similar to a double-edged sword.
