If you encounter the enemy Adamantaimai and manage to cast Barrier, MBarrier or Big Guard (which includes both statuses) before its first turn, the Adamantaimai will attempt to use Cure. However, it does not have Cure in its attack list, which will most commonly result in a debug error message appearing advising players to hold L1, R1 and Select to return to the overworld. The reason Adamantaimai tries to use Cure is because Cure has the ability ID of 0. Adamantaimai selects an ability to use if it lacks Barrier status, and it can select another ability if it has Barrier but not MBarrier (at no other time does this enemy store an ability in memory). However, no value was ever set for the possibility of it already having both statuses on its first turn, so it never sets an ability and instead tries to use the ability set at 0. While Adamantaimai using Cure is not unusual on paper, it has no animation for it unlike its other attacks, resulting in the error message. Attempting this glitch in modern releases of the game will cause it to freeze.
