Rippler bug

The Rippler Bug is a bug in the game Final Fantasy VI. The Lore Rippler has the effect of exchanging statuses between the caster and the target. It was only supposed to exchange Blind, Zombie, Poison, Clear, Imp, Doom, Blink, Silence, Berserk, Confusion, Seizure, Sleep, Regen, Slow, Haste, Stop, Shell, Protect, Reflect, Reraise, and Float. However, it also exchanges Trance, Dance, Rage, Near Fatal, Interceptor, and Magitek. This means that Shadow can lose Interceptor permanently, and anyone can use a Desperation Attack even if they are not at low HP.

A second bug is that Rippler would always hit, even when it claimed to miss. This secondary bug was fixed in Final Fantasy VI Advance. However, a new second Rippler bug was created; if a character or enemy has immunity to the Imp Status, it also causes immunity to being affected by Rippler.
