Kiss of Blessing bug

The Kiss of Blessing bug is a bug from the game Final Fantasy V

Using the Chemist's Mix command, the Kiss of Blessing can be made by mixing a Maiden's Kiss with a Holy Water. Doing so gives the Haste, Image, and Berserk status to the target. However, due to the coding, the Berserk effect overrides everything, even boss immunity.

Using this on a boss can cause them to not perform any script used in the battle. Two particularly notable effects are during battles against Exdeath; in the 1 on 1 battle versus Galuf, using it will make the battle unable to end, as Exdeath is actually defeated by a script prompt. Using it it on the Exdeath battle in the Dimensional Rift makes him unable to transform into NeoExdeath, allowing you to complete the game without defeating the final boss!

This bug was fixed for the GBA version.
