In the vanilla game, there is a set of special Guardians that can be obtained if a character dies during a full moon... 1/256 of the time. This hack removes the RNG check so that characters will always receive a special Guardian if they die during the full moon.
This hack works with both the original Japanese version and the English fan translation.
