List of Contents
Fusion accidents occur during Demon fusion.
Though every merge shows you the expected resulting demon, sometimes a Fusion accident will occur, resulting in a completely different demon than what was expected.
This demon may have completely different skills and traits from its parents and will at most times a disadvantage to your party.
However, there are times that a Fusion accident will result in a demon of a higher level than you, so it could sometimes turn out for the better.
Fusion accidents can happen during any of the moon phases but it happens more frequently during a Full Moon. Be sure to always check the current moon phase on the upper left corner of your screen before fusing demons to avoid unplanned results!
