[Chaos]

The following Youkai skills have been changed into Spells. Note that Evoke skills do not receive damage bonuses from items that would boost Spells, nor do they receieve Power bonuses from Tome weapons. This change simply makes Silence a more dangerous status for Summoner classes and may force them to summon the Youkai in question if they want the skill to be used.

Yeah, this isn't a bug.
