Haku no Shukufuku doesn't actually appear in the skill book, but they were nice enough to add the description in the data anyways. I interpreted their use of 攻撃力 as referring to WATK, since they bother to explicitly use 魔法攻撃力 to refer to MATK, but I could be wrong.

I'm actually not sure if this changes when you're 4th job, because the description for Haku no Shukufuku changes there to not mention anything about his equipped fan though.

This is why I'm a tad confused. It mentions both WATK and MATK in the Gensei Haku skill description (The bottom is Haku no Shukufuku), but in the regular Haku skill it mentions just "Attack".

Ignore the actual numbers though, I think the Haku buff itself's stats were modified when I leveled Gensei Haku, which is why all the numbers are the same.
