Some descriptions of skills also say that the skill is ALWAYS neutral property (AD, SC, MR, occult...). Though you still can't reduce it's damage with Deviling but rather increase it if the opponent uses an elemental weapon.
It's not always entirely as the description says.
Hmm, what does the drac do for the leecher/leechee? u__u
The one who has it equipped gets more EXP. In case of a quad dracula you get 60% more exp. Doesn't work for angels and demons or dragons (don't remember which one)
