1) Voodo has an estimated chance of 30~35% to curse your opponent (25% hp decrease each turn), not sure about voice weight trap.
2) Dunno
3)If you use it wisely.
4) It does damage? I never noticed, but I think its not that great.
5)It's not always cool to have the exact same set of skills/talents as the opposite element.
