i think they need some rebalance, wiz d1 and d2 are quite crappy while d3 is just crazy.
priest dual spells olso need some rebalance,d3 spell does decent damage around 10-12k to db with 130 tactics but is way to random,hits can go from 0 to 4 and that in case the oponent decide to stay close.
as for d1 i think this skill need to be replaced, an area heal to hp/food and state, considering that restoring food and normal state in area is not something that one will do very often this spells only worth is for area heal but for doing that priest already have 1 skill.
