The Priest base class deal in both healing and curses. At level one, a priest receives the ability to cast 10 first level spells per day and automatically learn two spells. Each level they are given the same structure in each level of magic (ability to cast 10 spells of that level, and two spells for that level). At level 5 priests will have the ability to cast 50 spells (10 in each level). After level 5 the priest receive a talent point to invest in specialized ability trees (Shadow Priest and Divine Priest). How you invest your talent points is up to you. Solely divine? Solely Shadow? Maybe create a hybrid?
