Please state how long the buffs/debuffs last for, Also give the first power some cast time or cool down, otherwise I can see it spammed to create immortal creatures. 
Also your last spell CANNOT be a instakill. Maybe it deals a immense amount of DMG (see necromancers Death Touch, Or Unholy word). And you may want to split the T3, T4, and T5 skills in to two 'branches' where you can only access one branch. otherwise it will seem a little OP, maybe one is about DOT and one is about Healing?
