Well if your looking for easy mages. Voker is pretty easy to survive with, killing takes a bit more knowledge of spells, and when to use them, when to spam them, and when to recall. Parry being the only thing you would need to actually train, I found at pinn I rarely used dispel magic, If their saves are decent hit and run with hellstream, once I have crushed some saves roll with your choice of finisher, ice storms or fireballs. Be careful with overly lagging spells early though, Hellstream is NOT a good spell to spam at all. An unseen
weapon cleave, disarm, ironarm can singlehandedly ruin your pk.
As far as RP. You could rp someone who was once a wizarding apprentice, had a master and all. Then you felt as if you needed more power, more knowledge, so you tried to read your masters tome, while you did gain the arcane power in the tomes, your mind was not trained enough to handle the immense arcana described in it, crumbling your sanity, but your magic persevered.
