I decided to create a tome wielding unarmed hero. It was working really well until I got the Malleus Maleficarium which does 2+(.55*magic power) damage in an 2 square wide AOE on melee. I thought this was supposed to casted around me, but it cast the spell around my opponent! This leaves my opponent completely unharmed and me 10+ damage each time I do a melee hit. I then found the King in Yellow tome which does the same effect.
