unfortunately in the current state, adding more spells could cause more issues. I think they have to give us more control over spells first.

example, other day fighting bakka, bst had him down to 20%, puppet went over nuked him with blizzard 5, cured him for 3600 hp. I didnt know ice healed him, but my mage puppet was useless on that nm, had to switch to another puppet. Just stupid I had to do that.
