Pros:
-Able to fight at melee range and even stagger opponents with MLGS.
-Able to fight at long range with spells and using the element of surprise with chameleon.
-Chameleon disables the opponents ability to lock-on.
-MLGS two handed heavy attack unleashes a strong range attack. (use Repair Powder so you can spam it)
Cons
-Lowered magic defense because we have to equip Crown of Dusk and have to use crest shield because of that.
-Low physical defenses to be able to fast roll.
-Longer battles will take away your advantages since you won't have any more casts for chameleon.
Tactics are as follow.
Cast chameleon and approach opponent until you can lock on and use your spells,
You WotG if he approaches then you can either cast homing crystal soul mass or crystal soul spear and follow up with a heavy two handed MLGS attack.
