I can only give you a brief explanation to my idea. Basically , he is just like a wizard but holds a wand to get his power . The spell used wherever last( not necessarily on him) will alter his attack type. His Housing space will be 10 and is barrack troop and slightly costly 10000 elixir. Normally he uses his wisp attack.
Lightning spell : point damage type green bolts of zappiness ( Land and air targets )
Heal spell : Does not do healing , but adapts valkyrie style of attack. He spreads a ring of fire which does damage to all ground structures in 4 tile radius.
Rage spell : Launches red lava bombs at slow rate that blast a bit far like a mortar shell.
Jump Spell : He attacks like a grenadier , launching exploding seeds at a long range ( 8 tiles ) but they miss sometimes with minor splash damage.
Freeze spell : Uses ice beams that freeze the opponent for 3 seconds.
Once he adapts , he will re adapt once a different spell is used.It will give more importance to spells.
