Larian Studios Forums Divinity: Original Sin 2 Divinity - Original Sin 2 - General Is there any reason to level up pyro?

I think the biggest thing skills need is a higher level cost for higher level spells. So fireball would take 2 or 3 pyro or else it would cost more ap to use. This would be an easy way to give more meaningful decision to your choices without as much need for it to be as balanced, unlike now where they all give only stats for leveling them up.
