Blue Mage.
I envision it being a gauntlet(s) user that absorbs aether from its enemies and uses their skills against them. It's a tank that focuses in on debuffing enemies with all the various skills you learn in battle.
Obviously there are only so many skill it could learn so each species would be broken down into simpler catagories. For example humanoid, serpent, voidsent, beast tribe..etc as well as magic.
