I thought of this a little while ago and was wondering if you guys could confirm it.
I read somewhere that Earth Elementals can tank a mob in black temple called Aqueous Spawns because their melee attack was nature based and the earth elemental is immune to nature damage
So I was wondering: Couldn't you theoretically turn Hydross into poison form and use an earth elemental to tank him the entire fight(with shamans alternating them because of the 2 minute duration)? Since they're immune to nature, no matter how many debuffs Hydross puts on them, they'd still take no damage. Would this work? Or is there some way this is impossible.
