@degenerator Alright I'll give, but you've gotta say please next time! The correct answer was aspect of the mountains
Reference to the need to wait until 6 mana cores to cast. The fate part is the idea that you change something into an elemental, therefore altering the life (fate) that it had, for better or for worse is up to how you use it.
When you cast the Spell the minion that transforms deals 5 damage to any nearby enemy minions (in most cases, killing them outwright). If you notice after the transformation, the elemental is made of ice and rock thereby ridding them of their fleshy parts (the asunder part came from the damage it deals to surrounding enemy minions and the fact that I imagine it to explode when turned) Notice that spells are cast, minions are summoned, and artifacts are equipped
Aspect of the mountains can be cast from any position of the board on any minion(I neglected minions that cannot be targeted by spells, but it's a haiku cut me some slack will ya?). The you is a minion.
