Okay, I finally found a use for Call of Fire. Converting your melee attack to ESP. You run a full CMP board. Now that you have an ESP attack for Forestallment or Counterattack, you get to trigger Magic Relief's healing off of those, and you also get to use CMP on it to begin with so you get 100% damage on them with Magic Explosion. If you're at full stacks you have 100% chance to proc Magic Explosion, which refunds you 25 AT. Combine with Lunatic Beast or Distorted Heart.
