Apocatastasis?

[Nutz]

As a BLM, I've found that it feels very helpful to toss on the tank (or should the tank be full health, maybe on a healer) in Titan hard. I try to time it so that it'll be up during a mountain buster, right before tumults.

Remember, the more damage that's mitigated, the less work the healers have to do to keep everybody alive, and that's a good thing.

The problem is that Apocatastasis reduces damage from fire, ice, and lightning (the elements a BLM deals with) and not water, wind, or earth so it would have no effect at all during any Titan encounter (or Garuda or the upcoming Leviathan).
