The Koleda, S11, and Grace team is working out surprisingly well.

Koleda and S11 swap around to build stun and fire damage, and then when the enemy gets stunned, S11 wails on it while it burns, then near the end, I swap in Grace who at this point has full charges and dump them all for Disorder burst damage. That's basically the cycle. Grace barely gets any up time and is basically a mechanism to trigger Disorder.
