What if it was given a SWA + Dark Elemental ATK scaling up front, and did %extra damage based on missing health? That would keep bosses from outright dying, and since lowering 1,000 hp people is harder than 500, it wouldn't have sweeping differences in efficiency.

In this case, the health threshold requirement would be removed.

(To note, I don't mean dealing a portion of the target's missing health like the Soldier skill Execute, but rather the damage of the spell itself is multiplied based on missing HP)
