It's a remix of Cabal Breach, and to me it sounds like it could be the Cabal Emperor's theme.

Yeah is pretty cool, though the first half needs to be a bit heavier and the transition needs to either be pretty abrupt for a time when it moves to the second half of the boss battle or something or it needs a slower transition cuz right now it sounds a little messy. Other than that it's pretty good.
