Unstoppable Incendior
From Destinypedia, the Destiny wiki
Unstoppable Incendiors are advanced pyrotechnical Champions employed by the Cabal, armed with abilities that negate staggering and bear better stamina than their peers.
Gameplay
This Incendior will always press their opponents, raining down their flaming bolts of magma at their targets, but prefer to get close as fast as possible for a Compression Blast, burning and knocking their opponents back. They will not stop or stagger unless a Guardian uses Anti-Unstoppable abilities, which will temporarily stagger the Incendior and provide some time so sink some damage into the elite trooper.
