From Destinypedia, the Destiny wiki
The Combustor Valus is a Cabal Blood Guard Incendior encountered on Mercury where they lurk in the Pariah's Refuge. Their Bounty can be picked up from The Spider as a part of a weekly interval. Unlike a lot of his Red legion brethren, The Combustor Valus would be successful in securing a Lost Sector for himself and his forces yet fall to the Guardian regardless. The only other known Cabal to do this is the Blood Cleaver.
The Combustor Valus and some of their allies, more likely two Slug Rifle wielding Phalanxes, will be in the middle of the arena lurking within a Cabal Dome Shield. Within the Dome Shield is a burning area-of-denial which can quickly sunder health. A way to alleviate this is to kill Honored Incendiors which roam the arena and Dome Shield. Once killed, the Honored Incendior will drop a Shield buff which provides an extremely resilient overshield. The encounter will end with the Valus's demise.
