Umbral Blast

The Umbral Blast is the charged attack of the Orphic Flame Tank, the Taken version of the Cabal Magma Launcher. The Cabal Magma Launcher fires puffs of Solar flame that can leave lingering fire, and its charged attack is a short-ranged Compression Blast that knocks the target back far.

The rare Taken Incendior units carry an Orphic Flame Tank. It still fires Solar flame, though tinged black, but its charge launches a long-ranged explosion that deals Solar damage and leaves a pool of burning Void flames behind.

Do not confuse it with Umbral Flames, a separate Vanguard fragment quest that has no link to this attack.
