Yes. It gives it cornered( faster charge time when surrounded) and incandescent( applies Scorch and spreads on kill)
I got it in Momentum, at 40% so far just casually using it
Found it in a strike! Just a playlist one, happy hunting
Didnt realise there was one
API says it gives cornered and the new scorch perk. So faster charge time while surrounded (near 3 enemies) and when you get a kill it spread scorched on nearby opponents.
