Destiny 2 Lightfall - Season of the Witch
Foetracer seems to be doing a little bit of trolling right now, alongside its normal use of providing weapon surge x4 (25% bonus damage) to weapons of a matching type when landing an ability on a powerful target & spawning a subclass pickup if that target is defeated by empowered weapons. It also activates from a whole host of non-ability interactions.
From a base of glaive projectiles & powered sword hits instantly proccing this exotics weapon damage boost theres something for pretty much every subclass which will also activate Foetracer.
To give examples of some of the completely wild interactions here is a few of them:
Tangles will activate foetracer (but only if you are holding a sword)
Unravelling enemies will activate foetracer if they are punched with an uncharged melee
When Gunpowder gamble is ready all elemental weapon hits will activate foetracer
jolt from a weapon source wont activate foetracer, but chain lightning from another jolted enemy will do
if an enemy is frozen from chill clip and shattered with an uncharged melee it will activate foetracer
