Edit: Figured I would update for anyone curious. Solved this thanks to apewiththumbs mentioning Storm. When my action skill element is electric the ricochets are treated as Storm instead of Firestorm, but when the element is fire it produces the Firestorm effect.
I don’t know if this is a legendary effect, an Amara effect I hadn’t seen before, or what. Not even positive it isn’t some kind of bug. I can’t even think of a way to search properly to make sure it hasn’t been brought up by others. I’m at a loss trying to figure out where these are coming from. About every ten enemies or something 5 blue orbs appear above an enemy (sometimes the one I shoot, sometimes one near them) and a red beam from each damages them. Playing as Amara Mayhem Mode level 1 TVHM, lvl 50. Do any of her skills cause this that anyone knows of? I have points in Fist of the Elements and Brawl trees, can post a build if I need to.
Legendaries I have currently are Dangerous Kill-o’-the-Wisp, Expert Firestorm, Firestorm (Tediore grenade), Electric Slide Cosmic Crater, Burning Gratifying Laser-Sploder, and Unending Magnificent. Then a Storm Front unequiped. Shield and class mod are normal purples. I’ve looked up each of these and nothing is describing them as having this effect.
The only thing I can think of at this point is some sort of weird interaction between the Firestorm sniper and the Indiscriminate skill’s ricochet. I want to figure this out because it seems to do decent damage so I want to make it happen more if I can. Will post a screenshot if need be and I can get one when it happens.
Edit: Was able to get this to happen again.
