What kind of damage do the brainstormer beams do?

Wondering if the Brainstormer beams count as splash/grenade/AOE/something else?

no one’s gotten back to you in 3 days, so i’m gonna guess something else? idk, it seem like it does the most damage from those beams themselves rather than the bullets. really doubt it’s grenade damage if that helps with the order of elimination.

It doesn’t seem be splash/aoe/grenade. The beams must be their own damage type now or just regular bullet damage
