Promethean weapons do extra damage to prometheans?

I’ve heard that splinter grenades do extra damage to Prometheans and have noticed it a few times when rushing to kill captain whatever his name is at the beginning of Stormbreak. My question is do splinter grenades do more than average damage to Prometheans and if so how much is the damage increase? Is it only splinter nades or is it all Promethean weapons? Is it only against Prometheans or all Warzone bosses?

No, splinter grenades just do massive damage to fat targets that stand in them.

Splinter nades ads OP on anything

Promethean weapons tend to work best against knights and soldiers because they don’t have a clear weak point until the armor is destroyed
