Damage bug related to the corpus railjack enemies called vambacs

[CrusaderTheFirst]

It's really weird but can be very annoying. Vambacs damage is very inconsistent. It ranges from a reasonable 800 damage at level 60 to 2800 or more damage at the same level.

I've been experimenting in the simulacrum and I've been testing things quite a bit. I don't think it has something to do with how close you are to the explosion or direct hits because even direct hits do inconsistent damage.

I even tested this with multiple types of vambac enemies. It seems all the vambac types have this bug.

It might  be an intended feature but I think it's a bug because things don't seem right to have something this inconsistant. Especially dealing reasonable damage to being able to one shot or two shot most warframes.
