Dunno if this is where I should post it, my AP does 102 damage a shot to them (Used a Elite trueshot), it took 3 clips. Therefore, it had done 1836 damage. I'm going to take a wild guess they have 1800 HP, just wanted to tell everyone this for certain help.
Hope this helped!
Oh yeah, I remember doing similar tests. I think I ended up with 1800 too, as I've had damage combos that was around 1780s or so that they survived from.
Thorough testing could also incorporate how the health scales when 2, 3, and 4 people are in a party to start off with the idea of how HP truly scales. (My personal theory is a 25% increase for every additional player).
Oh yeah, I was in a party of two. Will test rest some other time.
