great info as always, is there a way of seeing the exact HP numbers you're quoting on bound demons or is it just based on out of game math?
pure math and making assumptions about some untested mechanics
big question is whether normal monster upgraded to unique by bind demon gets the 2x life of a unique or not.
anyway imo its too easy to get a mob that will be virtually invulnerable in pvm, 4 million hp 91% dr regen 100k+ per second is a joke, I don't think any contrived in-game pvm setup could possibly kill it
its why its better to get the mobs with the best AI and abilities. And urdars happen to be one of the best anyway with crushing blow, smite, large collision size to eat projectiles while you teleport, and AI that does nothing but attack
venom lords as an example from TZ can be hilariously tanky with astronomical HP and immune to everything but phys but then it has AI that zigzags around and sits afk channeling a 0 damage inferno
