On AST I got AS4 dummy to 1% many times with 210 armor and weapon, 200 belt and 190 accessories (one 185 ring). 201 average. Finally beat it with a second to spare. No food or potions. Your weapon makes a big difference I think. Also if you have higher left side gear than right side like me, your dps will be bigger for that average item level because armor has more stats. I probably wouldn't have made it if I had 210 accessories and 190 armor for example. I haven't unlocked midas savage yet but it's gonna be fun to test it.
