aura is having a MUCH greater effect than you intend. enemies with an aura of 2 take ~1/3 damage, and 3-4 aura makes them nigh invulnerable. i managed to get 3 control buffs on one run resulting in a min/max damage of around 35 million, but my attacks would regular hit for 1,000 or less damage because by that point every enemy had 3+ aura. at least i ASSUME thats whats causing the insane damage reduction, as there dosent seem to be anything else providing damage reduction.
