For all you Dark Knights out there

Achilles. Beholder's heal does not reduce the amount of hits that skelegons can kill you in while in bezerk, but achilles does.

Well that makes sense, Achilles is a permanent defense, therefore it would decrease the number of hits needed overall. Aura wouldn't do that because it heals you over time, so if skelegons did enough damage to kill you in one hit Achilles would reduce that damage before it hit you. Aura would heal you AFTER taking the hit, so you'd already be dead by then.
