Note: "All Remaining Points Or None" Means its your Choice Max Chance% to Hit %Target% or Max Life (No Risk Of Dying To Extra Strong Lorde De Seis)

Tip: Do Not Teleport With Axes In Hand (With High Ping), Use Howl and Leap to Kill Lorde De Seis and if the Boss is crowded use it for that too, If amplify proc's from your mercenaries Atma's Scarab take Full Advantage and use Whirlwind (they die extremely quickly while amplified).
