The biggest tip I can give you is to have as much gold as possible before the final boss fight and roll weapon passive abilities to match your current skills, such as +40% when the opponent is burned/poisoned. Which help me to me kill hotk under 4sec before it goes to 2nd phase with only 27 scrolls.
