Before entering the rift for the final battle, check your inventories. You will be in trouble if your DK has all your potions, weapons, charms and rings etc. His inventory will no be available to you once you enter the rift. It is best to take everything you need or want to keep. If you plan to use summoning dolls in the battle, take away all the dk's skill points and apply them to your summoning dolls. If the DK has sharpen weapon, choose your final weapon and let him max it for you before taking the skill points away. Disarming or weakening him before entering the rift will not work, since he will always have fixed stats and a 2 handed hammer.
If you have enough money you should unlearn any skills that your Hero will not need in the final battle and redistribute them in more useful skills. Damian is the toughest enemy in the game and he will regenerate quickly so plan your battle strategy before entering the rift. </span>
