I used the pause button for my tough fights so far. I just keep my eye on my adn DK health meter and when it gets down too low, hit the pause button, drink up on potion and when you unpause, you have full health again. thats the beauty of the game is being able to still complete certain tasks or move inventory around, use potions while in pause mode, so when you return to the game you are all healthy again.
