I've just deleted the concept of stamina from Minermancers. We originally had stamina so that the player could have a sprinting speed faster than enemies, but you couldn't just run away forever. However in practice, sprinting is self-limiting because of cave geometry and obstacles, and the fact you can't do anything useful while sprinting (mining, casting spells). It's less annoying and cheaper on the attribute system just to remove it, and I know some people hate stamina mechanics
