Heretic runes no longer have every single transparent pixel set to 1 alpha, to make it easier to click on objects. Clearing heretic runes with mansus grasp takes 0.4 seconds of standing still, to prevent you from accidentally clearing it in combat. Added code for effect remover element to use a windup if set.
