Crumble undead is a unique combat spell available at level 39 Magic. It can only be used on undead monsters, such as ghosts, skeletons, and zombies, but deals extra damage to them. Crumble undead costs 2 earth, 2 air, and 1 chaos rune to use, and yields 98 experience per successful cast.

Using it on target practice zombies underneath the Magic Guild can earn up to 110-130k experience per hour. Access to the guild requires level 66 Magic, or 63 if the player drinks a Wizard's Mind Bomb.
