Next we shall need to find a stable and portable source of energy to keep the ectoplasm active. I've heard rumors of a mighty elemental called Magma Lord Bokk, whose heart is a powerful magma core - an endless supply of heat! It's said he can be found in the Burning Steppes, south of Blackrock Mountain. Bring the magma core to me and we shall have enough juice to power the extra-dimensional ghost revealer!
