Syntax: cast 'energy drain' <victim> This spell forms a small conduit from the Negative Material Plane to sap the mana and movement points from its target, causing a small amount of damage as well. As such, undead and other creatures that thrive on negative energy are immune to this spell. If a target fails his saving throw vs. magic, his current mana and movement are reduced by half; a successful saving throw lessens that amount.
