defiler 'arcane defiling'
Defilers draw energy from living things around them to fuel their arcane powers, slowly destroying their environment in the process. The arrival of a defiler in woodland areas often triggers elven warparties in a bid to preserve the land, though most such efforts result in a necklace of pointy ears for the defiler. The arcane defiling skill increases the caster level of all maledictions cast by the defiler by (20+level)/5. This includes all hostile spells with a duration, as well as energy drain.
