Great Geas (VH)

Regular; Resisted by Will 
Give a subject one continuing command, such as “Never touch weapons” or “Slay all orcs.” A Great Geas does not have to be reasonably possible; it can occupy the subject for the rest of his life unless removed. Only Remove Curse will negate a geas. A critical failure on a Great Geas costs the caster an IQ point.

Duration: Permanent. 
Cost: 30. 
Time to cast: 1 minute. 
Prerequisites: Magery 3 and at least 15 Mind Control spells, including Lesser Geas (VH).

Item

Energy cost to create: 4,000.
