This spell functions similarly to lesser geas, except that it affects a creature of any HD and allows no saving throw.
If the subject is prevented from obeying the geas/quest for 24 hours, it takes a --3 penalty to each of its ability scores. Each day, another --3 penalty accumulates, up to a total of --12. No ability score can be reduced to less than 1 by this effect. The ability score penalties are removed 24 hours after the subject resumes obeying the geas/quest.
A remove curse spell ends a geas/quest spell only if its caster level is at least two higher than your caster level. break enchantment does not end a geas/quest, but limited [wish](/spells/wish/), miracle, and wish do.
Bards, sorcerers, and wizards usually refer to this spell as geas, while clerics call the same spell quest.
