A lesser geas places a magical command on a creature to carry
out some service or to refrain from some action or course of
activity, as desired by the character. The creature must have 7
or fewer HD and be able to understand the character. While a geas
cannot compel a creature to kill itself or perform acts that
would result in certain death, it can cause almost any other
course of activity. The geased creature must follow the given
instructions until the geas is completed, no matter how long it
takes. If the instructions involve some open-ended task that the
recipient cannot complete through his own actions (such as
"Wait here" or "Defend this area against
attack"), the spell remains in effect for a maximum of 1 day
per caster level. Note that a clever recipient can subvert some
instructions. For example, if the character orders the recipient
to protect the character from all harm, it might place the
character in a nice, safe dungeon for the duration of the spell.
If the subject is prevented from obeying the lesser geas for a
whole day, he suffers a 2 penalty on each ability score.
Each day, another 2 penalty accumulates, up to a total of
8. Abilities are not reduced below 1. The ability penalties
end 1 day after the character resumes obeying the lesser geas.
A lesser geas (and all ability penalties) can be ended by
break enchantment, limited wish, remove curse, miracle, or wish.
Dispel magic does not affect a lesser geas.
