At the basic level of effect, an
incantation using the
compel seed must be worded in such a manner as to make the activity sound reasonable. Asking the creature to stab itself, throw itself onto a spear, immolate itself, or do some other obviously harmful act automatically negates the effect. However, urging a
dragon to stop attacking your friends so that everyone could jointly assault a mob safehouse elsewhere is a reasonable use of the
incantation's power.
The compelled course of activity can continue for the entire
duration, such as in the case of the
dragon mentioned above. If the compelled activity can be completed in a shorter time, the
incantation ends when the subject finishes what he was asked to do. You can instead specify conditions that will trigger a special activity during the
duration. For example, you might compel a rock star to give her the first panhandler she meets a ride in her limo. If the condition is not met before the
incantation using this seed expires, the activity is not performed.
