Type: Pact Magic
Source: Tome of Magic
You can expel a vestige to which you are bound before the duration of its pact with you has expired.
Prerequisite: Soul binding
Benefit: Once per day, you can attempt to expel a vestige to which you are bound. To do so, you must draw its seal and go through the entire process of summoning it again. If you succeed on the new binding check, you expel the vestige before it would normally leave you, and you can summon a different one to replace it if you wish. Regardless of your success or failure in expelling the vestige, you take a -10 penalty on your next binding check with any vestige, and apply the same penalty on your binding check the next time you summon the vestige you expelled.
Normal: A bound vestige does not leave you until 24 hours have passed since its summoning.
