Vestige Versatility

Paragon Tier
Prerequisite: 11th level, warlock, Vestige Pact class feature
Benefit: Whenever you are allowed to change your vestige, you can choose to have two active vestiges instead of one. When your pact boon is triggered or when you use your eyes of the vestige power, you choose which vestige's benefit applies.
If you would ordinarily be required to choose between the two primary vestiges, this feat enables you to have both of them as active vestiges. If you use a daily attack power that gives you access to a new vestige, you can choose for that daily power vestige to replace either of your two active vestiges.
