Binding of the Wills

Willingly or not, you are more literally bound to your Patron than other Warlocks.  Either partially or more wholly, you and your patron are "one".  At the risk of losing themselves or having lost portions of themselves already, Warlocks with this closeness undoubtedly possess greater power.

• Gain one extra Pact Magic Slot.  This slot acts as a normal Pact Magic Slot.
• Your Patron sometimes has more command over your will, actions, speech and/or thoughts than you do.  Work with your DM to determine how, and the frequency that this will manifest.
