The Ink of the Patron

Your vial of ink begins to glow with the power of your patron.

Beginning at 10th level, you can call on your patron to intervene on your behalf when your need is great.

You spend 1 minute inscribing the request into your tome with the newly empowered ink.

Imploring your pateon's aid requires you to use your action. Describe the assistance you seek, and roll percentile dice. If you roll a number equal to or lower than your Warlock level, your patron intervenes. The DM chooses the nature of the intervention. If your patron intervenes, you can't use this feature again for 7 days. Otherwise, you can use it again after you finish a Long Rest.

At 20th level, your call for intervention succeeds automatically, no roll required.
