Eldritch Fanatic

Your loyalty to your patron is beyond fanatical, and they have rewarded you for this service. You gain the following benefits: You gain +1 to Charisma up to a maximum of 20.

You gain a first level Warlock spell slot that can be used for any single first level Warlock spell of your choice. If you already have Warlock spell slots, you gain one additional one that functions normally.

Whenever you must make a saving throw, you gain a bonus to the saving throw equal to your Charisma modifier (with a minimum bonus of +1). You must be conscious to receive this bonus.
