Gift of the Protectors

Prerequisite: Level 9+ Warlock, Pact of the Tome Invocation
A new page appears in your Book of Shadows when you conjure it. With your permission, a creature can take an action to write its name on that page, which can contain a number of names equal to your Charisma modifier (minimum of one name).
When any creature whose name is on the page is reduced to 0 Hit Points but not killed outright, the creature magically drops to 1 Hit Point instead. Once this magic is triggered, no creature can benefit from it until you finish a Long Rest.
As a Magic action, you can erase a name on the page by touching it.
