Book of Vile Arts
Prerequisites: Pact of the Tome, 7th level
You can cast a warlock spell you know once without using a warlock spell slot. When you do so, you take 1d4 necrotic damage per level of the spell slot expended.
Once you use this invocation, you can't do so again until you finish a short or long rest.
Eldritch Harmony
Prerequisites: Pact of the Tome, 7th level
When you use your action to cast a cantrip gained from your pact tome, you can make one weapon attack as a bonus action.
Eldritch Prison
Prerequisites: Pact of the Chain, 7th level
When you reduce a creature of CR 1 or lower to 0 hit points, you can use your reaction to attempt to imprison the creature. The target must make a Charisma saving throw against your warlock spell save DC. A creature that is not native to the Material Plane has disadvantage on this saving throw, and humanoid creatures have advantage instead. On a failed save, the target disappears into a harmless demiplane, suspended in time.
While you have a creature imprisoned in this way, you can use your bonus action to summon the creature to an unoccupied space within 30 feet of you. You can use another bonus action to have the disappear to the harmless demiplane again. An imprisoned creature regards you as an ally, although it acts independently of you. It rolls its own initiative in combat and follows commands given to it by you or creatures you designate. When you finish a short or long rest, the imprisoned creature receives the same benefits.

When the imprisoned creature is reduced to 0 hit points, it disappears to the harmless demiplane. Until you finish a long rest, the imprisoned creature cannot be summoned again. You can only have one creature imprisoned at a time. If you imprison another creature using this invocation, the previously imprisoned creature appears in an unoccupied space within 30 feet of you and is no longer bound to you.
