Pact of the Tome. Your patron gives you a grimoire called a Book of Shadows that grants you additional cantrips that don't count against your number of cantrips known. If you lose the book, you can perform a 1-hour ceremony to receive a replacement during a short or long rest.

Phantasmic forgetfulness. Your link to the spirit world allows you to cast Phantom Deja Vu without using a spell slot. Upon taking ranged damage, you fix the creature that damaged you with a piercing stare. The creature must make a Wisdom saving throw (13) and takes 1d4 psychic damage on a failed save. If the first saving throw is a fail, at the beginning of the creatures next turn it must make another Wisdom saving throw (13). Upon a second failed save, the creature makes it's first attack as normal, then must use it's bonus action to make an identical attack against a party member of their choice. The bonus attack does not cost any spell slots, and requires a fresh set of dice throws.
