Cheez-it can use an action to touch a willing creature and protect it from being charmed. Once protected, the creature can repeat the saving throw against being charmed at the end of each of its turns, ending the effect on a success. The protection lasts until Cheez-it uses this feature again or finishes a short or long rest.

Cheez-it fires a beam of crackling otherworldly energy. He makes a ranged spell attack using his spell attack bonus. On a hit, the target takes 1d10 + 4 force damage.

Cheez-it curses a creature he can see within range. The target takes an extra 1d6 necrotic damage whenever Cheez-it hits it with an attack, and Cheez-it gains advantage on ability checks made to find it.

A defensive shell of icy spectral energy surrounds Cheez-it, granting 5 temporary hit points. A creature that hits him with a melee attack while those temporary hit points remain takes 5 cold damage.

Cheez-it whispers a fragment of impossible knowledge into a creature's mind. On a failed Wisdom saving throw, the target takes 3d6 psychic damage and must immediately use its reaction, if available, to move as far as its speed allows away from him.

Cheez-it teleports up to 30 feet to an unoccupied space he can see.

Cheez-it magically influences a humanoid he can see. On a failed Wisdom saving throw, the target is charmed for up to 8 hours and regards Cheez-it as a friendly acquaintance.

Cheez-it opens a sphere of black, starless hunger at a point within range. The area becomes difficult terrain, and creatures inside take 5d6 cold damage on a failed Constitution saving throw, or half as much on a success.

Cheez-it interrupts a creature in the process of casting a spell. If the interrupted spell is 3rd level or lower, it fails automatically. Higher-level spells require a spellcasting ability check.

Cheez-it can cast warlock spells using Charisma as his spellcasting ability. He knows three cantrips and seven warlock spells, and he can replace one known warlock spell whenever he gains a warlock level.

When Cheez-it scores a critical hit with an attack against a creature, he can choose that creature and any other creatures of his choice within 30 feet of it that can hear him. Each chosen creature is frightened of him until the end of his next turn.

Cheez-it learns eldritch invocations that grant him specialized magical abilities. His invocations are Agonizing Blast, Mask of Many Faces, and Misty Visions.

Cheez-it gains a pact boon from his patron. He has chosen Pact of the Chain and can cast Find Familiar as a ritual. His familiar is a spectral, bat-winged pseudodragon named Crumb, which resembles a tiny dragon made of smoke and blue-white embers.

Cheez-it's patron spells include Dissonant Whispers, Tasha's Hideous Laughter, Detect Thoughts, Phantasmal Force, Clairvoyance, and Sending. These spells are added to the warlock spell list available to him, though they are not automatically known.

Cheez-it can find a place to hide, rest, or recuperate among common folk, who are willing to shield him from the law or those who pursue him. They will also share food and simple lodging with him, though they will not risk their lives for him.
