Aberrant Origin. The aberrant patron ignores the effects of its own spells, and is immune to damage from its own spells.

Innate Spellcasting. The aberrant patron's spellcasting ability is Charisma (spell save DC 15, +7 to hit with spell attacks). It can innately cast the following spells, requiring no components:
 At will: arms of Hadar
1/day: hunger of Hadar

Patron Features. The aberrant patron gains the following warlock class features, if their warlock is of a level to have them: awakened mind, entropic ward, thought shield, and create thrall. If these features have limited uses, the aberrant patron's uses are counted separately from the warlock's.

Multiattack. The aberrant patron makes one claw attack and one tentacle attack.

Claw. Melee Weapon Attack: +6 to hit, reach 5ft., one target. Hit: 7 (1d8 + 3) slashing damage.

Tentacle. Melee Weapon Attack: +5 to hit, reach 15ft., one target. Hit: 9 (2d6 + 2) bludgeoning damage and 3 (1d6) psychic damage.

Psychic Assault (Recharge 5-6). The aberrant patron selects a target it can see within 60ft. The target must make a DC 15 Charisma saving throw, and takes 28 (8d6) psychic damage on a failed saving throw, or half as much on a successful one.
