Chaos Incarnate, Malagorath

Legendary Resistance (3/Day). If Malagorath fails a saving throw, it can choose to succeed instead

Magic Resistance: Advantage on saving throws against spells and other magical effects.

Innate Spellcasting: Spellcasting ability is Charisma (spell save DC 22). It can innately cast the following spells, requiring no material components:

At will: counterspell, dispel magic, mage hand

3/day each: chaos bolt, confusion, dispel magic (at 4th level), dominate person, teleport

1/day each: cone of cold, dominate monster, teleportation circle

Multiattack: Malagorath makes three attacks, one with its bite, and two with its tentacles.

Bite. Melee Weapon Attack, +14 to hit, reach 10ft, one target. Hit 21 (2d10+7) Piercing Damage

Tentacle. Melee Weapon Attack: +14 to hit, reach 15 ft., one target. Hit: 19 (3d8 + 7) bludgeoning damage plus 14 (4d6) psychic damage. If the target is a creature, it must succeed on a DC 22 Wisdom saving throw or be stunned until the end of its next turn.

Chaos Blast (Recharge 5–6). Chaos Incarnate releases a blast of chaotic energy in a 60-foot cone. Each creature in that area must make a DC 22 Dexterity saving throw, taking 45 (10d8) force damage and 45 (10d8) psychic damage on a failed save, or half as much damage on a successful one. Additionally, on a failed save, creatures are pushed 20 feet away from Chaos Incarnate and are stunned until the end of their next turn.

Warp Reality (1/Day). Malagorath can twist the fabric of reality in a 120-foot radius centered on himself. For 1 minute, the area becomes a swirling vortex of chaotic energy. During this time, all creatures in the area must make a DC 22 Wisdom saving throw at the start of their turns. On a failed save, they roll on the Wild Magic Surge table (PHB p. 104) and suffer the effects immediately. Malagorath can choose to be unaffected by this ability

Unleash Chaos. Malagorath can cause an object or surface within 60 feet to erupt with chaotic energy. Each creature within 10 feet of the point must succeed on a DC 22 Dexterity saving throw or take 14 (4d6) force damage and be knocked prone.

Frenzied Assault. Malagorath makes one Tentacle attack.

Chaotic Deflection. When Malagorath is hit by a ranged attack, he can use his reaction to impose disadvantage on the attack roll, potentially causing it to miss.

Retributive Strike. When a creature within 5 feet of Malagorath hits him with a melee attack, he can use his reaction to make a Bite attack against that creature.

Legendary Actions. Chaos Incarnate can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature's turn. Chaos Incarnate regains spent legendary actions at the start of its turn.

• Chaos Strike. Chaos Incarnate makes one melee attack.
• Twisting Reality (Costs 2 Actions). Chaos Incarnate casts confusion or dispel magic (at 4th level).
• Chaotic Aura (Costs 3 Actions). Chaos Incarnate unleashes a burst of chaotic energy in a 30-foot radius centered on itself. Each creature in that area must make a DC 22 Wisdom saving throw, taking 21 (6d6) psychic damage on a failed save, or half as much damage on a successful one.
