Grasping Tentacles. Demogorgon can use a bonus action to make a bite, fling or tentacle attack against a target it has grappled.
Innate Spellcasting. Demogorgon’s spellcasting ability is Charisma (spell save DC 24, +16 to hit with spell attacks). Demogorgon can innately cast the following spells, requiring no material components:
At will:
detect magic, dispel magic, fear, fly, major image, telekinesis, wall of ice
3/day each:
contagion (flesh rot), charm monster
, evard's black tentacles, project image, teleport
1/day each:
feeblemind, plane shift (self only), time stop, weird
Legendary Resistance (3/Day). If Demogorgon fails a saving throw, he can choose to succeed instead.
Limited Magic Immunity. Unless Demogorgon wishes to be affected, it is immune to spells of 3rd level or lower. It has advantage on saving throws against all other spells and magical effects and any creature that makes a spell attack against Demogorgon has disadvantage on the attack roll.
Magic Weapons. Demogorgon’s weapon attacks are magical.
Maddening Gaze. When a creature that can see Demogorgon starts its turn within 120 feet of it, the creature must make a DC 18 Charisma saving throw if Demogorgon isn’t incapacitated and can see the creature. On a failed save, the target must roll a d10, suffering one of the following effects determined by the roll:
1-4. Beguiling Gaze. The target is stunned until the end of Demogorgon’s next turn or until Demogorgon is no longer within line of sight.
5-8. Insanity Gaze. The target suffers the effect of the confusion spell without making a saving throw. The effect lasts until the start of Demogorgon’s next turn. Demogorgon doesn’t need to concentrate on the spell.
9-10. Hypnotic Gaze. The target is charmed by Demogorgon until the end of Demogorgon’s next turn. While the target is charmed this way, Demogorgon can use an action, legendary action, or bonus action to take precise control of the target as in the spell
dominate monster.
Unless surprised, a creature can avert its eyes to avoid the saving throw at the start of its turn. If the creature does so, it can’t see Demogorgon until the start of its next turn, when it can avert its eyes again. If the creature looks at Demogorgon in the meantime, it must immediately make the save.
Necrotic Molt (Mythic Trait, recharges after a short or long rest). If Demogorgon is reduced to 0 hit points, it doesn’t die or fall unconscious. Instead, Demogorgon sheds its skin, all conditions and effects it is suffering end for it, it regains 496 hit points, all of its abilities recharge, and its space and the area within a 10-foot radius of it becomes difficult terrain for Medium and smaller creatures and any creature that ends its turn in the area takes 7 (2d6) necrotic damage.
Prince of Demons. Demogorgons attacks ignore all resistances of creatures CR or level 20 or below.
Additionally, any demon within 120 feet of Demogorgon must make a DC 20 Charisma saving throw at the start of each of its turn or suffer the effects of Demogorgon's hypnotic gaze.
Regeneration. If Demogorgon has at least 1 hit point, it regains 20 hit points at the start of it's turn.
Siege Monster. Demogorgon deals double damage to objects and structures.
Teleport. Demogorgon can use a bonus action to magically teleport up to 120 feet to an unoccupied space it can see.
Two Heads. Demogorgon has advantage on saving throws against being blinded, deafened, stunned, and knocked unconscious.
ACTIONS
Multiattack. Demogorgon makes two attacks: any combination of bite, fling, tail, and tentacle attacks.
Tentacle. Melee Weapon Attack. +17 to hit, reach 15 ft., one target.
Hit. 22 (3d8 + 9) bludgeoning damage plus 33 (6d10) necrotic damage and if the target is a Medium or smaller creature it must make a DC 25 Strength saving throw or be grappled. A creature grappled in this way is also restrained. Additionally, the target's hit point maximum is reduced by an amount equal to the necrotic damage taken. The reduction lasts until the target finishes a Long Rest. The target dies if this Effect reduces its hit point maximum to 0.
Bite. Melee Weapon Attack. +17 to hit, reach 5 ft., one grappled, charmed, or incapacitated creature.
Hit. 28 (3d12 + 9) piercing damage or 61 (8d12 +9) damage on a critical hit. This attack scores a critical hit on a roll of 18 - 20.

Hit: 19 (3d6 + 9) piercing damage and the target must make a DC 24 Constitution saving throw or gain one level of exhaustion on a failure or be poisoned on a success. These effects remain until the target takes a short or long rest, removing 1 level of exhaustion or the poisoned condition on a short rest or 4 levels for a long rest.
Fling. One Medium or smaller object or creature held or grappled by Demogorgon is thrown up to 120 ft in a direction of its choosing. The target must make a DC 25 Dexterity saving throw or take 3 (1d6) bludgeoning damage for every 10 feet it was thrown and knocked prone on a failure, or half as much damage one a success. If the target is thrown at another creature, that creature must succeed on a DC 25 Dexterity saving throw or take the same damage and be knocked prone.

Demogorgon as a Mythic Encounter
Demogorgon is a terrifying opponent for high-level characters, but if you can increase the insanity of the encounter by using the Necrotic Molt trait. When this happens, Demogorgon rejuvenates and then can use its mythic actions when it uses a legendary action.
Read or paraphrase the following text when Demogorgon uses its Necrotic Molt trait:
The Demon Prince's skin cracks and falls to the ground in viscous clumps of ichor covered hide and scales. Standing among the gore is a resplendent Demogorgon of untarnished scales and hide.
Fighting Demogorgon as a mythic encounter is equivalent to taking on two CR 28 creatures in one encounter. Award a party 240,000 XP for defeating Demogorgon after it uses Necrotic Molt.
