Baron Nashor

Multiheaded: The Baron Nashor has three heads. While it has more than one head, the Baron Nashor has advantage on saving throws against being blinded, charmed, deafened, frightened, stunned, and knocked unconscious. If the Baron Nashor takes 60 or more damage in a single turn, one of its smaller heads dies. If all of its smaller heads die, it loses the multiheaded trait.

Regeneration: The Baron Nashor regains 20 hit points at the start of its turn. If the Baron Nashor takes radiant or fire damage, this trait doesn't function at the start of the Baron Nashor's next turn. The Baron Nashor dies only if it starts its turn with 0 hit points and doesn't regenerate.

Multiattack: The Baron Nashor makes three attacks: one with its bite and two with its grapple hands. It can replace any attack with the use of Territorial Roar if it is in Territorial form, or Foresight if it is in All-Seeing form.

Bite: Melee Weapon Attack: +17 to hit, reach 15 ft., one target. Hit: 38 (4d12 + 10) piercing damage plus 18 (4d8) acid damage. If the target is a Large or smaller creature, it is swallowed by the Baron Nashor. A swallowed creature is blinded and restrained, it has total cover against attacks and other effects outside the Baron Nashor, and it takes 21 (6d6) acid damage at the start of each of the Baron Nashor's turns. If the Baron Nashor takes 30 damage or more on a single turn from a creature inside it, the Baron Nashor must succeed on a DC 25 Constitution saving throw at the end of that turn or regurgitate the swallowed creature, which falls prone in a space within 10 feet of the Baron Nashor. If the Baron Nashor dies, a swallowed creature is no longer restrained by it and can escape from the corpse using 15 feet of movement, exiting prone.

Grapple: Melee Weapon Attack: +17 to hit, reach 10 ft., one target. Hit: 32 (4d10 + 10) bludgeoning damage, and the target is grappled (escape DC 20). The Baron Nashor has six grapple hands, each of which can grapple one target.

Territorial Roar (Recharge 5-6): The Baron Nashor emits a devastating roar if it is in Territorial form. All creatures within 120 feet of the Baron Nashor that can hear it must succeed on a DC 18 Wisdom saving throw or become frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, with disadvantage if the Baron Nashor is within line of sight, ending the effect on itself on a success.

Foresight (Recharge 6): If Baron Nashor is in All-Seeing Form, the third eye on the forehead of its main head glows with a preternatural light as an action, allowing the Baron Nashor to anticipate its enemies' moves. For 1 minute, any attack roll made against it has disadvantage, and it makes attack rolls, ability checks, and saving throws with advantage. This effect ends early if the Baron Nashor is incapacitated or if its third eye is somehow blinded or closed.

Charge: If the Baron Nashor is in Hunting form and moves at least 20 feet straight toward a target and then hits it with a gore attack on the same turn, the target takes an extra 22 (4d10) piercing damage. If the target is a creature, it must succeed on a DC 25 Strength saving throw or be knocked prone.

Forms: The Baron Nashor has three forms that it can switch between: Territorial, All-Seeing, and Hunting. It can switch between these forms using a bonus action, allowing it to use the specialized form abilities outline in the actions section.
