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

Magic Resistance. The Tyrant has advantage on saving throws against spells and other magical effects.

Tyrant's Carapace. Any time the Tyrant is targeted by a magic missile spell, a line spell, or a spell that requires a ranged attack roll, roll a d8. On a 1 or 2, the Tyrant takes 1/2 damage and halves any effect's duration. On a 3 to 7, the Tyrant is unaffected, and heals 25 HP. On an 8, the Tyrant is unaffected, and the effect is reflected back at the caster as though it originated from the Tyrant, turning the caster into the target.

Siege Monster. The Tyrant deals double damage to objects and structures.

Tyrant's Regeneration. The Tyrant has enhanced regenerative capabilities, healing 30 6d8+3 health at the start of each of its turns.

Actions

Multiattack. The Tyrant can use its Frightful Presence. It then makes five attacks: one with its bite, two with its claws, one with its horns, and one with its tail. It can use its Swallow instead of its bite.

Bite. Melee Weapon Attack: +12 to hit, reach 10 ft., one target. Hit: 21 (3d10+5) piercing damage. If the target is a creature, it is grappled (escape DC 17). Until this grapple ends, the target is restrained, and the Tyrant can't bite another target.

Claw. Melee Weapon Attack: +12 to hit, reach 15 ft., one target. Hit: 19 (3d6+5) slashing damage.

Horns. Melee Weapon Attack: +12 to hit, reach 10 ft., one target. Hit: 15 (3d8+5) piercing damage.

Tail. Melee Weapon Attack: +12 to hit, reach 20 ft., one target. Hit: 12 (3d4+5) bludgeoning damage. If the target is a creature, it must succeed on a DC 17 Strength saving throw or be knocked prone.

Frightful Presence. Each creature of the Tyrant's choice within 120 feet of it and aware of it must succeed on a DC 16 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 Tyrant is within line of sight, ending the effect on itself on a success. If a creature's saving throw Is successful or the effect ends for it, the creature is immune to the Tyrant's Frightful Presence for the next 24 hours.

Swallow. The Tyrant makes one bite attack against a Medium or smaller creature it is grappling. If the attack hits, the target takes the bite's damage, the target is swallowed, and the grapple ends. While swallowed, the creature is blinded and restrained, it has total cover against attacks and other effects outside the Tyrant, and it takes 35 (10d6) acid damage at the start of each of the Tyrant's turns. If the Tyrant takes 40 damage or more on a single turn from a creature inside it, the Tyrant must succeed on a DC 27 Constitution saving throw at the end of that turn or regurgitate all swallowed creatures, which fall prone in a space within 10 feet of the Tyrant. If the Tyrant dies, a swallowed creature is no longer restrained by it and can escape from the corpse by using 20 feet of movement, exiting prone.
