Alert The Tarrasque gains a +6 to initiative rolls.

Augmented critical The Tarrasque will score a critical hit on an attack roll of 18-20.

Elder of Annihilation The Tarrasque ignores the damage resistances of other creatures.

Surefooted The Tarrasque has advantage on attacks that would knock it prone.

Trample When the Tarrasque enters any enemy's space for the first time on a turn, the enemy must succeed on a DC 19 Dexterity saving throw or take 24 (5d12+10) bludgeoning damage and be knocked prone.

Earthbound Aura Creatures with a fly speed within 1 mile of the Tarrasque have their fly speed reduced to 0. If a creature is in midair when it becomes affected by Earthbind Aura, it falls at a rate of 60 feet per round until it reaches the ground.

Mutate The Tarrasque will lay still for 1d12 rounds after being defeated. After the 1d12 rounds have ended, it will have mutated into it's second form

Reflective Carapace Any time the Tarrasque is targeted by a magic missile spell, a line spell, or a spell that requires a ranged attack roll, roll a d12. On a 1 to 10, the tarrasque is unaffected. On an 11 or 12, the tarrasque is unaffected, and the effect is reflected back at the caster as though it originated from the Tarrasque, turning the caster into the target.

Regeneration The Tarrasque will regenerate 50 hit points at the start of it's turn as long as it has 1 hit point left. This effect is doubled in it's second form.


Bite: +20 to hit, reach 15 ft., one target. Hit: 38 (4d12 + 10) piercing damage.If the target is a creature, it is grappled (escape DC 20). Until this grapple ends, the target is restrained, and the tarrasque can't bite another target.

Horns: +20 to hit, reach 15 ft., one target. Hit 40 (5d12 +10) piercing damage.

Claws: +20 to hit, reach 20 ft., one target. Hit 40 (5d12 +10) piercing damage.

Swallow: The tarrasque makes one bite attack against a Large 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 tarrasque, and it takes 56 (16d6) acid damage at the start of each of the tarrasque's turns. If the Tarrasque takes 60 damage or more on a single turn from a creature inside it, the Tarrasque must succeed on a DC 20 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 Tarrasque. If the Tarrasque dies, a swallowed creature is no longer restrained by it and can escape from the corpse by using 35 feet of movement, exiting prone.

Rock Throw: The Tarrasque picks up a large rock and throws it. +20 to hit. Range 400/1000 ft., one target. Hit: 38 (4d12 +10) bludgeoning damage.

Frightful Presence: Each creature of the Tarrasque's choice within 120 feet of it and aware of it must succeed on a DC 17 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 Tarrasque 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 Tarrasque's Frightful Presence for the next 24 hours.

Multi-Attack: The Tarrasque 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. Alternatively, it makes three rock attacks.

Tail Sweep: +24 to hit, reach 30 ft., eight targets. Hit 50 (6d12 +10) bludgeoning damage.

Shockwave: The Tarrasque Jumps 20 ft into the air and slams down onto the ground and all creatures and structures on the ground within 100 feet of the Tarrasque are affected as they would be by the earthquake spell (save DC 20. This Attack requires five rounds to recharge.).

Energy Breath: The Tarrasque spew a mix of Necrotic and Radiant energy from it's mouth in a 140 ft cone. +20 to hit, range 1000 ft., two targets. Hit: 124 (12d12 +10) Necrotic or Radiant damage (DM's choice. This attack also requires eight rounds to recharge)

This was the "Final Boss" of my first campaign and I wanted to share it so other DM's could use it. The Mega Tarrasque is the beast that was created from a resurrected, and modified corpse of a Tarrasque. This Monstrosity is bigger and stronger than the normal Tarrasque, and it is being used to destroy entire civilizations and kill off races.
