Legendary Resistance (3/Day). If the tarrasque fails a saving throw, it can choose to succeed instead.
Magic Resistance. The tarrasque has advantage on saving throws against spells and other magical effects.
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 d6. On a 1 to 5, the tarrasque is unaffected. On a 6, 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.
Siege Monster. The tarrasque deals double damage to objects and structures.
Multiattack. 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.
Bite. Melee Weapon Attack: +19 to hit, reach 10 ft., one target. Hit: 36 (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.
Claw. Melee Weapon Attack: +19 to hit, reach 15ft., one target. Hit: 28 (4d8 + 10) slashing damage.
Horns. Melee Weapon Attack: +19 to hit, reach 10ft., one target. Hit: 32 (4d10 + 10) piercing damage.
Tail. Melee Weapon Attack: +19 to hit, reach 20ft., one target. Hit: 24 (4d6 + 10) bludgeoning damage. If the target is a creature, it must succeed on a DC 20 Strength saving throw or be knocked prone.
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.
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 30 feet of movement, exiting prone.
The tarrasque 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. The tarrasque regains spent legendary actions at the start of its turn.
Attack. The tarrasque makes one claw attack or tail attack.
Move. The tarrasque moves up to half its speed.
Chomp (Costs 2 Actions). The tarrasque makes one bite attack or uses its Swallow.
sheer Power
Absolute unit
the true king of the beast
If I was a DM, I would use this as a final boss for my campagin once all players, minimum of 7, have reached level 20 and have atleast one magical weapon that is enhanced to +3 per person.
They will love my one shot....
When in desperate need of a TPK, accept no substitute.
That's more or less how I reacted to this. The way I just described it to a friend is "The D&D embodiment of NOPE" and "The more formal version of Rocks Fall, Everybody Dies".
If I were to describe a Tarrasque, I would be calling it away more overpowered version of Godzilla.
Overpowered melee locked Godzilla
Yeah like that
niiiiiiiiiice
I am going to kill all my friends with this thing
undefeatable
that's one angry armadillo
I wonder what will happen when a Level 1 character fights it...hmmm...........................
Death on purpose because if your DM did this to a Lv1 Character they are dead. period. 😅

A monster God
It is a melee monster par excellence, but it has no ranged attacks, can't regenerate damage, and takes full damage from magical weapon attacks. Flying and/or ranged combatants (of the appropriate level with magical bows/crossbows) would pick it apart with little difficulty. Casters using Dex-focused AOEs that aren't fire or poison can wreak havoc, too (once they removed the 3 legendary saves). I would actually beef it up and give it very strong regeneration (like the tarrasque of old has) and likely allow its claws and teeth to crit on 19-20 if not 18-20. It is supposed to be one of the most feared (if not the most feared) monster of all. Even Godzilla has his atomic breath.
my 15th level group probably could not fight this...
The king of the beasts
like Godzilla, but more deadly
