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.
I mean it is strong sure, but the fact that any ancient dragon with a breath weapon other than poison or fire could easily dunk on the Tarrasque... makes me kinda wonder. If you truly want chaos and destruction look up The True Tarrasque. Now THAT is true chaos and destruction.
The minimum amount of damage is 14 and the bonus to the Hit/DC alone will breach any AC
oh this is ganna be fun. im making this my lvl 1 party's second encounter. they wont fight it, unless they wake it up-
dragon boi with no wings
Absolutely
Does anybody support the idea of a "Mecha-tarrasque" that has CANNONS so it can use ranged attacks and ROCKETS so it can fly?
even a lvl. 1 aaraocka with a magical ranged weapon and almost infinite ammo can beat it.
DEFINITELY Tiamat. Tiamat just flies out of reach and uses ranged attacks to beat it.
They can, just not in one turn, since they can move 25 ft. in one turn and 5 ft. in the other.
A player can have strength 30 with the most powerful of the Belts of Giant Strength
Wow, this thing has less health than my Abyssal Dragon
Also this thing is immortal, and you have to use the 9th level spell wish to kill it.
Why not just make up a creature that can use wish, and have it wish that all the players die?
One fairly common modification I've heard is people letting it rip up chunks of the ground or buildings if it has any within reach and hurl them as a ranged attack. Something like a stronger version of a giant's rock attack.
Alternatively: Demogorgon. While players aren't going to be able to control that situation I very much like the idea of seeing what The Prince Of Demons could get up to with an incapacitated tarrasque.
For all those asking if the Tarrasque can beat Tiamat, here you go.
Tiamat has a fly speed of 120 ft. she could eaisly outpace a Tarrasque on its best of days.
Tiamat has ranged attacks that deal cold, acid, and lightning damage, which aren't affected by the Tarrasque's reflective carapace. She can easily just breath weapon the Tarrasque to death while she flies safely out of reach.
Tiamat's weapon attacks are magical, getting around the Tarrasque's immunity.
If all that isn't enough to convince you that Tiamat would find the Tarrasque a light snack, then the fact that she has immunity to acid damage and bludgeoning, piercing, and slashing damage from non-magical attacks (which covers all of the Tarrasque's attacks) should be enough. The Tarrasque stands no chance against Tiamat.
Literally anything with a flying speed kills this thing.
Not as OP as people think, an Aarokocra commoner with an alchemy jug could solo this thing. Not to mention how little damage it does relatively, how slow it is, and how little range it has. The only time this causes a challenge is if some idiot decides to try to fight it on open flat ground (Even then if they have 40 feet of movement or more and literally any way to do damage to it they're good) and is under level 10, or has some kind of time constraint. A level 1 party could beat this thing if they had anything to bypass the damage immunities.
How unearthly boring
The Aarokocra wouldn't be able to do any damage to the Tarrasque with a bow, but spellcasting or dropping acid would be a different story. The aarokocra can fly up 50 feet EVERY TURN, so they can easily get 100 feet up and just bombard the Tarrasque from there. The thing is, they'd need 338 flasks of acid on average
Just throwing it out there, but if the Tarrasque uses all its legendary actions for movement, it effectively has a 100 ft move speed.
