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.
Pathetic compared to the new Tiamat and bahamut or even just a Greatwyrm or ancient Dragon turtle
...why
The legendary Tarasque "was described as having a lion-like head, a body protected by turtle-like carapaces, six feet with bear-like claws, and a scaly tail like a serpent's ... and issued poison breath". I'd add 5 more AC, a couple extra claw attacks, immutable form, and a legendary action of breathing a Cloudkill effect. If you still have problems with flying archers trying to plink away at it forever without risk, give it a Godzilla-like breath weapon to do 10d10 fire plus 10d10 force damage in a 10 foot wide and 300 foot long line and regeneration of 50 per round.
to kill use a peasant rail gun
Do you think a level 20 can succeed against this titan monstrosity
And how is it unaligned HOW
This thing is unstoppable
I can shift into this as a level 20 druid in my campaign
A world destroyer by itself, I wonder if more than 1 showed up at once.
I simulated a battle between the Tarrasque and a Level 9 Party.
They consisted of 4 Kobold Eldritch Knight Archers, with Sharpshooter and Crossbow Expert, on Horses with Longstrider, Self Casting Magic Weapon
And a Multiclassed Sorcerer-Cleric who casts Bless and the Longstriders
The Horses could run a 140 feet in a round which is equal to the Tarrasque's Dash plus 3 Legendary Actions of Move so they Ready their movement to keep out of reach.
They waited until night - to get rid of the Sunlight Sensitivity
The Sorcerer-Cleric took his Pre-casted Find Familiar of a Lizards and stick it to the Tarrasque- giving them Pack Tactics - I doubt a Gargantuan creature could even see a Tiny one.
The Attacks looked something like this:
Attack Roll 2d20 + 1d4(Bless) + 6(Dex-4 + PB-4 + Archery-2 + Magic Weapon-1- Sharpshooter-5) Damage 1d6 +15
12 Attacks per Round
40% Success Rate Against the Tarrasque's AC
It took only 6 rounds of combat to kill!
And people say the Tarrasque is good.
Level 9 party - without Magic Items - 6 rounds!!!
This thing gives a whole new meaning to the term "OP."
Probably still a TPK before the third or fourth round.
An entire party of 20th-level characters, one from each of the 12 classes, have each received every single boon in existence and been given as many legendary items as they can possibly carry comfortably. The tarrasque kills them all in one swipe.
That's pretty much how OP this freaking dude is, he's like Super Godzilla if he were a few times bigger and stronger and his Atomic Breath was at the level of a freaking IBM from three thousand years in the future. He has such ridiculous power that the only more powerful being in everything except homebrew would be Tiamut, and she's literally the goddess of dragons. I mean, the game is called Dungeons and Dragons, for Tiamut's sake!
And, of course, this is puny compared to earlier editions.
That feels like an out of place Highlander reference.
Hold it, how the frick do you transform into a freaking tarrasque?
Apparently not as op as everyone's saying, according to LordLegend
Who would win, a tarrasque or Tiamat? She may be the only won who could pose a challenge to this beast. And maybe Bahamut and Asmodeus but we don’t get to see their stat sheets.
You can kill it with 1 level 1 character with a +1 bow, ring of spell storage(Greater Steed) and horse shoes of speed. Yes, everything is cheesable if you don't DM them correctly.
A Tarrasque can also just disappear into the ground and show up anywhere else in the world it wants, and it should be generally ignoring the party as they shouldn't be relative to its goals. The party can provide the DPR to kill it, but can they get to it and deal with it faster than it can destroy a city? Are they going to ignore saving dozens of people from falling debris with a turn so they can min/max their damage? Can they save the castle walls from collapsing?
If the game has a CR 30 creature to just show up and be a DPR contest, you aren't really utilizing it to its potential.
D&D Godzilla every one
The point was that you could do it with a low level party WITHOUT magic items.
Of course you could give them scrolls of wish and any other OP item or even just a +3 weapon but that's not the point.
The point is that its a bunch of vanilla low level characters way out of their CR league that can do it in 6 rounds (36 seconds in game) without simply giving them OP magic weapons.
It's funny how half the people here are saying that it's Godzilla and you need Level 20 characters with every magic item to stand a chance.
And the other half is saying how it's just a weak completely melee based monster that can be easily beat by a low level party.
