The Revised Tarrasque

[SyntheticHuman]

So, I think a lot of people share my opinion that for something that, at least for a while, was ostensibly the hardest monster in the game, the Tarrasque is a tad bit underwhelming. With a total lack of ranged options, it can easily be countered by flying creatures or coward strategies, and any dragon would kick its tail. In addition, with the new Mythic rules, it has definitely fallen behind.
Here, I present a new homebrewed version of the Tarrasque that I've made, specifically engineered to mess up a party of level 20 adventurers who think they're too cool for school. I've made it even harder to magic your way out of the fight, added a roar that pulls triple duty as playing into its siege monster side, its antimagic side, and gives it an option to counter flying creatures. I've also added mythic options for the fight, making it so that after it dies the first time, it returns with very few hit points but a higher AC and extremely damaging primal flavored mythic actions. Let me know if you have any feedback, I do want to use this against some players in a campaign I'm running and I want to make sure it actually works.
Now on version 2.6!

I notice its max range is 60'.
That means it can still be taken down by a level one Cleric with Flight.

I made my own version (https://forums.giantitp.com/showthread.php?542991-Big-T-Revised), back in 2017. Feel free to mine it for ideas!

Edit: My bad, he's immune to cantrips. Warlocks are big sad.

So you'd need a LOT of arrows and a magic bow.

Edit the II: Actually, a Druid can manage it from level one without any special items, if they're of a flying race. Had a partner point that trick out to me.

Thanks for the idea mine, I'll definitely use that.
Also, Warlocks are probably already sad when fighting a tarrasque with the base rules- Any spell that uses a ranged attack is ineffective, and has a 17% chance of getting reflected back on the user.
I don't really want to extend the range of its roars as that would probably get a tad bit ridiculous. I think I might change its frightening presence into some sort of baleful gaze that kills your speeds.

Edit: Big fan of the minor damage immunity, I'm stealing that.
