Ah! Tarrasque!

[smilinggm]

You know it sounds like to me that Laughing Boy is not a summoner but a very impressive illusionist. It is my bet that the arena battles that you witnessed were very large illusions designed to ammuse you and the crowds. Now back to the sleeping tarrasque. It is probalby real. If LB is dropping illusions of a tarrasque he had to get the image from somewhere. From this point forward I would prepaire my self against the tarrasque and any possible illusions that LB may or may not be dropping.
A fiew other possible tricks:
Place on the Big T a couple scarabs of death. The bloody things will not kill him but they could drop him into negative hp. Then it will be either a properly worded wish spell to keep it down, or planeshift/gate to some where there are fiew major powers to deal with. The inner planes are probably best. Again I like dropping him off on the Positive Material plane. Very fiew powers live there, NO chance of an undead tarrasque and due to the nature of the place even if does keep regenerating it will just keep exploding every couple of hours. This should keep it busy for a long time.
A necklass of strangulation could also do the same trick (If you could get it around its neck that is)
I can not remeber where I saw this but I rember seeing a spell that creats a temproary sphere of annihilation. If you can cast that puppy problem solved. for both Big T and LB. (this may have been a 2e spell the more that I think about it but it has probalbly been converted.)

Good Luck

Create an illusion of a Tarrasque, have it "attack you", and then kill it. Maybe the Evil Ruler won't bother looking into the cave and seeing the real one. Or if he does, cast dimensional anchor and wake the Tarrasque. Once it starts attacking him, join in on the fun.

The problem isn't the tarrasque, it's soundly asleep and with the proper protections could be asleep for a long time.

The problem is a monarch that shouldn't be. Using rampaging monsters to play games, with innocents trampled in the process, is not something a true monarch should do.

If he wants to play his game, and you can neither stop him nor the tarrasque, why play along?
Try instead to save the villagers and townsmen the Tarrasque will be threatening.

And paint the monarch's Royal Mage Tower with some red and white to make it look like a candycane, and use magic mouth to make it yell "I'm a tarrasque pinata" over and over again.

I'm BRILLIANT!

Darkness helped a bit too with this idea.

Cast Fox's Cunning on the Tarrasque. Or, if you don't think you can get through its SR, put a Headband of Intellect on it. Or just keep trying.

You now have a sentient Tarrasque.

Now, cast Tongues on it. Which doesn't bother with SR, by the way, so just cast as you wish.

Now, it is smart enough and capable of understanding you.

Got someone with a good diplomacy score? Take some time, talk it into being helpful to you. Maybe have it eat the guy who likes to screw around with creatures beyond the ken of mortal man.

Party Faceman: "Esteemed Mr. Tarrasque Esquire, we so humbly come before you in hopes that..."

Slightly Smarter Tarrasque: "I hunger." *eats faceman, daintily wipes lip*

Giving him 7 int just lets him eat you more efficiently.
Still a funny idea!

 

[saethone]

yeah i'd go for int drain as well if there was a way to do it

Cast flight on the party. Everyone stays out of range.

Open up the discussion with "Woah! No, don't eat us, wait a second. WAIT! Listen for a bit!" And pump up the charm.

Alternatively, sneak up on him at least 24 hours before he wakes up, and slip a Ring of Sustenance on his claw.

Then, when he's woken up, he's not hungry, so he has no reason to rampage eating everything out there.

I'm sure there's a demi-plane of cotton candy.

Plane shift is your only hope.

He might still rampage a little, just out of habit.
