The Tarrasque does just massive damage and has tons of HP. Unless you have dual immunity, it will destroy so much stuff in your pack that killing it will leave you significantly worse off. When breath attenuation was too forgiving, I sometimes killed it as a High Elf mage with nether bolt. Make long tunnels with stone to mud and digging, then plink it from far away, when it gets close teleport and repeat. But that was because
* it was doing much less damage
* High elf mage is desperate for EXP.
