Tarrasque

The legendary tarrasque is among the world's most destructive monsters. Thankfully, it spends most of its time in a deep torpor in an unknown cavern in a remote corner of the world—yet when it wakens, kingdoms die.

Although far from intelligent, the tarrasque is smart enough to understand a few words in Aklo (though it cannot speak). Likewise, it isn't mindless in its rampages, but instead focuses on targets that threaten it, and is difficult to distract with trickery.

Rush — Once per minute for 1 round, the tarrasque can move at a speed of 150 feet. This increases its Acrobatics bonus on checks made to jump to +87.

Spines — The tarrasque can loose a volley of six spear-like spines from its body as a standard action with a toss of its head or a lash of its tail. Make an attack roll for each spine—all targets must be within 30 feet of each other. The spines have a range increment of 120 ft.

Carapace — The tarrasque's scales deflect cones, lines, rays, and magic missile spells, rendering the tarrasque immune to such effects. There is a 30% chance a deflected effect reflects back in full force at the caster; otherwise it is simply negated.

Powerful Leaper — The tarrasque uses its Strength to modify Acrobatics checks made to jump, and has a +24 racial bonus on Acrobatics checks made to jump.
