Isphinn

Tremorsense allows a monster to feel the vibrations through a solid surface caused by movement. It is an imprecise sense with a limited range (listed in the ability). Tremorsense functions only if the monster is on the same surface as the subject, and only if the subject is moving along (or burrowing through) the surface.

A constant spell affects the monster without the monster needing to cast it, and its duration is unlimited. If a constant spell gets counteracted, the monster can reactivate it by spending the normal spellcasting actions the spell requires.

The shaitan can Burrow through dirt and stone at its full burrow Speed, leaving no tunnels or signs of its passing.

When the shaitan Pushes a creature into a stone barrier, the target must succeed at a DC 22 reflex save or become merged with the barrier (as One with Stone). The victim can attempt to Escape.

Requirements The monster's last action was a successful Strike that lists Push in its damage entry Effect The monster attempts to Shove the creature. This attempt neither applies nor counts toward the monster's multiple attack penalty. If Push lists a distance, change the distance the creature is pushed on a success to that distance.
