Crystal Xorn

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.

This monster can see in all directions simultaneously and therefore can't be flanked.

The xorn makes three claw Strikes; no more than two can be against the same target. These attacks count toward the xorn's multiple attack penalty, but the penalty doesn't increase until after all the attacks have been made.

This affliction's sickened, slowed, and paralyzed conditions can't be removed until this affliction is removed. A creature affected by crystal corruption slowly turns into crystal until it is petrified. Creatures with both the earth and elemental traits instead become carriers and suffer no ill effects aside from gaining the vulnerability to sonic. Saving Throw DC 22 fortitude Stage 1 Sickened 1 (1 hour) Stage 2 vulnerable 5 sonic and sickened 1 (1 day) Stage 3 vulnerable 5 sonic and Slowed 1 (1 day) Stage 4 vulnerable 10 sonic and Paralyzed (1 day) Stage 5 vulnerable 10 sonic and the creature is permanently Petrified.

The xorn can Burrow through any earthen matter, including rock. When it does so, the xorn moves at its full burrow Speed, leaving no tunnels or signs of its passing.
