Crystal Xorn

CREATURE 7

These squat, rotund elementals have three legs, three arms, three eyes, and one massive maw, which they fill with the gems and metals they find so delicious.


Earth elementals make excellent bodyguards for adventuresome spelunkers and are ideal protectors of important subterranean locations such as vaults and treasuries.

Tremorsense (Imprecise) 60 feet

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.

Melee Jaw +18 (deadly d10), Damage 2d10+8 piercing plus Crystal Corruption
Melee Claw +18 (agile, unarmed), Damage 2d6+8 slashing plus Crystal Corruption
Claw Frenzy

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.

Crystal Corruption (arcane, curse, incapacitation)

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.

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.
Earth Glide

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.
