Combat

A tralusk invariably begins singing during combat. While this is unsettling to most listeners, it does not otherwise affect the fight. Tralusks are fond of grandiose moves in combat and almost always uses the Power Attack feat to make their attacks more impressive and painful.

Poison (Su): A tralusk's claws drip a thick fluid that resembles mud. This fluid is in fact a potent poison. Any creature struck by a tralusk's claw must make a Fortitude saving throw (DC 18) or take 1 point of permanent Dexterity drain as their body slowly begins to stiffen. Anyone drained to 0 Dexterity in this manner becomes completely fossilized. A stone to flesh spell can restore the victim.

Shattering Shriek (Su): Once every 5 rounds, a tralusk can emit an ear-piercing shriek as an attack. This shriek creates a beam of sonic energy that the creature can direct at any single target within 60 feet; the tralusk must hit with a ranged touch attack, substituting a perform check for the attack roll. If successful, the victim suffers 12d6 points of subdual damage and must make a Fortitude saving throw (DC 18) or be stunned for 1d6 rounds.

Alternatively, the tralusk can attempt to shatter an object with this shriek. It automatically hits, but it must make a Perform check (DC equals the object's Break DC as listed on in Object HP table).

Earth Subtype

This subtype usually is used for elementals and outsiders with a connection to the Elemental Plane of Earth. Earth creatures usually have burrow speeds, and most earth creatures can burrow through solid rock.
