Monster Manual III
Poison (Ex): Injury, Fortitude DC 18, initial and secondary damage 1d4 Dex. The save DC is Constitution-based. A creature reduced to 0 Dexterity in this manner becomes completely fossilized. Stone to flesh can restore a victim.
Shattering Shriek (Su): Once every 5 rounds, a stonesinger can emit an ear-piercing shriek as an attack. This shriek creates a blast of sonic energy that it can direct at any single target within 60 feet; the stonesinger makes a Perform (sing) check, using the target's touch AC as the check DC. If successful, the attack deals 12d6 points of nonlethal damage and the victim is stunned for 1d6 rounds (Fortitude DC 18 negates the stun). The save DC is Constitution-based.
Spell-like Abilities: 3/day - meld into stone, stone shape; 1/day - wall of stone (DC 19). Unlike normal spell-like abilities, these have a verbal component (the stonesinger must sing). Caster level 9th.
Skills: A stonesinger has a +8 racial bonus on Climb checks and can always choose to take 10 on a Climb check, even if rushed or threatened.
A stonesinger invariably sings during combat. While the sound may be unsettling to listeners, it does not otherwise affect the fight. Stonesingers are fond of making grandiose moves in combat, and they use Power Attack to make their attacks more impressive and painful when it is in their interest to do so.
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.
