Forgotten Realms Campaign Setting
Paralyzing Ray (Su): A rock wyrm's third eye can emit a paralyzing ray once every 1d4 rounds. The ray has a range of 75 feet. The rock wyrm must succeed at a ranged touch attack (+10 attack bonus) against its target. Targets struck by the ray must make a Fortitude save (DC 17) or be paralyzed for 1d6+2 minutes.
Pounce (Ex): If a rock wyrm leaps upon a foe during the first round of combat it can make a full attack even if it has already taken a move action.
Fast Healing (Ex): A rock wyrm heals 1 point of damage each round so long as it has at least 1 hit point.
Mimicry (Ex): Rock wyrms can mimic most speaking voices perfectly, plus other vocal sounds ranging from coughing and retching to high bird-trills or deep, thunderous croakings. They can remember and perfectly reproduce phrases they have overheard, and they have a knack for echoing vocal mannerisms and catchphrases.
Skills: Rock wyrms can change the reflectiveness, color, and apparent texture of their hides, allowing them to blend into their surroundings like chameleons. They gain a +4 racial bonus on Hide checks. *In rocky areas, this bonus on Hide checks improves to +8.
*A rock wyrm's mimicry ability confers a +4 racial bonus on Bluff checks involving attempts to deceive foes by mimicking a particular voice or animal call.
