Sirrushes speak Sylvan and Draconic.

A sirrush’s natural weapons are treated as epic for the purpose of overcoming damage reduction.
COMBAT

Stunning Roar (Ex): Every 1d4 rounds, a sirrush can loose a sonic attack of such volume that it stuns all creatures in a 60-foot spread for 1d4 rounds if they fail a fortitude saving throw (DC 47). The DC is Constitution-based.

Pounce (Ex): If a sirrush charges or leaps upon a foe during its first round of combat, it can make a full attack even if it has already taken a move action.

Headloss Resistance (Ex): A sirrush’s thick bony plate protects its neck like a shield and provides resistance from effects that could normally behead it, such as a vorpal weapon. When a sirrush or three-headed sir-rush would otherwise lose its head, it instead makes a fortitude saving throw (DC 10 + 1/2 HD of attacker + attacker’s Strength modifier). On a failed save, the sirrush’s head leaves its shoulders normally, but on a successful save, the sirrush is unaffected by the beheading. A sirrush dies when beheaded; a three-headed sirrush goes on fighting until all its heads are lost (the only penalty it incurs is one or two fewer bite attacks when it makes a full attack).

Covered in scales of copper and bronze, a sirrush has the shape of an unnaturally large deer or antelope, the forepaws of a lion and hindfeet like those of a huge bird of prey. Its head, reptilian and bearing a pair of coiled horns, rests atop a long and slender neck; its whiplike tail coils and uncoils along its haunches. Sirrush lair in desolate, abandoned temples and other such ruins.

A ferocious combatant, a sirrush attacks with claws and teeth; its claws inflict 1-6 hit points of damage, its bite 1-10 points. If truly enraged a sirrush will ignite in a nimbus of ruby-red flames, causing 2-8 hit points of damage upon contact with the fires and melting non-magical weapons that are used in combat against it. Sirrush are immune to damage from fire.
