A sharnbulette can perform a special kind of pounce attack by jumping into combat. When a sharnbulette charges, it can make a DC 20 Acrobatics check to jump into the air and land next to its enemies. If it makes the Acrobatics check, it can follow up with four claw attacks against foes in reach, but cannot make a bite attack.
Savage Bite (Ex)
A sharnbulette’s bite is particularly dangerous. It applies 1-1/2 times its Strength modifier to damage inflicted with its bite attack, and threatens a critical hit on a 19–20.
A sharnbulette has large spines that jut from between its armor plates; any creature attacking it with natural attacks or unarmed strikes take 1d6 damage and must make a DC 16 Reflex save or have the quill break off and embed in its flesh. Lodged quills impose a –1 penalty on attacks, saves, and skill checks per quill. The save DC is Dexterity-based.
