A sharklike creature soars through the air, diving down towards its prey. It looks like a hammerhead with long wings instead of fins and a tail that tapers down to a whiplike point.

The dimensional predator is a common menace to planar travelers. Like the mundane sharks it resembles, it swims through the cosmos in search of its next meal. These beasts flash into existence, swoop down on their targets, and then slip back into the ethereal in a matter of moments. Sometimes, a party of explorers loses a member to these creatures without realizing his fate.

Combat

Dimensional predators prefer to attack weak, injured parties rather than fresh, well-rested ones. Like sharks, once they catch scent of fresh blood they are relentless hunters. They prefer to use their plane lurker ability in combination with Flyby Attack, materializing, swooping in to attack, and then slipping back into the ether to prepare for another strike.

Tail Sting (Ex): The dimensional predator’s tail is cloaked in a faint nimbus of elemental energy. It makes touch attacks when fighting with its tail, and in addition to the physical damage victims must make a Fortitude save (DC 15) or be stunned for 1d3 rounds.

Planar Lurker (Su): The predator can slip between the fabric of the planes, allowing it to fade out of existence while casting its senses into its immediate area. Treat this as the spell ethereal jaunt as cast by a 12th-level sorcerer. The predator can move into and out of the ethereal as a move-equivalent action.
