Blindness (Ex)

A zhen worm perceives solely through its tremorsense ability. It is immune to all sight-based effects and attacks, including gaze attacks.

Dissolve Flesh (Ex)

Though too dilute to cause damage in combat, a zhen worm's acidic mucus reduces a Medium-sized corpse to bones and a pool of foul-smelling slurry in 1d4 days. Each size category above Medium doubles the amount of time required, and each size category smaller than Medium halves it.

Protective Mucus (Ex)

Weapons slip off the slick slime that coats a zhen worm, and fire has difficulty burning it away.

Zhen worms take half damage from weapons and fire. This ability does not reduce damage from confirmed critical hits.

Zhen Distillate

Through alchemical processes, zhen worm mucus can be distilled into a preservative ointment. When spread liberally over a dead game animal, zhen distillate preserves the meat for 1 month. If left on for at least 3 days, the distillate dissolves away hair, nails, and skin, while leaving muscles and organs untouched. If not thoroughly washed away with wine or a similar alcoholic liquid, zhen distillate leaves behind a foul aftertaste. A flask of zhen distillate weighs 1 pound, costs 50 gp, and preserves the corpse of a Large creature. Each step up or down from Large doubles or halves, respectively, the amount of distillate needed.

The mucus harvested from a single zhen worm can be processed into one flask of distillate with a successful DC 25 Craft (alchemy) check.
