The wavering silhouette of a humanoid materializes. Its reaching, half-seen hand threatens to snag your soul.

A murk is an incorporeal, free-roaming blot of undead essence with a nugget of sentience. It exists to spread gloom and, when possible, drain life energy.

Most murks are no more than 6 feet tall. They cannot speak intelligibly.

Combat

Murks haunt tombs, crypts, cemeteries, and other places where undead roam.

Confer Negative Level (Su): Any humanoid reduced to Wisdom 0 by a murk (see Wisdom damage, below) gains one negative level. The DC is 12 for the Fortitude save to remove a negative level. The save DC is Charisma-based. When a murk bestows a negative level on a victim, it gains 5 temporary hit points (10 on a critical hit). These temporary hit points last for up to 1 hour.

A murk that bestows a negative level on a 1 HD creature kills the creature, which becomes a murk under the control of its killer within 1d4 rounds.

Inescapable Craving: A murk has an inescapable craving (see Undead Metabolism) for Wisdom and life force, which it satisfies by using its Wisdom damage and confer negative level abilities.

Wisdom Damage (Su): The touch of a murk deals 1d6 points of Wisdom damage to a living foe.
