Psi-Shadow

An inky blob of shadow stretches and twists, assuming a halfling-sized humanoid form.

Combat
Psi-shadows attack with a life-draining touch, though when changing shape they use the attacks normal to their new form. A psi-shadow remains in constant contact with the ground, trying especially to remain in the shadows.

Description
A psi-shadow is a 3-foot pool of inky black shadow that extends itself from the Black to the Prime Material plane. Strong light sources will destroy psi-shadows, but as long as there is a small enough light source to produce shadows, they can exist.

A psi-shadow only collects treasure when it needs to produce more shadows. The creature's treasure is usually found spread around the lair in small mounds, which it hopes lures greedy victims.

Once a psi-shadow is destroyed it vanishes, and all of its undead servant shadows become free-willed.

Psi-Shadow Society
Psi-shadows are guardians of twilight or any situation which produces enough light to create shadows but not enough light to destroy them. They become hostile towards anyone that threatens the shadows they guard, usually because their treasure is hidden in said shadows. Psi-shadows are strictly solitary and are very territorial towards their domains. Sometimes they may seek aid from other psi-shadows to protect their lair; in this case there may be up to 1d4 psi-shadows in one given area. A psi-shadow is expected to repay its kin with some of the treasure they helped guard.

Psi-shadows are sometimes seen with 1d6 undead shadow servants, and these shadow servants act as bodyguards and always attack aggressors and prevent them from harming the psi-shadow.

Some sages theorize that psi-shadows are the source of the creation of all undead shadows.
