You reach out and peel the subject's shadow away, then wrap it inside your own.

The target of this horrid mystery must succeed on a Will saving throw or die. If the creature succumbs to the mystery and dies, it immediately returns to life, gains the dark creature template, and is under your control. The creature remains in this state for 1 round per level, and then dies again.

Your foes suddenly find their bodies infused with shadowstuff, weakening them greatly.

This mystery functions like the mystery flesh fails, except that you can affect multiple subjects, and you deal either 6 points of Strength damage, 6 points of Dexterity damage, or 4 points of Constitution damage. You must deal the same kind of ability damage to all subjects.

Draining shadows erupt around your foes, funneling their essence and energy into the Plane of Shadow.

Your touch deals 1d6 points of nonlethal damage per caster level (maximum 20d6) and causes the subject to become exhausted for 1 round per caster level. A Fortitude save reduces the damage by half and decreases the exhaustion to fatigue. This mystery does not stack with itself, so a creature fatigued by saving against one casting does not become exhausted by saving against a second casting.

Tendrils of darkness flow from the ground like smoke, filling the area with writhing, shifting darkness. A cold draft washes over your soul even as the tendrils rise.

The area of deadly shade is filled with shadowy illumination, as per darkness. In addition, each time you invoke this mystery, decide if you wish the spell to deal or absorb damage.

An oily black smoke rolls out of nowhere, obscuring sight and sound. It leaves a distasteful residue on everything within, and the scent is one of open sewers and putrefied flesh.

Plumes of blackness swiftly fill the air like a viscous fog. The shifting of shadow and mists just barely suggests the presence of screaming faces and indescribable horrors lurking in the dark.

Darkness surrounds your hand, turning it into a deadly weapon.

Umbral touch infuses one of your hands with dark, shadowy energy, allowing you to make debilitating melee touch attacks. A successful strike deals 5d6 points of damage to a target, which must succeed on a Fortitude saving throw or also be slowed. While this mystery is active, you threaten an area as if you were armed and can make attacks of opportunity with your umbral touch.

You open your enemy to the darkness, trading his physical attributes for weaker belonging to creatures of shadow.

You deal either 4 points of Strength damage, 4 points of Dexterity damage, or 2 points of Constitution damage to the subject; you choose which kind of ability damage when you cast the mystery.

A wave of darkness washes over the subject, sapping his energy into the Plane of Shadow.

Your touch deals 1d6 points of nonlethal damage per caster level (maximum 5d6) and causes the subject to become fatigued for 1 round per caster level. This mystery does not stack with itself, so a creature fatigued by one casting does not become exhausted by a second casting.

By speaking via a conduit on through the Plane of Shadow, you deliver a commanding message.

This mystery functions like the spell command.
A second function is a necromancy effect. Undead and constructs that fail their saving throw against this effect are dazed for 1 round.
You can only use one version of this mystery in a single casting.
