Shadow Dance

This spell transforms the caster or a touched recipient creature and all worn or carried material into a translucent, insubstantial state, resembling the creature known as a shadow. Like a shadow, this form is 90% undetectable in all but the brightest sunlight, except to an observer who knows of its presence and watches it continuously. While affected by the spell, the recipient's movements are silent, and he can pass through any crack or opening. Though an intangible creature cannot cast spells requiring material components or launch physical attacks, the state can be ended instantly by the recipient's silent act of will.

The user of a shadow dance is protected at all times by an effect identical to a feather fall spell, and is immune to all undead or magical energy draining attacks. This immunity includes the strength drain of shadows, lifeforce attacks (such as the chill touch of a lich or a wizard employing the spell of the same name), and the level draining of more powerful undead.

Shadow dance users cannot fly, but can dive downward, trusting to the feather fall property of the spell for protection. They can also climb empty air in a rhythmic manner that resembles some dances. This upward movement is equal to a levitation spell (an upward movement rate of 2, no horizontal movement, weight limit of 100 lbs. per level of experience of the caster).

The material component of this spell is a cobweb or eyelash that has been touched at some time by moonlight.
