Cloak From Undead

By means of this spell, the caster or a single creature touched by the spellcaster is cloaked from undead in a similar manner to the 1st-level priest spell invisibility to undead. The protected creature can take any non-hostile action and any undead nearby will ignore him. If the cloaked individual attacks an undead creature, only the undead that is actually attacked notices the protected individual and can attack back. A cloaked priest or paladin cannot turn undead.

This spell is automatically effective against skeletons, zombies, ghouls, shadows, wights, ghasts, and other undead with 5 Hit Dice or fewer. Wraiths, mummies, spectres, and more powerful undead are allowed to make a saving throw vs. spell to see the cloaked individual. Vampires and undead creatures with 9 Hit Dice or more make this saving throw automatically. Extraplanar creatures and creatures that are not undead are not affected by this spell.

The material components of the spell are a piece of bone and a pinch of powdered silver.

Notes: Very rare spell. Known to be in the tome, Against the Undead.
