This ritual attempts to shield the presence of your spirits from those who are able to detect them. Upon completion of the ritual, your spirits are enveloped in a protective aura that interferes with magic that detects undead and prevents those who are able to see into the Ethereal plane from perceiving them. Creatures that attempt to use these methods to detect your spirits must make a Wisdom saving throw against your spell save DC. On a failure, they are unable to perceive your spirits. On a success, their abilities or spells allow them to perceive your spirits.

This spell can only be cast as a ritual.
