Stalk

This spell makes the target nearly invisible in natural surroundings and almost totally silent as if he or she were wearing cloak and boots of elvenkind. Furthermore, the recipient’s scent is almost completely masked. The dweomer makes a stationary recipient undetectable by non-magical means at any range over 30 feet. Movement doesn’t negate the spell; it only makes non-magical detection possible (the subject of the stalk spell still can move silently with base 50% success).

The spell ends when its duration expires or whenever the recipient attacks.
