This spell bestows an unerring "homing" sense on a person so that the individual knows how to take a vessel that she or he is steering or navigating back to its home port, regardless of how far off-course the ship may have been blown by storm or happenstance. The home port is defined as where the ship was launched or the place it returns to berth most often. This spell cannot be modified to home in on an intervening port of call.
The material component is a pebble from the vessel's native port, which must be held by the spell recipient. The rock is not consumed in the spellcasting.
Notes: Granted by Valkur, Captain of the Waves, of the Forgotten Realms setting.
