Locate

If a Sextant is missing, this spell can substitute.

Casting it, it reveals the exact location of the mage on Britannia in longitude and latitude, the same as a Sextant would do. However, this spell nonetheless is a poor substitute for a Sextant, since Nightshade is rare and expensive and should be used for more useful spells. Over time it becomes so expensive, that simply buying the instrument saves much money in the long run.
