This cantrip causes a glowing arrow to appear in the cupped palm of the wizard. It is a light green in colour, and wavers around in the general direction of north. The spell will work underground, as well as at sea, and is not affected by a lodestone, but it is only exactly right about 25% of the time and may sometimes be completely off (10% chance). The material component is a sliver of iron.
