Ground trace

Ground trace was a divination spell that allowed the caster to trace the pathway of certain objects or passageways that descended beneath the ground.

Effects
In order to be cast, the caster selected a feature that, while was visible from ground level, continued beneath the earth. The object targeted by the spell could be nearly anything from a tree and its root system, a keep with a dungeon, a system of underground water pipes, etc. Ground trace allowed the caster to discern the pathway of the subterranean passageway in their mind without descending underground.

The amount of knowledge the caster gained about a pathway was limited to how far they could travel its path above ground, before the end of the spell's duration.

History
The specifications of this spell were inscribed within the Mielikkian relic, Yornar's Trail Companion.

Components
In addition to verbal and somatic components, this spell required a single hair taken from the caster and a piece of string.
