Earthdawn - Who Really Kaers?
The adept, who must possess an item directly associated with the target, such as a strand of hair, a bit of masonry, or even a Pattern Item, determines the location of a character or object relative to his position by firing a missle into the air and making a Direction Arrow Test against the target’s Spell Defense. Regardless of the outcome, the missle rises to its full height, then plummets to the earth where it shatters into sparks. If successful, the sparks form a 1-yard-long flaming arrow pointing in the direction of the target. If the test fails, or the target is further than Direction Arrow Rank miles away from the adept, the burning fragments scatter haphazardly, with no clear direction indicated.
