Arrowhead of Giant Location

This raw carved obsidian Arrowhead, often worn as a necklace, has been imbued with Tribal Magics used by hunters to defend their tribes from the incursion of Giants.

The Arrowhead will silently vibrate when a Giant is within one mile, the vibrations growing in intensity, but are still not noticeable to anyone but the wearer, as the distance to the Giant lessens. 

If placed on a flat surface, or open palm, while vibrating it will shift to point towards the closest Giant.
