Anchor Stone

This pair of lead stones is in two parts. The "Chain" and the "Anchor". The Chain is a simple ranged weapon (60/120). On a hit, the anchor reduces the target's movement speed is reduced by 10. Once attached. For every 30 feet away the chained creature is from the anchor, it's movement speed is reduced by another 10 feet. The chained creature can use its action to make a strength (athletics) check DC 15 to remove the anchor.  The creature holding the anchor's speed is also reduced by 10 for every 30 feet the target is away from it. In addition, the anchoring creature always knows the location and distance they are from the chained creature. The Anchor and chain maintain this  property for 1 hour at which point both turn to dust.
