Woven Bands of Camaraderie are a set of matching bracelets made of a woven material (normally sturdy twine but any fiber will do) and bearing a few beads or charms, at least one of which matches across the set. While wearing one of these bracelets, you can use an action to cast the sending spell from it. The target is any other creature wearing a bracelet from the same set. If no creature is wearing the intended bracelet, you know that fact as soon as you use the band and don't cast the spell.

You can also use a reaction to cast the shield spell from the bracelet. You may cast the spell normally or target another creature you can see wearing a matched bracelet, provided they qualify for the spell's trigger.

Once either sending or shield is cast through the stones, that spell can't be used again until the next dawn. If any of the bands in a set is destroyed, the other bands continue to function until one remains, which becomes nonmagical.
