Snare

When hit by this wrist launcher ammunition, a Medium or smaller creature is restrained until it is freed. A snare has no effect on formless or Large or larger creatures. A creature can use its action to make a DC 13 Strength or Dexterity check (the target chooses the ability to use), freeing itself or another creature within its reach on a success. The snare has an AC of 10, 5 hit points, and immunity to all damage not dealt by melee weapons. Destroying the snare frees the creature without harming it and immediately ends the snare's effects.
