Resin Harpoon Arrow

Maybe a use for resin would be a sticky resin arrow, that can be only used with a crossbow. it takes double the time to load and when launched it fires a harpoon hook attached to your crossbow, you can use it as a grappling hook but if you hook an entity, it would be a more powerful leash pulling the entity towards you. you can let go of the tether with right click.
