Weapon (any with the thrown property), uncommon (requires attunement)
You have a +1 bonus to attack and damage rolls made with this magic weapon. When you make an attack roll that isn’t a critical failure, you can use 10 feet of movement for it to return to your hand.
Pretty specific. Last weekend we were play testing my upcoming module, The Lost Watchmen of Rotstone Light, and BriW was playing a double hand axe, two-weapon fighting Eldritch Knight. We were in search of an uncommon item that allowed her to just carry her two bound axes and have the binding be useful for sometimes making three throws a round with her extra attack. This allowed her to attack three times every other turn (except when she rolled ones). So, it did what we needed it to do. Your mileage may vary.
