After you hit with the weapon, you can use an Interact action to give the target a –10-foot circumstance penalty to all Speeds. The penalty ends after the target takes a move action, at the start of your next turn, if you attack with the weapon, or if you move out of reach of the target, whichever comes first.

Natural attacks with this trait can be used to attack creatures up to the listed distance away instead of only adjacent creatures. Weapons with this trait are long and can be used to attack creatures up to 10 feet away instead of only adjacent creatures. For creatures that already have reach with the limb or limbs that wield the weapon, the weapon increases their reach by 5 feet.

This weapon is attached to a length of rope or chain that allows you to retrieve it after it has left your hand. If you have a free hand (including if you've just thrown a two-handed tethered weapon and have a hand holding nothing but the weapon's tether), you can use an Interact action to pull the weapon back into your grasp after you have thrown it as a ranged attack or after it has been disarmed (unless it's being held by another creature).

You can throw this weapon as a ranged attack. A thrown weapon adds your Strength modifier to damage just like a melee weapon does. When this trait appears on a melee weapon, it also includes the range increment.
