You can use your Dexterity modifier instead of your Strength modifier on attack rolls using this melee weapon. You still use your Strength modifier when calculating damage.

You can use this weapon to Grapple with the Athletics skill even if you don't have a free hand. This uses the weapon's reach (if different from your own) and adds the weapon's item bonus to attack rolls as an item bonus to the Athletics check. If you critically fail a check to Grapple using the weapon, you can drop the weapon to take the effects of a failure instead of a critical failure.

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 is being held by another creature).

You can throw this weapon as a ranged attack, and it is a ranged weapon when thrown. 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. Ranged weapons with this trait use the range increment specified in the weapon’s Range entry.

Something of uncommon rarity requires special training or comes from a particular culture or part of the world.

They typically can't be summoned. The DC of Recall Knowledge checks related to these creature is increased by 2.
