Traits
You can use the momentum from a missed attack with this weapon to lead into your next attack. After missing with this weapon on your turn, you gain a +1 circumstance bonus to your next attack with this weapon before the end of your turn.
You can use this weapon to Disarm 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 (if any) as an item bonus to the Athletics check. If you critically fail a check to Disarm using the weapon, you can drop the weapon to take the effects of a failure instead of a critical failure. On a critical success, you still need a free hand if you want to take the item.
Abilities with this trait are from the monk class. A weapon with this trait is primarily used by monks.
This weapon can be used defensively to block attacks. While wielding this weapon, if your proficiency with it is trained or better, you can spend a single action to position your weapon defensively, gaining a +1 circumstance bonus to AC until the start of your next turn.
