Monk
Abilities with this trait are from the [monk](/Classes.aspx?ID=8) class. A weapon with this trait is primarily used by monks.
Trip
You can use this weapon to Trip 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 Trip using the weapon, you can drop the weapon to take the effects of a failure instead of a critical failure.

This heavy blade is favored by guardians of religious sites. It has a distinctive, crescent-shaped blade that seems to be a mix of a sickle and sword. It often has holes drilled into the blade or the pommel so that bells or other holy trinkets can be affixed to the weapon as an aid for prayer or mediation.
Certain feats, class features, weapon runes, and other effects can grant you additional benefits when you make a Strike with certain weapons and get a critical success. This is called a critical specialization effect. The exact effect depends on which weapon group your weapon belongs to, as listed below. You can always decide not to add the critical specialization effect of your weapon.
