Something of uncommon rarity requires special training or comes from a particular culture or part of the world. Some character choices give access to uncommon options, and the GM can choose to allow access for anyone. Less is known about uncommon creatures than common creatures. They typically can't be summoned. The DC of Recall Knowledge checks related to these creature is increased by 2.

Clockworks are intricate, complex constructs that can be programmed to perform specific functions.

On a critical hit, the weapon adds a weapon damage die of the listed size. Roll this after doubling the weapon's damage. This increases to two dice if the weapon has a greater striking rune and three dice if the weapon has a major striking rune. For instance, a rapier with a greater striking rune deals 2d8 extra piercing damage on a critical hit. An ability that changes the size of the weapon's normal damage dice doesn't change the size of its deadly die.

Abilities with this trait are from the monk class. A weapon with this trait is primarily used by monks.

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.

You can use this weapon to Shove 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 Shove using the weapon, you can drop the weapon to take the effects of a failure instead of a critical failure.
