Item: Frost Fair Yanyuedao

Artifact: Items with this trait are artifacts. These magic items can't be crafted by normal means, and they can't be damaged by normal means. Artifacts are always rare or unique.

Cold: Effects with this trait deal cold damage. Creatures with this trait have a connection to magical cold.

Deadly: 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.

Forceful: This weapon becomes more dangerous as you build momentum. When you attack with it more than once on your turn, the second attack gains a circumstance bonus to damage equal to the number of weapon damage dice, and each later attack gains a circumstance bonus to damage equal to double the number of damage dice.

Reach: This weapon can be used to attack enemies up to 10 feet away instead of only adjacent enemies. For creatures with reach, the weapon increases their reach by 5 feet.
