This +1 striking frost katana is always cool to the touch, nearly uncomfortably so. Unadorned and with no tsuba, its honed blade is carved from a single tusk of dragon-turtle ivory and wrapped in strips of winter wolf hide. Strikes with the katana gain a +2 status bonus to damage rolls against creatures that have a status penalty to their Speed or are slowed. The status bonus increases to +3 if the weapon has a greater striking rune and +4 for major striking.

Traits
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.
ColdEffects with this trait deal cold damage. Creatures with this trait have a connection to magical cold.
DeadlyOn 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.
EvocationEffects and magic items with this trait are associated with the evocation school of magic, typically involving energy and elemental forces.
MagicalSomething with the magical trait is imbued with magical energies not tied to a specific tradition of magic. A magical item radiates a magic aura infused with its dominant school of magic. Some items or effects are closely tied to a particular tradition of magic. In these cases, the item has the arcane, divine, occult, or primal trait instead of the magical trait. Any of these traits indicate that the item is magical.
TwoHandThis weapon can be wielded with two hands. Doing so changes its weapon damage die to the indicated value. This change applies to all the weapon's damage dice, such as those from striking runes.
VersatileA versatile weapon can be used to deal a different type of damage than that listed in the Damage entry. This trait indicates the alternate damage type. For instance, a piercing weapon that is versatile S can be used to deal piercing or slashing damage. You choose the damage type each time you make an attack.
