Traits
This rarity indicates that a rules element is very difficult to find in the game world. A rare feat, spell, item or the like is available to players only if the GM decides to include it in the game, typically through discovery during play. Creatures with this trait are rare. They typically can't be summoned. The DC of Recall Knowledge checks related to these creatures is increased by 5.
AgileThe multiple attack penalty you take with this weapon on the second attack on your turn is -4 instead of -5, and -8 instead of -10 on the third and subsequent attacks in the turn.
EvocationEffects and magic items with this trait are associated with the evocation school of magic, typically involving energy and elemental forces.
FinesseYou can use your Dexterity modifier instead of your Strength modifier on attack rolls using this melee weapon. You still use your Strength modifier when calculating damage.
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.
NecromancyEffects and magic items with this trait are associated with the necromancy school of magic, typically involving forces of life and death.
ThrownYou can throw this weapon as a ranged attack. A thrown weapon adds your Strength modifier to damage just like a melee weapon does. When this trait appears on a melee weapon, it also includes the range increment.
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.
