With an aerodynamic cutting edge and a curved handle, this +3 major striking battle axe is perfectly suited to whirling motions, and in fact seems like it wants to whirl free from your grip. A Strike with this axe that benefits from the sweep trait's circumstance bonus on attack rolls also gains a +4 circumstance bonus to the damage roll.

Traits
Anything that doesn't list another rarity trait (uncommon, rare, or unique) automatically has the common trait. This rarity indicates that an ability, item, or spell is available to all players who meet the prerequisites for it. A creature of this rarity is generally known and can be summoned with the appropriate summon spell.
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.
SweepThis weapon makes wide sweeping or spinning attacks, making it easier to attack multiple enemies. When you attack with this weapon, you gain a +1 circumstance bonus to your attack roll if you already attempted to attack a different target this turn using this weapon.
