Weapon Fusion

Weapon Fusion is a feature of the Warriors Orochi series that allows players to personalize a character's weapon with attributes using Growth Points earned from completing stages. Each weapon can only hold up to eight attributes at a time. Similar to the elemental system used in Dynasty Warriors and Samurai Warriors, these abilities are activated by performing charge attacks against opponents.

Weapon Attributes
Weapon Attributes require growth points in order to be attached to a particular weapon. Said points can also be used to create empty slots or increase base attack power.

Upgrade Skills
Upgrade Skills are additional attributes made by fusing certain attributes and materials together. Up to three can be attached to a single weapon.

Normal Abilities
Normal Abilities can be stacked up to +10 to increase their effect.

Gold Abilities
Gold Abilities are rare and hard to find, but they do give weapons powerful skills which cannot be stacked.
