Weapon Fusion

Weapon Fusion (武器融合, Buki Yūgō) is a feature introduced in the Warriors Orochi series. It enables players to personalize any weapons they have with various attributes using growth points accumulated by clearing stages. Each weapon can hold up to eight attributes that activate when performing a charge attack similar to the elemental system utilized in both the Dynasty Warriors and Samurai Warriors series.

Elements from both IPs are included alongside new ones exclusive to Warriors Orochi titles. They also become more potent the higher their value count becomes. It should be noted that some attributes do not mesh well with one another, so players need to pair up those that complement each other to great effect.

Weapon Attributes
When attempting to imbue weapons with new attributes (with +10 being the limit cap for each one), growth points are needed to attach them. These points are also used for creating empty slots or increasing a weapon's base attack power (up to +20 per weapon).

Upgrade Skills
Introduced in Warriors Orochi 2, these additional attributes are made by fusing different attributes and materials together. Up to three upgrade skills can be attached to a single weapon.

In Warriors Orochi 3, attaching attributes to a weapon requires a copious amount of gems. The cost itself depends on the attribute's current level as well as its rarity. For instance, a single attribute stock has a fixed cost of 100 gems plus another amount based on its current level within the target weapon multiplied by 100. For gold attributes, they all cost 2,000 gems to attach.

Gold attributes are hard to come by, yet they provide benefits that outstrip those of their more mundane counterparts. The Ultimate expansion adds new attributes to the mix, some of which are compound versions of two existing ones. It also enables players to obtain or craft orbs containing them.

Orb Information
While the fourth entry limits each weapon with up to 8 attributes, Ultimate allows players to attach two more by unlocking new features in the base camp. Attributes can also be bought with gems upon clearing the first battle of chapter 4, though gold-colored ones are only found in weapons gained from Pandemonium battles.
