The Smithy is a shop in Hyrule Warriors. It can be found in the Bazaar like other shops in the game. It offers several services for modifying weapons at the cost of some Rupees.
Weapon skills are divided into categories based on their effects. Skills in some categories require a certain number of kills with that particular weapon to unlock. There is a limit to how many skills a weapon can have within each category, and a weapon may not have more than one of the same skill.

Legendary (LEG) Skills
A weapon may have a maximum of 1 LEG Skill. Evil's Bane is only available on the Master Sword, which cannot receive Legendary. In order to unlock Evil's Bane, one must unlock every weapon in the game (all three ranks), excluding those from DLC packs and amiibo. Then, the 25,000 KO counter will decrement as with other KO-locked skills. In order to unlock Legendary, one must first unlock Evil's Bane, then KO 25,000 enemies. Enemies defeated before unlocking all the weapons or Evil's Bane will not be counted.
|Evil's Bane||N/A||Increases base weapon strength by 200.|
|Legendary||50,000||Increases base weapon strength to 300.|
Evil's Bane increases the strength of the Master Sword from 300 to 500. Legendary increases the base strength (before stars) to 300. Stars are then calculated based on this new value. For example, a three-star R2 weapon normally has a strength of 195 (150 base + 30% of 150 (45) from stars). With the Legendary skill, its strength becomes 390 (300 base + 30% of 300 (90) from stars). Therefore, Legendary will have the same effect on any rank weapons with the same number of stars.
