One of the ways you can upgrade your armors in Eiyuden Chronicle: Rising is via the Armor Shop, which works a bit differently than the Smithy. While the Smithy will just increase the level of your armor and its stats, the Armor Shop will actually increase the rank of it. While this might add a minute stat increase, it does actually improve the abilities of the Armor, giving you new techniques. For example, CJ only has her basic dash on the ground at the beginning of the game, but as you upgrade her armor at the shop, she will gain the ability to do this in the air. Thus, it’s very important to not only level up your armors at the Smithy for more defense, but also the Armor Shop to get those extra abilities.
