Iron Chain

Iron Chains are the exclusive secondary weapons of Dark Knight, used in conjunction with Spears and Polearms. Most of these can be obtained via Job Advancement or purchased from the NPC Neville, while certain Iron Chains are obtained from the Evolving Secondary Weapon Selection Box, exchanging Princess No's Captivating Fragments, and various Events.

After completing the Genesis Weapon questline, players can upgrade eligible Iron Chains into an Astra Chain by completing the Astra Secondary Weapon questline. Astra Secondary Weapons can be upgraded in 3 stages and can have Star Force Enhancements applied (up to 15, 20, and 30 at each stage).
