Armsbreaking is the process of reverting a two-handed weapon that has been fused through Armsfusion to a single weapon. Talk to either <Artur> in Pandaemonium or <Curio> in Sanctum. Only unequipped weapons can be reverted. Place the weapon into the top slot. The result of the process will then be displayed. There is no fee for armsbreaking. Once separated, the primary weapon will retain any enchantments, godstone and manastones present prior to armsbreaking.
