Open the Kit Editor with /duel kit or /fightclub kit, or tap the Kit Editor button in the kit picker. Choose a kit and drag its items into the slots and offhand you want. The kit's item set is fixed for balance, so you only rearrange positions and never add or remove gear. Save & Go Back stores your layout, Reset to Default restores the original order, and Cancel discards your changes. Your saved layout follows you across servers and is applied automatically at the start of every duel with that kit.
