Odyle Energy Cube loot

Defeat the bosses, then open the Odyle Energy Cube once per clear: one claim pays out the pool of every boss you defeated, for the cost below. Each row rolls on its own at its listed chance (above 100% means several sure drops); a package gives one random item from its pool. Claims also fill the Guaranteed Reward, which lets you choose one item each time it is full.
