Bonus stages are stages that come after legend. They have 3 episodes, which do not follow the canonical storyline.
Bonus 1-1 does not require any key. Every other bonus stage requires the appropriate key. Depending on the stage, the required key is obtainable either from the key trader, daily key quest, or the previous stage.
Each episode of bonus has two equipment sets to obtain. Completing both full sets in an episode will award +1 SP.
