Bonus Round is the sixth and final episode for the Inventor.

In the Bonus Round episodes, you get to choose your initial equipment. Also, the item drops for the most part are combined so you can get most of the equipment available in both normal and Parallel Universe episodes.

Once you go down a floor, two new rules are chosen for you: one visible for you to choose and one other rule whose identity is hidden from you until you choose it. You choose one of the rules to implement for the rest of the episode. Some can be beneficial to you, but many of them benefit your enemies.

After you complete this episode, you get a third choice of initial equipment, but all enemy equipment will be upgraded during the round. Completing this hard mode will complete a challenge and grant an extra enemy bio to read.

The Inventor's Limit Break is Focus, which cause all dice to become 6, and her starting gadget is Replicate, which copies a random dice.

All items list the available equipment and the gadget that it becomes after each fight.
