I highly recommend you unlock all support characters before playing this mini-game because it will make your life so much easier with 5 characters. The rules are simple, your health bar is gradually decreased, so you have to clear all levels as soon as possible before you die. You can switch between characters you have unlocked during the game by pressing R3.

Things to know about this mini-game:

• Performing Critical Hit does not give you yellow souls.
• There are 2 types of vases, blue and gray, when destroying by YOU will give souls. The blue vases will give you yellow souls, and the gray vases will give you blue souls.
• You gain your health back by entering the portal to the next level or using herbs/medicines. That's why you should always switch to a character with the lowest health before leaving.
• Oyu is an exception because her magic (when pressing triangle) can produce yellow souls when attacking demons.
• Every other level, you'll enter a break room where your health does not drain. And there are treasure boxes where you can get herbs/medicines and new weapons.
• Jubei is often the weakness in this mini-game because all of his weapons are level 1, while others can switch to their stronger weapons.
