First I would recommend a controller for doing this.

You're gonna want to change the inputs of two buttons of your choice (personally I have L2 and R2 bound) to rapidly press heavy and quick attack as well as the space key or the 4 face buttons of the controller.

Make sure you enable turbo on everything

Then all you have to do is use the character that recovers stamina from rapid space key presses and voila, you are now officially invincible.


As long as there are enough enemies around you will be fine but there's a chance you might lose one or two hearts in the earlier rounds as your stamina will not recover as quickly, just be careful until you reach a round that has groups of enemies running at you then you can turn your brain off.

Enjoy picking up a myriad of treasure boxes.
