(Btw i know quantum is a guy but is just my au so he's a girl in here)

I decided to remake my old art with news one

You can use Quantum to basically AFK grind in Arctic Apocalypse. Be sure to have Florence Sharkingale equipped and do not use Recycler Cannon.

Make a constantly looping tunnel of portals all connected to each other and somewhere in the portal loop's path, Toxic Barrels must be present. When you travel through the portal, you constantly loop around, killing everything nearby with Neon Sparks. You also heal from any damage taken thanks to Florence's ability activating once you touch the Toxic Barrels. You can do this throughout the whole Arctic Apocalypse run and basically make it a piece of cake.

Thanks to @Sboy13 for finding this out.
