basically, one of us would go onto their stacked, normal non-hardmode save file, and beat cruel king with the other on their hardmode save

we did it two times (he was on his normal, stacked save file and i was on my hardmode save. then he was on his hardmode save, and i was on my normal save (also fluffy equipped the hardmode card (which i DIDNT want him to do, but thought he had it unequipped anyways, so it took us like 5 tries to beat cruel king (i on the other hand, DIDNT equip the hardmode card and beat it first try with him)))

and we both got the heartless and bloxxer badges (yes, we both did not save jim)

planning to do that with all the bosses lmao
