For the "item" badge, I beat the 3rd "pink jewel" named "the good, the bad and the fiery" until I got the star yet I didn't get the badge. Is it bugged?
yes, I found a bug, for the last championship, I bought the "Fangs of Werewolf", the "Oak of Zeus", the "Shoe of Hermes" and the "Stardust", I used them all and did 250k dmg, idk if there is a single item that can do it but with these four, i did that dmg twice
