I see. The price of Meloetta dungeon for your case is 1.5m. The Pinkan Dungeon has it own requirement to be unlocked first, please refer to the guide within the section "Pinkan Dungeon detail" in the first page for more detail.
Hi, thank you for reaching out, may I know your in-game name and server for a correct quotation please? Or you can contact my ingame Mingrenpro in Gold server, or hasekirie in discord dm in case I'm not online ingame or on the forum.
