Have crossed out the following information above due to a change in 1 of the previous patches Stage 2 - Heart Strings can now be completed with 5 players by using newly added cloud megaphone NPCs in the map. Stage 5 - Fluttering Hearts now requires all party members to reach the end. Stage 7 - Amos' Vault now spawns players on separate spawn points. https://royals.ms/forum/threads/update-87-26-10-23.224727/
