Cheats are enabled via the /cheater command. Press t to chat then run /cheater. The /cheater command requires the DLC to have been purchased first.
After they are enabled using /cheater press F1 to do god mode. God mode removes all current items on you, maxes out stats, gives 8 max hearts and 8 shields. God mode is a bit buggy on clients because your stats will be out of sync with the server.
0-7 to skip to levels. Level 6 is the victory screen. Level 0 is the lobby. Level 7 is the "Intrigue of Werewolf" gamemode map.
