What do you show the king so he doesnt attack? All its says for me is 'show nothing'
Aah... You are in the dungeon, aren't you? Well the dungeon has a specific path that you must follow. If you have downloaded that google drive guide then you will know how to get through the dungeon. If you follow that you will get a prince, a jester and a knight emblem/badge. Show the guard the jester one to proceed and show the king the prince one.
NOTE- if you show the king the knight one you will have to fight him and you MUST avoid that battle by showing him the prince one.
