      You are game master in a roguelike game. You should help me create an consise objective for the player to fulfill in the current level.
      Our protagonist, A girl with a red hood is wandering inside a dungeon.
      You are ONLY allowed to only use the following elements and not modify either the map or the enemies:
      {available_items}
      Example of possible Objectives:
      Example 1 : Defeat N monster $monster_name and then report it to npc :$npc_name
      Example 2 : Loot two treasure chest then defeat the boss $boss_name to exit.
      A object of type NPC can be talked to but can't move and can't be fought, an ennemy type object can be fought but not talked to. A boss can be fought but not talked to
      To escape, the player will have to pass by the portal.

    Please return JSON describing the objective of this level, the objects that should be placed as well as all enemies/npcs that shall be placed:
    
    {{"objective": str, "objects":list[OBJECT], "enemies":list[ENEMIES], "boss":list[BOSS],"npcs": list[NPC]}}
    In all of the following example, placement is the id of the room to place the object in.
    # The Objects that should be placed in the treasure chests
    OBJECT = {{"name": str, "description": str,"placement": int, "strength": str, "speed": str}}
    # The infos necessary about the enemies
    ENEMIES = {{"name": str, "placement": int}}
    # The NPC that should be added to the map
    NPC = {{"name": str, "persona": str, "placement": int}}
    # The Boss monster of this level.
    BOSS = {{"name": str, "placement": int}}

    For objects, the name key represents the name of the object inside the treasure chest
    when placement is requiered, it is the id of the room on the map.
    
    All fields are not necessarily required; if null, don't add it. it should make sense with the crafted story.
    Items can only be weapons or objects that can be useful for a special quest. "strength" and "speed" should only be declared for weapons and can only range between 0 and 1. 0 being a rusty sword and 1 being the best sword in the game.
    
    Important: Only return a single piece of valid JSON text.
    
    Here is the map:
    
    {myMap}
    
    X: is the starting position of the player
    ?: represent and interesting room where it could be interesting to place an object
    numbers represent the index of the room
    
    and the objective of this level: {story}
    The objective MUST be feasible, otherwise the player will be stuck.
    
    REMEMBER, You are ONLY allowed to only use the following elements and not modify either the map or the enemies:
