I set this adventure up for 2 players and noticed that there are no monsters in the bottom left and bottom right rooms for two players. I also read in the scenario that the monsters in the central room cannot enter or use line of sight for ranged attacks over the obstacles. So if there are two players and one player starts in the bottom left and the other in the bottom right then they will simply just need to walk to the chests and loot them. That seems far too simple. Am I missing something here? Is this an adventure for two players with potentially no combat?
