"You sneak into a museum filled with all sorts of strange displays, from fierce weaponry and intricate jewelry through to demonic statues and a strange obsidian monolith. You begin to take a couple of steps towards the monolith when darkness swirls around you as the museum's protections jump to life..." This is a one-shot heist adventure in which the players must infiltrate a high society event and steal a powerful magical item from right under the nose of an accomplished wizard. They will encounter mind-bending illusory defenses and compete with a secondary heist party, all while avoiding the gaze of the guards. This adventure is for four level 5 players (though adjusting for 3-6 players would be minimal effort) and is expected to take around five hours. It includes: * An exciting heist with several twists * Two new heist-based mechanics: Flashbacks and Guard Alert Level * Two optional objectives for the players to complete * A new monster to fight: the shadow duplicate * Two new items: the rod of illusia and the jade figurine of the deinonychus * Simple rules for running a skill challenge * Detailed maps of the manor as well as schematics for planning
