|Like many fantasy computer roleplaying games, Dungeon Siege II features a super-secret area, involving tricky tasks and being observant. In order to get to the secret area, four "Mysterious" items are required: A Stone dropped by the Loot Thief, a Token from the spoils of overcoming the tenth and final round of the Arena, a Book after tediously collecting all other in-game books, and a Bucket in a secret location. Once all four items are gathered, the party can teleport to underground ruins to begin the perilous journey through a strange area.
||The so-called Loot Thief is a hunched fellow who sometimes appears and is labelled "???" when very valuable treasure is left behind by defeated monsters. He sticks around only for a short time, running about the battlefield and stealing items whenever he is in contact with a party member. If struck during that time, he retreats and drops a goodie from his bag. If not defeated within his short appearance, he escapes. If he can somehow be quickly defeated, he drops a "Mysterious Stone".
