The Mage Hand spell is indeed sufficient. As soon as the bag leaves the table, there is an audible click, and all of the traps start retracting, resetting themselves. That would have been really unfortunate for a normal fighter-type who would have wandered up and had no way of teleporting back. Really unfortunate.<br/><br/>Luckily, Ancalagon is quite safe, and has... a gold tube, with a sphere of jade used to plug it. Once that is removed, a rolled up scroll, as smooth as silk, can be extracted and examined. At the top, it reads "Observations of Shaudi the Conqueror", and contains the following spells:<br/><br/>Crushing Despair (4th)<br/>Scintillating Pattern (8th)<br/>Shapechange (9th)<br/>Power Word: Kill (9th)<br/>Refuge (9th)<br/><br/>Quite a swindle, considering it cost a cantrip and a 1st level spell.
