Map of Illusions and Secret Doors (Magic Map)

This map functions as a combination of a map of illusions and a map of secret doors, with a single charge either detecting illusions, invisibility, or secret doors, or dispelling invisibility on an object or being. This particular map has 10d4+10 charges. When all the charges have been expended, the map explodes, causing 1d12+10 points of damage to each person within a 10-foot radius (save vs. spell for half damage, except for the user who takes full damage with no saving throw).
