Map of Mapping and Secret Doors (Magic Map)

This map works like a map of secret doors with 20d4 charges. When the charges are gone, there is an 85% chance that the map becomes a map of mapping (10d4 charges) and a 15% chance that the map explodes, inflicting 2d4+2 points damage to each person within a 10-foot radius (save vs. spell for half damage).
