Map of Mapping and Magic (Magic Map)

This map initially functions in all ways as a map of magic. After 20d4 charges have been used, however, the map has an 85% chance of becoming a map of mapping (with 10d4 charges) and a 15% chance of exploding in magical flame, causing everyone within 10 feet of the explosion to take 2d4+2 points of damage (save vs. spell for half damage).
