Mystic Summoner

Some say they are spirits of dead architects, other say they are simply mischievous spirits that have yet to take physical form. In either case it is clear they are able to manifest physical traps in dungeons. Seasoned dungeon raiders have learned to expect traps anywhere even in previously explored rooms. It is rumored that the Mystic Summoner has control over the dungeon itself, able to expand the dungeon by their will alone.
