"Welcome, my contenders! Welcome to the Thirteen Trials!"

Felicity, Ben and Mark find themselves summoned by different gods in a strange world and sent on an even more bizarre mission: retrieve the 'Hammer of Creation' stolen by the God of Mischief because he was... bored?

Apparently fed up with 4,000 years of the same jokes and pranks, the renegade god is holding the universe hostage and running a series of dungeons strictly for his and his followers' entertainment. Thrust into the latest annual intake of 6,000 summons competing to win the Thirteen Trials, the earthlings must quickly level up their patronage systems to build upon the innate attributes they were apparently hand-picked for.

Navigating unwritten rules and an odd deja vu with many earth-based RPGs, the summons also have to contend with working alongside radically different humans from other worlds to solve level puzzles and defeat world-quest bosses.

Topping it all off, it seems the rules are set to change at any moment courtesy of their biased Dungeon Master, who might just have a penchant for mischief...
