A rogues gallery of boss monsters is on the loose - round ‘em up in this 250+ page book!

Say hello to the squabbling duo Pork and Bean, Blrrk the sentient ooze mob boss, the twisted tooth-fairy the Prince in Ivory, and the soul-stealing celestial Imryss plotting diabolical schemes.

And don’t forget the world-ending threats like Harathos the Bound God and the deep horror Vellai-Axal.

All these bosses and more are dying to defeat... I mean... meet you.
