A Cinematic bestiary for busy GMs. 25 Homebrew Monsters with full lore, variants, lair actions and legendary options where they fit, plus 25 plug-in encounters that drop straight into your game.

The Vault of Monsters is a chunky paperback, a little over 100 pages, packed with original creatures and drop-in encounters. Built for 5e, written for busy GMs, it’s the kind of book you’ll keep within arm’s reach. Clear stats, usable lore, tidy tactics, plus selected battlemaps where it really sings.

Unique Monsters: Discover 25 unique creatures that can't be found in any official manual, from the sinister Crypt Stalker, the enigmatic Puddle Jumper, and many more.

Detailed Lore: Each entry includes rich backstories and lore, adding depth and flavour to your encounters.

Dynamic Artwork: Stunning illustrations bring each monster to life, sparking the imagination and setting the scene for epic battles.

Balanced Mechanics: Meticulously playtested stats and abilities ensure that each monster offers a fair but challenging encounter for players of all levels.

Ready to run encounters: Get 25 unique Encounters for those monsters in a drop-in format, with clear objectives, twists, outcomes, optional complications, plus safety flags and content notes where they help.
