Thank the gods that a great designer has souped-up gaming’s most famous kaiju. The lore and crunch contained within this tome redfine this sack of hit points as a being to build entire campaigns around.

On using the tarrasque: I never did because I wasn’t sure how the frack to use it, really. I read it and went oh my god that thing is just death on wheels, holy cow it’s just a mindless horrible killing machine… After perusing the overview Encoded Designs gave me, I want to run a ********* Tarrasque game.

– Bruce Cordell, D&D Designer, The Strange

The Tarrasque is one of my favorite monsters that I’ve never used in a game. I like the story elements it brings, but managing the mechanics is daunting. The Book of the Tarrasque delivers more than just practical advice. It delivers confidence, which is one of the most important things a GM needs.
– The Caleb G, The RPG Academy

These guys have finally given the Tarrasque some teeth!
