What is TerraClash?

About TerraClash, from BoardGameGeek:

Right then, adventurer! Tired of epic campaigns that fizzle out before you even find a decent tavern? TerraClash is the legendary quest you can actually finish in a single, glorious night. It's a tale of cards, dice, and uneasy alliances for 1-6 players. Dive in solo, team up with your mates, or have a proper free-for-all where backstabbing is practically encouraged. There is also a long campaign option for those who love an epic adventure, with downloadable character sheets and rule customisations to suit. In a nutshell, TerraClash is a "micro-campaign" that blends classic role-playing with fast-paced, competitive dice-rolling and deckbuilding action. The goal? Be the first hero to gather 8 Terra Coins, defeat the final Champion, and claim eternal glory! -description from the designer
