In the game, 2-4 players each take charge of one of eight legendary monsters — with a brief history of each one included in the rulebook — and in each round of the game you all call dibs on a new piece of land, strip that land of its resources, then (in all likelihood) take a swing at one another to dislodge an opponent from its land to claim that turf for yourself.
Combat is dice-driven, with everyone getting a baseline of dice with which to attack, combined with a puzzle of sorts as you want to fill lines on your monster board with runes in order to supersize your attack. You can use runes to give you a free reroll, to upgrade dice, to draw spell cards, to collect chi to power spells and recharge runes, and to use your ultimate ability, which is unique for each monster. Choose, collect, roll, pummel...score?
