Thanks you for playing our game!
Due to limited time the instructions of the dice mechanics are on the game page.
The short version is that you roll dice (and reroll some or all of them in the Dice Phase) trying to get a combination of values needed to activated attacks in the second phase where you select the values needed in order to activate an attack.
For ex. if you rolled two 6 in the dice phase you selected them in the action phase in order to enable the basic attack action allowing you to select it in order to deal 1 damage to 1 enemy. Same with the other attacks.
It use a push you luck mechanics. Do you keep (for ex.) the 6 you rolled or do you roll them trying to get die values needed for the better attacks?
