To attack a monster in True Dungeon, you slide a weapon token on a "combat board" resembling a shuffleboard. Your sliding piece must come to rest within certain areas of the combat board in order to hit the monster. Your coordination and nerves are tested, making this a really cool way to resolve combat. In addition, your battle strategies are tested because all attacks are made before any hits are determined. Therefore, it is possible to bump a team member’s weapon counter out of a non-hit area and into a hit area (or vice versa). This simulates the chaos of battle and how combatants can affect each other's attacks. Damage is determined by the direction the numbers on the weapon token are facing in relation to the damage indicator on the combat board. So, your damage is randomized as you slide your token. It makes for some very exciting combat!
Note that melee-focused characters have a chance to practice sliding on a sample combat board before the actual adventure, while all other classes may not. This simulates the combat advantage melee-types have.
