To attack a monster in True Dungeon, you must slide a weapon counter 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 will be 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 is to simulate the chaos of battle and how combatants can affect each other's attacks. Damage is determined by the direction the numbers on the weapon counter are facing in relation to the damage indicator on the combat board. So, your damage is randomized as you slide your counter. It makes for some very exciting combat!
Note that Fighters, Rangers and Paladins will have a chance to practice on a sample combat board before the actual adventure, while all other classes will not. This simulates the advantage the fighter-types have in D&D.
