Game modes
Pick a game above the dice tray, or jump straight to one:
- Marvel Multiverse RPG — d616. Two d6 and the Marvel die, with your ability score, a target number, edges and troubles, and damage from your multiplier. Fantastic and Ultimate Fantastic results are called out for you.
- EZD6. One d6 against a target, with boons and banes, exploding sixes on attacks, magic rolls of one to three dice, and a reminder of how much Karma would turn a miss into a success.
- Call of Cthulhu. Percentile rolls against a skill with bonus and penalty dice, Regular, Hard and Extreme successes, criticals, fumbles and pushed rolls.
