The Sundered Throne
Most rolls in the game consist of a dice pool that is made up of one of the character’s attributes and one of the character’s skills. The number of the attribute and the number of the skill are added together, and that many ten sided dice are rolled.
Each die that comes up a 8 or greater is called a success. Only one success is needed for most rolls. More successes indicate a greater degree of success at the endeavor. Five or more successes are considered an exceptional effort, much like a ‘crit’ in other games.
For instance, when attempting to seduce a date, a player might roll Manipulation + Subterfuge, if doing so dishonestly, or Presence + Socialize if doing so in an honest manner. Given a Manipulation of 3 and a Subterfuge of 2, the player would roll five dice.
The 10 again rule:
When a 10 comes up on a die, that die is rolled again. If it comes up a success a second time, then an additional success is scored on the roll. If it comes up a 10 the second time, then it can be re-rolled yet again, until no more 10s are rolled.
Some powerful weapons, exceptional luck, or enchanted endeavors will allow a player to re-roll on more than just 10s. In this case the roll is said to benefit from a 9 again rule, or even an 8 again rule, where every die that comes up a success is re-rolled until it no longer comes up successes.
Most rolls worth using dice for will be resisted in some way. The security guard resists an attempt to fast-talk past him with his Composure, the chess opponent resists an attempt to set up a trap for him on the board with his Intelligence, and most attacks in combat are resisted by Defense.
In this case, the number of the resisting attribute is subtracted from the die pool. So if the Security Guard has a Composure of 2, he subtracts 2 dice from the Manipulation + Subterfuge pool of the fast-talker. If the original dice pool was 5, the player now rolls only 3 dice.
Sometimes both parties are actively working toward a goal that only the first person to succeed will achieve, or otherwise actively contesting each other. In this case, a contested roll is used.
Both parties determine their dice pool, sometimes these pools are used without being reduced by resistance, and sometimes resistance is used. In either case, both parties roll, and accumulate successes.
The contest is settled when one party has reached a pre-arranged number of successes, if the action is to take several rolls to resolve, or the winner is determined by whoever scored the most successes, if the action takes only a single roll.
