The entire StoryTeller system is based on one single concept of dice rolling. Rather than rolling one dice and trying to get above a number, you roll a quantity of dice determined by some method against a difficulty determined by how difficult the task is. The number of dice that roll higher than that difficulty give you the number of successes that you roll. The number of successes that you achieve determine how well you did whatever.
Sounds complicated - its not.
For instance: if you have 4 dice, and attempt a difficulty 6 task, you roll those 4 dice against difficulty 6.
If you roll:

Characters doing stuff.
Normally when characters want to do something, the number of dice that they have to accomplish a task is determined by an Attribute+Ability pair. For instance, running after someone, you might pair together Dexterity and Athletics. Noticing that someone is lying to you might require a Perception and Subterfuge roll.
Eg: If Tom wants to convince Bill that he has indeed paid the Telecom bill, then Tom's player would check to see what ratings Tom has in both the Manipulation attribute and the Subterfuge ability. If Tom has a Manipulation rating of 2 and a Subterfuge rating of 3, this means Tom's player can roll 5 dice to try and lie.
The difficulty of any task is usually set by the GM. An average difficulty is 6, a hard task might have a difficulty of 8, while an easy one might be 4.
Eg: The GM decides that Bill normally trusts Tom, so the difficulty is only 4. Tom's player rolls his 5 dice...
Some examples of rolls
Complications
The most common use of willpower is to act as an autosucess. Before making a roll, you can opt to spend Willpower on the roll. The temporary willpower point is crossed off your sheet, and you start the roll with 1 sucess.
Eg: Tom wants to translate an ancient manuscript. Tom's player decides that it is fairly important to get it right, and spends a point of Willpower. Tom has a rating of 4 in Intelligence and 2 in Linguistics, so his player rolls 6 dice. The difficulty is 8, because the language is so weird. Tom's player rolls 1 4 8 9 2 5 5. Normally, this would mean Tom got 1 success, but with the Willpower expenditure, it becomes 2 successes.
The only roll that Willpower cannot be spent on in this fashion is a Willpower roll. All expenditures of Willpower must be declared before the roll.
Permanent Willpower is also used to avoid the effects of certain spells as they are cast upon you. To resist the spell normally, you need to roll your Willpower against difficulty 7 - each sucess that you roll cancels a sucess on the Spellcasting roll made against you.
Luck may be spent to cancel a rolled '1' after you have rolled dice, turning a failure into a sucess or a botch into a fail.
Eg: Tom's player is a bit annoyed with his roll to translate his manuscript, so he decides to spend a luck point to cancel the one 1. His roll is now 4 8 9 2 5 5 + Willpower = 3 successes, which is a quite a good result.
Luck can also be used to invoke Divine Intervention. The player rolls percentile dice and tries to roll under or equal to their permanent luck. Sucess means that a god (not necessarily their god, just a god) has noticed their plight and answers in a positive fashion (it suits their purposes, out of whim, because they were sleeping, whatever). Failure means the character loses a permanent luck. If you roll 00 this means that the god who noticed you is opposed to what you are trying to achieve and takes action accordingly.
Combat
Combat progresses as follows:
eg: Tom rolls his Wits + Alertness dice (5 dice) and rolls 1 3 5 8 6. He therefore gets 2 successes. Milya rolls her Wits + Alertness dice (3 dice) and gets 7 9 6. She therefore gets 3 sucesses.
Combatants using weapons roll either Dexterity + Melee or Dexterity + Missile Weapon, against the difficulty for their weapon. Brawling combatants roll Dexterity + Brawl to see if they connect.
eg: Milya's action was to try and spit a goblin with her sword. She rolls Dexterity + Melee (4 dice) and gets 3 7 5 8. Her sabre has a difficulty of 6, therefore she gets two successes. She connects.
Now her player rolls the damage for a sabre. Milya has a Strength of 2. A sabre does Strength + 4 dice of damage. Therefore Milya rolls 6 dice. She rolls 10 4 1 7 8 6, and then re-rolls the 10 which comes up as a 4, so 3 successes. The goblin rolls its Stamina (1 dice) and rolls a 4, failing. The goblin therefore takes 3 full Wound Levels of damage.
Dodging.
A character with dice left in their dice pool can declare a dodge at any time (even if they rolled 1 on their initiative and their attacker is moving on 3). Characters that have their action before an attacker can opt to save their move up to make a dodge instead of attacking.Multiple actions
Any character may opt to make more than one action in a single turn. At the start of the turn, the number of actions they intend to take is declared. If there is only one action declared, then it is resolved as usual.
However, if the character wishes to take multiple actions, the for the first action, they suffer a dice penalty equal to the number of actions, and for each following action, this dice penalty is increased by one.
For example: Milya opts to swipe twice at a goblin, a rather desperate attempt given her limited dice pool. She rolls 3 sucesses on her initiative roll. On her first action, she rolls Dex + Melee (4 dice) minus 2 dice (2 actions). On her second action, she would roll 4 dice - 3 = 1 dice only.
Spells
Spells take one time tick per level to cast. They are begun in the tick in which the character starts to resolve their action.
For example, Tom wants to cast Magic Missile. He rolls 2 successes on his Wits + Alertness roll, so he goes on 2. On 2, Tom starts his spell. It is a level one spell, so it comes off in 1 tick. On 1, Tom rolls his Spellcasting dice to determine the effect of the spell.
Spells always come off before people who botched their initiatives can do anything. A spell that has not been finished by tick 0 comes off then.
Eg: Bill wants to cast a Cure Disease spell. He too rolls 2 successes for initiative, and starts casting his spell on 2. Normally the spell would be finished 3 ticks later, but this would be below 0, so instead it is finished on 0. On 0, Bill rolls his Faith rating to determine the effect of the spell.
Armour
Armour is useful stuff. It makes it harder to do damage to you. But it has the disadvantage that it becomes harder to move in armour as well. In general, the more protection armor offers, the harder it is to move.
For example, wearing leather armour offers an extra dice to soak with. So if you are hit, you would roll Stamina + 1 dice to soak the damage. Leather is not too confining, so there is no real loss to agility.
On the other hand, plate mail offers an extra 4 dice to soak with. When you have damage inflicted upon you, you have your Stamina plus 4 more dice to roll to cancel damage successes. Conversely, your dexterity dice pool is reduced by 3.
If your dexterity is reduced to below 0 you can't move with anything resembling speed. You just don't have the natural togetherness to wear this degree of confining armour and do anything urgent, like combat.
NB Armour only works against biffing damage. It provides no extra defence to fire, lightning, magic, etc. Some enchanted armours may provide this kind of defence.
