The Composed System is intent as a modular and setting agnostic system that caters to a variety of settings & genres.
The intent is for this section to compose the basic rules of the system. More in depth rules will be found in the Setting section.
The Composed System defines the following types of action resolution: Automatic, Passive, Basic, Basic+Effect. The composed system allows for implementing these different types of action resolutions in a variety of ways. These are the actual dice rolled, and how to handle various modifiers and skill levels.
It is the duty of the game master to decide what type of action resolution to use at any given moment. Deciding on what type of action resolution to use for a given action is part of the action adjudication with forms the core of the role playing experience.
Automatic resolutions do not use dice. The game master simply decides if an action fails or succeeds. Automatic resolution should be used when there is no risk involved for the player, or when a task is impossible to pull off.
Passive resolution do not use dice. The game master compares a capability of a player character against a target number and if equal or above succeeds with the action. Otherwise he fails. Passive resolution can also be gauged the extent of a capability, such as determining how much a player character knows about some subject.
A basic resolution is composed of a single roll of one or more dice versus a preset difficulty, with or without modifiers. If your roll equals or exceeds the difficulty the action succeeds, if the roll is under the difficulty the action fails. Sometimes the degree to which you exceed or fail the roll determines how successful the roll is.
In Basic+Effect resolution you first roll a basic resolution to see if you succeed with an action. After that you roll an effect dice to see how much you progress towards a specific goal. The most common use of Basic+Effect roll is one roll to see if you hit with a weapon and a separate roll to see how much damage you deal. Should be used when a high degree of granularity towards a specific goal is required, or when you need to do multiple rolls over an extended period of time towards a single goal.
Action Dice: 1D10 + Attribute + Skill + Modifiers
Effect Dice: 1D10 + Modifiers
In order to succeed with an action you roll the action dice against a target number between 0 and 20. If the roll is equal or higher than the target number you succeed with the action. For some actions you may also roll an effect dice to see how well you succeed, or how far you got with the action. For these you roll the effect dice and either use the result as a measuring stick for how well you did or subtract the number from something that measures how well you did, such as Guard Points from an enemy, or Labor Points from some item you are trying to craft.
Modifiers can apply to both the Action Dice or the Effect Dice. However, for some resolution types you do not roll the effect dice and for some you roll neither. In these instances the modifier is simply ignored. It is assumed that if the roll succeeds the effect is sufficient to either complete the task or make adequate progress towards it.
Modifiers that do not affect action resolution - that is not applied to either the Action or Effect Die - are simply a number added or subtracted from what it modifies.
For action and effect dice the following modifiers apply:
Modifiers of the same type does not stack. If three separate sources would give you a +2 modifiers, you still only get +2, not +6.
Positive and negative modifiers of the same type negate each other. A +2 and a -2 means a +0. Disadvantage and Advantage means neither.
If you ever need to apply Disadvantage or Advantage to a roll but are not rolling them as dice you may instead apply -3 and +3 to the roll.
