* An attribute of 0 can normally only result in a 0 (see [[#Pips]] below).

And that's it.  When using dice, you can either count odds as failures and evens as successes, or count the lower half of results as 0 (1-3 on a d6, 1-5 on a d10...) and the upper half as 1 (4-6 on a d6, 6-10 on a d10).  In [http://www.openrpg.com OpenRPG], roll [(Attribute)d2-(Attribute)] to get the appropriate result.  I will also be providing a roller with a modified 'd1' that generates 0's and 1's accordingly.

* An attribute of 1 can result in a 1 if the result only comes up 'tails', or a 2 if 'heads'

For game masters who wish it, if a test generates no successes when the difficulty was greater than half the player's pool (difficulty 2 on 3 coins, 5 on 8, etc), the test can botch, resulting in mess happenning.
−
This results in a pretty steep difference between a score and its predecessor (a score of 2 will beat a score of 3 only once every thirty-two tries).  To mediate this, a single [[#Attributes|attribute]] rank can be divided into three pips, as follows:
 
−
 
 
−
* The first pip only flips a single coin.  It does not count as a rank for the purposes of adding to the result.
 
−
* The second pip does not flip a coin, but instead counts as a rank for the purposes of adding to the result.
 
−
* The third 'pip' grants the full rank bonus.
 
−
 
 
−
In [http://www.openrpg.com OpenRPG], the first pip should be recorded like ''1d2-1+'''score''''', and the second pip ''1+'''score''''', when making use of macros and such.

In other formats (or simple records), use '''''score'''+h'' for the first pip and '''''score'''+1'' for the second pip.

=== Teamwork ===
 
−
The game master must decide whether or not teamwork can apply to a specific situation.  While the rules are specific to each take on the [[d2 System]], all takes are meant to handle it somewhat like what follows:
 
−
 
 
−
A given [[#Attributes|attribute]] is considered the cooperation [[#Attributes|attribute]].  This score limits just how much the 'leader' can benefit from her fellow teammates.  This same [[#Attributes|attribute]] likewise limits just how much her teammates can contribute to her effort.
 
−
 
 
−
This affects the quality of a given result.  Affecting the quantity, of course, is a much simpler process (two people can do twice the work, for example).

Basics

The d2 System is a role-playing system that can be used with nearly any kind of dice, from coins to standard six-sided dice to d20s, as long as it has an even number of sides. I am using it as the basis of Exalted Lite, Forgotten Dawn, and Solar Storms.

Because it only uses a d2, I will be referring to 'flipping coins' where most other systems will involve rolling dice. When rolling dice, the easiest thing to do is consider an even number a success ('heads'), and an odd number a failure ('tails'). Feel free to use another means if it suits your group.

This isn't a normal generic system, since it cannot be used in a standalone fashion. For examples, see Forgotten Dawn, Exalted Lite, and Solar Storms. Each uses these rules as their core, but expands upon them by defining their own attributes, and the subsequent rules from them.

Test

The core of making a test in d2 is to flip your attribute in coins, counting heads as 1 (a success) and tails as 0 (a failure).

And that's it. When using dice, you can either count odds as failures and evens as successes, or count the lower half of results as 0 (1-3 on a d6, 1-5 on a d10...) and the upper half as 1 (4-6 on a d6, 6-10 on a d10). In OpenRPG, roll [(Attribute)d2-(Attribute)] to get the appropriate result. I will also be providing a roller with a modified 'd1' that generates 0's and 1's accordingly.

For game masters who wish it, if a test generates no successes when the difficulty was greater than half the player's pool (difficulty 2 on 3 coins, 5 on 8, etc), the test can botch, resulting in mess happenning.

Advanced Rules

Most of the d2 Systems rules have to remain pretty basic, due to the level of customization needed. There are a few common themes which follow identical or similar guidelines, however.

Scaling

A feature of the d2 System is the ability to scale, where a group of two or more coins can be counted in a single coin. This mostly comes into play in settings like Solar Storms, where the vast difference between capabilities needs representation.

Scales are assigned a letter, from A to Z. Human scale is considered to be scale B. Each scale is considered to be ten times as good as the scale previous. For example, a score of 10 on scale C would be only be a score of 1 scale D, but a score of 100 on scale B, and 1,000 on scale A.

Attributes

Attributes in the d2 System are a part of the customization of the system. While they should be comprehensive, they should also be a short list:

Exalted Lite Forgotten Dawn Solar Storms
Awareness Awareness Acceleration
Compassion Brawn Coordination
Conviction Control Dissipation
Creation Craft Durability
Essence Create Mobility
Expression Destroy Perception
Harmony Expression Processing
Intellect Harmony Reason
Might Knowledge Resilience
Natural Maintain Size
Prowess Perceive Volume
Stature Prowess
Subterfuge Soul
Temperance Stature
Valor Subterfuge
Warfare Warfare

These aren't the sum total of their systems, of course. Solar Storms has its Personality Matrix, they each have an extended set of individual rules.
