Stat

A Statistic (or Stat) is a number associated with a character that measures their ability in a certain area of application.

Primary Stats cannot be derived from anything else, being the source of all other Statistics. That is in contrast to Derived Stats, which are calculated via formulae from Primary Stats.

The Primary Stats in the D12 System form a ternary tree featuring a trickle down mechanism, and starting with your Level as the root statistic. Your Level then divides into 3 Realms: Body, Mind and Soul; and they combined branch to the 9 Attributes (STR, DEX, CON, INT, WIS, CHA, DIV, FOW, LCK). Finally, the 9 Attributes branch into 27 Skills.

The way the trickle down works is, for every point you earn on a node past the first, you get to propagate that point to one of the three children. So at Level 1, every single adventurer has the same attributes (bar racial, class and feat bonuses of course). But when they level up to 2, they get to propagate to the Body/Mind/Soul tier, and thus make their first attribute choice. On Level 3, you can propagate to the same node as before, doubling down on one of the 3 realms, and getting to propagate again, or you can generalize and pick a second realm to focus on.

The way modifiers work is that you always roll the most specific check you can, normally a Skill check for skills or a Basic Attribute for core game actions (such as attacks); your modifier on each node is based on its value and the values of the parents. Use the built-in character sheet editor to easily fill up your tree.

Note that you shall very rarely need to use modifiers for nodes other than Attributes and Skills. The final value of a node is also subject to a Level cap: the final node modifier (before applying any external modifiers) is capped at your current level. That means there are diminishing returns to over-specializing, and players are encouraged to have at least a minimal level of spread.

Derived Stats

Derived Stats are based on formulae over the primary stats.

You have 5 Resource Points that are derived from your stats:

Heroism Point : Represents a character's heroic potential in the narrative. Each character has a maximum number of Heroism Points equal to their Level value.
Action Point : Represents the amount of effort a character can expend in a given turn. Each character has 4 AP per round, refilled at the end of their turn, which can be used to perform different Actions.
Vitality Point : Represents a character's physical ability to keep going during intense situations. They are analogous to Health in other games, but in the D12 System, you only take real damage after you are Incapacitated. A character has a maximum VP equal to 4 + Body modifier.
Focus Point : Represents a character's mental vigor and ability to focus during intense situations. They are analogous to Mana in other games for Arcane casters, but they are also used by any characters to power special abilities that require focus, mental acuity and concentration. A character has a maximum FP equal to 4 + Mind modifier.
Spirit Point : Represents a character's morale and spiritual strength. They are a different form of Mana (for non-Arcane powers) or a form of mental stress or morale in other games, but they are also used by any characters to power special abilities. A character has a maximum SP equal to 4 + Soul modifier.

Other derived stats include:

Initiative = Awareness + Agility, used to determine order in combat via an Initiative Check
Movement = [3 (humanoid base) + Size Modifier + (Agility / 4) (rounded down)] hexes / turn
