Dice pool

A dice pool is a number of dice available to a character attempting an action, and is a concept used in all of White Wolf's game systems.

Dice pools are usually determined by a character's traits, most often a combination of relevant Attribute and Ability. For example, when attempting research at the local library, the dice pool would likely be a number of dice equal to the sum of the character's Intelligence Attribute and Investigation Ability. Sometimes other traits, like supernatural powers (e.g. Disciplines, Sphere or Arcanum ratings), may be used instead, either instead of an Ability or, in the Storytelling System, in addition to the other two traits. Some other traits, like Willpower, Humanity or Virtues, may also be rolled under certain circumstances, though these are rarely added to other traits.

In the Revised Storyteller System used by the Trinity games and Scion, dice pools for most tasks were pre-figured by adding together set combinations of Attribute and Ability. In all other versions of the system, the Storyteller arbitrates the most appropriate combinations, though the Storytelling System features rules which dictate the dice pools for many tasks.
