Concealment

Concealment is a situation that occurs when a character is hard to spot because of environmental effects such as darkness, smoke, tall grass, or mist. Concealment imposes penalties on ranged attacks and sight-based skill checks such as many Perception checks. Conversely, it can provide bonuses for checks on other skills, such as Stealth.


The exact bonuses and penalties can be modified by the GM if needed. However, in general, concealment can be divided into levels based on how obscuring the concealment is. See Table I.6–7: Concealment for examples of different types of concealment. In each case, the type of concealment adds a number of b equal to the “Dice Added” entry to any ranged combat checks, Vigilance checks, or Perception checks against targets with concealment. Conversely, it adds a number of b equal to the “Dice Added” entry to any Stealth checks made by a character with concealment. These Boosts or Setbacks may also be added to other skill checks if the GM feels it’s appropriate.
