Concealment provides defense against melee attacks, ranged attacks, melee touch attacks and ranged touch attacks. It also provides defense against some active combat feats such as Knockdown and Whirlwind Attack, however it does not defend against Feint, Disarm, Seeker Arrow, One Shot or Tenacious Plague.
Concealment is applied as a chance to miss based on the level of concealment. Whenever an attack roll is made against a concealed target which would normally hit (ie, the roll matches or exceeds the target's armor class), a d100 is rolled. If the result of the roll is less than, or equal to, the concealment value, the attack misses.
The most common level of concealment, and the PnP maximum, is 50%, however spells like Ghostly Visage and Ethereal Visage provide lower values of concealment. The toolset allows for 100% concealment, so in theory one may also find higher levels of concealment in community modules.
