Concealment

Concealment includes all circumstances in which nothing physically blocks a blow or shot, but something interferes with an attacker’s accuracy.

Degree of Concealment

Concealment is subjectively measured as to how well concealed the defender is. Examples of what might qualify as concealment of various degrees are given in Table: Concealment. Concealment always depends on the point of view of the attacker.

Concealment Miss Chance

Concealment gives the subject of a successful attack a chance that the attacker missed because of the concealment. If the attacker hits, the defender must make a miss chance percentile roll to avoid being struck. (Actually, it doesn’t matter who makes the roll or whether it’s rolled before or after the attack roll. When multiple concealment conditions apply to a defender, use the one that would produce the highest miss chance. Do not add the miss chances together.

Table: Concealment
Concealment (Example) Miss Chance
One-quarter (light fog; light foliage) 10%
One-half (shadows; dense fog at 5 ft.) 20%
Three-quarters (dense foliage) 30%
Nine-tenths (near total darkness) 40%
Total (attacker blind; total darkness; smoke grenade; dense fog at 10 ft.) 50% and must guess target’s location
