Actually concealment affects all missions as a modifier. Try a steal research mission with 2 spies both at the same espionage level but different concealment levels, the one with higher concealment will have better odds.
After testing I would have to add some clarification to that conclusion.
Concealment modifies the main skill used rather than your overall chance to succeed. With two spies with 0 espionage skill, concealment made no difference whatsoever when attempting the same mission (that is with 35% concealment vs 0 Concealment). So, I would conclude also that when dealing with either low levels of the key skill in question or low levels of concealment it is of limited use. However an agent with a high key skill level will benefit from any positive amount of concealment, while an agent with a very high concealment should be noticeable better at anything he is also skilled in. A high concealment level however will not help the agent one bit if he has zero skill at the whatever it is he is attempting.
Of course that could well be what you meant, but I read it to mean it modified your overall chance so thought I should add clarification. If a character only has concealment as a skill then he is next to useless (unless he's going deep undercover).
On a side note, I suspect concealment may make agents harder to be captured too, but this is more problematic to test.
Sounds right to me. I just knew that having a high concealment skill helped in missions, and knew it acted as a modifier just not sure exactly how. Seems your little test may have revealed how it works.
