Concealment

Basic
Agility
Concealment is used whenever you want to hide from sight. To use this Skill, there must be appropriate terrain (trees, walls, buildings or some other obstacle) or some concealing effect like fog or darkness. Otherwise, the test automatically fails. Concealment is always an Opposed Test, in which you pit your Concealment Test against your opponent’s Awareness Test (or half their Perception if they do not have the Awareness skill). You need not Test Concealment when you hide, only when someone is looking for you. If you succeed, you remain unseen.
If you remain perfectly still, you gain a +10 bonus to your Test.
A Concealment Test is usually a Half Action.

Camouflage

Whenever you would attempt to conceal another character, you can Test Concealment and apply the results of your Test for that character. The effects of a successful Test remain only so long as that character has the benefit of cover, reduced visibility (fog, foliage, etc.), and does not move. If the concealed character moves, he is no longer concealed.

Sniping

Whenever you attack an enemy while successfully hidden, you automatically reveal your presence. You can attempt a Concealment Test as a Half Action to duck back under cover, but your opponents gain a +20 bonus to their Awareness Tests.

Taking Time to Hide

Normally a Concealment Test is a Half Action, representing you ducking behind cover or out of sight. However, if you take longer to conceal yourself, you have a better chance of remaining hidden. For every additional five minutes you take to hide yourself (or another), you gain a +10 bonus to the Concealment Test, to a maximum of +30 for taking 15 minutes to hide.
