Cover

When there is not a clear line of sight for a ranged attack, there are enemies or allies in the way, or the target is adjacent to a wall, you automatically benefit from Passive Cover against ranged attacks.

Passive Cover will grant you a CM to your Basic Body Defense against Ranged Attacks:

• Passive Cover - None: +0 (No obstruction.)
• Passive Cover - Lesser: -1 (Creatures on the way, 1m-tall obstacle, etc.)
• Passive Cover - Standard: -3 (Line of sight is blocked by the corners of obstacles.)
• Passive Cover - Greater: -6 (Line of sight is almost completely obstructed.)

If the line of sight is completely obstructed, obviously the attack cannot be performed at all (regardless of the Disregard Cover feat).

Note that on top of the Passive Cover, a target might want to react with the Take Cover reaction when applicable.
