Walls, trees, creatures, and other obstacles can provide cover, making a target more difficult to harm. As detailed in the Cover table, there are three degrees of cover, each of which gives a different benefit to a target.
A target can benefit from cover only when an Attack or other effect originates on the opposite side of the cover. If a target is behind multiple sources of cover, only the most protective degree of cover applies; the degrees aren't added together. For example, if a target is behind a creature that gives Half Cover and a tree trunk that gives Three-Quarters Cover, the target has Three-Quarters Cover. Cover Table
