定义与来源
墙壁、树木、生物和其他障碍物都能提供掩护，使目标更难受伤。只有攻击或其他效应来自掩护另一侧时，目标才受益。多重掩护只取保护最强的一档，不叠加；例如半身掩护与四分之三掩护同时存在时，采用四分之三掩护。
**半身掩护：**至少遮住身体一半，使AC与敏捷豁免获得+2。低墙、大件家具、细树干或任何敌友生物都可能提供半身掩护。
**四分之三掩护：**约遮住身体四分之三，使AC与敏捷豁免获得+5；例如闸门、箭孔或粗树干。
**全身掩护：**身体被障碍物完全遮住，不能被攻击或法术直接指定为目标，但某些法术仍可通过效应范围影响它。

英文原文（SRD 5.1）
Cover
Walls, trees, creatures, and other obstacles can
provide cover during combat, making a target more
difficult to harm. A target can benefit from cover
only when an attack or other effect originates on the
opposite side of the cover.
There are three degrees of 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.
A target with half cover has a +2 bonus to AC and
Dexterity saving throws. A target has half cover if an
obstacle blocks at least half of its body. The obstacle
might be a low wall, a large piece of furniture, a
narrow tree trunk, or a creature, whether that
creature is an enemy or a friend.
A target with three-quarters cover has a +5
bonus to AC and Dexterity saving throws. A target
has three-quarters cover if about three-quarters of it
is covered by an obstacle. The obstacle might be a
portcullis, an arrow slit, or a thick tree trunk.
A target with total cover can’t be targeted directly
by an attack or a spell, although some spells can
reach such a target by including it in an area of effect.
A target has total cover if it is completely concealed
by an obstacle.
