Cover
-----

Walls, trees, creatures, and other obstacles can provid
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 narro
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.
