There are two ways in the RAW to determine Cover for Melee attacks, one on page 280 of the PHB states:
Determining Cover: To determine if a target has
cover, choose a corner of a square you occupy (or
a corner of your attack’s origin square) and trace
imaginary lines from that corner to every corner
of any one square the target occupies. If one or
two of those lines are blocked by an obstacle or an
enemy, the target has cover. (A line isn’t blocked if it
runs along the edge of an obstacle’s or an enemy’s
square.) If three or four of those lines are blocked but
you have line of effect, the target has superior cover.
The other on pg 43 of the DMG states:
DETERMINING COVER FOR MELEE ATTACKS
Defender’s Burden: The target of a melee attack
has to prove that it has cover. That proof consists of
a line between the attacker and the defender that is
blocked by a solid object.
Corner to Corner: The defender has cover if an
imaginary line from a corner of the attacker’s space
to a corner of the defender’s space is blocked.
Getting Technical: If you need to be extremely
precise, choose a square the attacker occupies and
a square the defender occupies. Draw an imaginary
line from every corner of the attacker’s space to every
corner of the defender’s space. If even one line is
obstructed, the defender has cover. (A line that runs
parallel right along a wall isn’t blocked.)
Superior Cover: Only specific terrain features (such
as grates and arrow slits) grant superior cover from
melee attacks.
What I would like to know is how is your group handling it and or which version do you prefer via the poll. If you have a house rule please post below.
