In order to properly describe combat Id like a clearer understanding of what it look like when a player in plate armor takes damage.
PHB 5e. Plate consists of shaped, interlocking metal plates to cover the entire body. A suit of plate includes gauntlets, heavy leather boots, a visored helmet, and thick layers of padding underneath the armor. Buckles and straps distribute the weight over the body.
That seems very durable. Does an enemy mace dent the armor and hit the person within? Can a sword pierce the plate?
How do you see your DM describing a character in full plate taking a damaging hit?
