Couter
Medieval History
The couter is the defense for the elbow in a piece of plate armour. Initially just a curved piece of metal, as plate armor progressed the couter became an articulated joint.
In fighting reenactment groups such as the Society for Creative Anachronism, a couter is often called an elbow cop.
In Belegarth
Class 1: Blue Armor confers one additional hit to the Target Area covered by the Armor, so a single hit from a blue weapon 'breaks' the armor, and an additional hit kills the Target Area underneath.
Class 2: Red Since armor only provides one additional hit to the covered area, this allows class 2 weapons to functionally ignore armor.
Class 3: Green A two-handed strike from a green weapon causes two hits of damage against a Target Area, ignoring any Armor the Target Area may have. A one-handed strike causes no injury to an Armored Target Area.
Class 4: Yellow Class 4 (missile) Weapons cause two hits of Injury to a Target Area, this allows class 4 weapons to functionally ignore armor.
Class 5: White Since the only legal target zone for these weapons is the head, it does not provide any benefit aside from protection from personal injury.
