For simplicity, the base rules assume whole-body protection from a particular item of armour. You may, of course, add your own rules relating to armouring of particular body parts.
Only one type of body-armour can be worn at any time. Shields, helmets, etc. can be worn together with body armour, but only one of each at a time, of course!

Description: A light but solid helm to protect the head. These are often depicted with animal horns attached in children's stories and the stage-props of theatrical plays, however horns are not normally a part of the equipment as having handles for enemies to grab, or to direct weapons blows strait into the head are a pretty stupid idea!
