A 6-pack of Viking Helm patterns! This helm is classified as Plate Heavy Armor. 

Patterns are consumable items that are used in the crafting system to reshape the visuals of an existing item while preserving the functionality and data associated with that item. Each pattern can be used exactly once and then it is consumed.

Reshaping with patterns will be restricted to the item type so that you can only reshape a helmet using a helmet pattern, or a 2-handed sword using a 2-handed sword pattern (i.e. you can't make a 2-handed sword look like a dagger).
