Heavy Borean Armor Kit

Permanently increase the Stamina of an item worn on the chest, shoulders, legs, hands or feet by 8.

Attaching causes the item to become soulbound.

Armor kits fill the same virtual "slot" as enchantments and will overwrite any existing enchantments, or be overwritten by enchantments applied later.
