Spirit Armour (Necromancy)
Level: Mage 3
Mana: 30. Persistant. No bonus damage. Base Success: 100%.
  Forges a protective shield out of your own life essence, giving you defenses similar to plate armour (9 + 1/3 caster levels armour rating) but costing you 3d6 of your own hit points. Spirit Armour counts as hwavy armour for the purposes of abilities like Defensive Roll, and is not compatable with mundane physical armour.
