Basically, I have a character that can manipulate Life-Force and she is also a swordswoman. Instead of wearing a metallic armour around her body, she uses Life-Force to protect herself.

Basically, her ability is generating aura that grants her Supernatural Durability and Selective Invulnerability. She can still be touched, but her aura defends her from damage. Something like Invulnerability via Aura Generation. Can this ability to considered as Life-Force Armour or must it be necessarily solid, so nothing could touch her?
