Mechanicum Protectiva

A model with a Mechanicum Protectiva gains a 4+ Invulnerable Save. Invulnerable Saves granted by a Mechanicum Protectiva do not stack with other Invulnerable Saves, but can benefit from rules (like cyber-familiar) that specifically increase existing Saves. If a model has another Invulnerable Save then the controlling player must choose which one to use.
