A '''Praesidium Protectiva''' is a shield constructed from layers of armaplas and ceramite, and said to contain a shard of the [[Emperor]]'s own armour. As such it is highly effective against physical attacks, offering protection equal to a that of a [[Power Armour]].They are only found among the Adepta Sororitas, and even then are only issued to those Sisters who excel (and prefer to engage in) hand-to-hand combat. However some have found their way into the hands of [[Witch Hunters]].{{Fn|1}}{{Fn|2}}
