Here are the rules for "Going Loud"
Going loud allows the demon to completely heal any lethal or bashing damage and shrug off any Tilts affecting her. In addition to this, when the demon goes loud, her current Cover is lost; she replenishes all her Aether, her Primum is set to 10, and she gains access to every Embed her Incarnation gives her affinity for along with all Exploits. Changing this way does not require a normal compromise roll, since it constitutes the ultimate compromise of completely destroying the demon’s current Cover.
and Rules for additional pieces of Demonic Form
At Primum 3, the demon gains a fourth Modification. At Primum 6 the demon gains a third Techonology, and at Primum 10 the demon gains a second Process.
When a demon goes loud do they gain the additional pieces of the demonic form as if they had attained a natural Primum 10?
