You target one Region with this ritual. The Envoy of the Nation that owns that Region must be present for the entire performance of the ritual.
All allied Forces within the Region take -50% damage from all sources.
The effects of this ritual last until the end of the next Round of Downtime or another Regional Sorcery is placed on the target (whichever comes first).
You can overcharge this ritual; by increasing the Ritual Power of the ritual to 75, the ritual targets all Regions in a single Province.
If this ritual is performed outside of Veilguard, its required Ritual Power is tripled.
