You target one Region with this ritual. The Envoy of the Nation that owns that Province (or that used to own it, if the Province has been Conquered by cultists) must be present for the entire performance of the ritual.
The Economy, Security, and Stability of the targeted Region are all reduced by 50.
All military Forces in the Region that are not benefiting from the Fortify or Harbor effects take 75 damage. All military forces that are benefiting from these effects take 50 damage instead.
All Military Units and Cultist Cells operating in the Region during this Round of Downtime take 20 damage.
Any cultural, logistical, economic, or magical sites or facilities located in the Region are temporarily shut down for at least the next Round of Downtime, and possibly longer.
Prismatic effect: If the mages performing this ritual have amongst their number mastery of both the Druathan and Vallarian Prismatica ritual lists, the damage dealt to the Region’s Economy, Security, and Stability and to friendly Armies and Navies is reduced to 25.
