Crystal CapacitorEditYou have found of a way of restoring the vis absorption
Each crystal capacitor can store up to 100 vis and will slowly absorb or release vis if nearby nodes are above or below their baseline levels. It can only absorb or release 1 vis every 5 seconds.
Research for a Crystal Capacitor is: Vitreus, Praecantatio, and Permutatio
The capacitor can be safely moved without losing any stored vis.
