Unlocked at Headquarter 13, Statue Storage allows you to bank promising new statues without activating them.
Important: You can only place Sculptor Statues directly into Storage. Pre-existing, already placed Statues cannot be added!
Once a statue has been deployed, it can only be salvaged from there on. Doing so will give you Power Stones or Power Powder.
Storage Statues can be deployed to your base when needed, as long as you have not reached maximum Statue capacity.
