Hi
@Blaris The Sorceries Tab was recently introduced to the Game. This is where the Tomes of Opulence are held, and where you can redeem them.
If you're not familiar with Tomes of Opulence, again these are a recently new feature. They are currently found in our Events. When acquiring a Tome, they may contain a choice of Supply Instants, Coin Instants, or Ancient Knowledge. They can also contain a choice of Evolutions for our Evolving Buildings.
When making your choice, the Tome is then redeemed for an Instant that can be found in your Inventory.
I hope that this has helped!
Kind Regards
Herodite.
