After the "Alchemy" science is studied, the new tab - Alchemy - will appear in the Vault window.
The "Alchemy" science allows:
1. making buildings "perfect";
2. making Artefacts "perfect";
3. stealing magic Crystals.
1. Perfection of buildings#
Some buildings, upgraded to the maximum level, can be perfected.
"Perfect" buildings have improved parameters and extra features.
For example, "perfect" military buildings produce certain number of units once a day.
When you click on a building of level 7 (or Tavern building of level 1) that can be perfected, you will find the "Make building perfect" button instead of the usual "Upgrade" button in the round menu of the building.
"Perfect" buildings are marked with a little crystal sign instead of the number showing level.
Perfection of a building can be added to the queue of construction.
Durability of the "perfect" buildings is 1 building's level higher.
In order to make a building "perfect" you will need resources, Black Gems, and
Crystals.
Crystals for perfection are taken from Heroes' Bags and from the "Vault" tab of the Vault building.
After the next upgrade Crystals will also be taken from the "Alchemy" tab of the Vault building.
Crystal are taken in the following order: from Bags, from the "Vault", from the "Alchemy".
2. Perfection of Artefacts#
There is the
Altar in the "Alchemy" tab of the Vault building.
There are 5 slots for Crystals of each type and 3 slots for Artefacts or Scrolls around the Altar.
And there is a slot for the Artefact you want to make "perfect" in the middle. If you place an Artefact in the slot you will be able to see the characteristics of the Artefact after upgrade.
Perfection of an Artefact requires 5 Crystals, 2 any Artefacts of the same level (with the one that is upgraded), and a Scroll.
Perfection is completed on clicking the "Make Artefact perfect" button.
"Perfect" Artefact costs more than similar not-perfect.
