Hi
@Danlo! The enchantments are wonderfully useful things! Starting from the left....
1) This is your Power of Provision. You use this on your Workshops and supplies are boosted by 200%
2) This is an Enscorcelled Endowment. This will provide you with boosted Culture on a Cultural Building of your choice
3) This is Magical Manufacturing. You can use this on any of your Manufacturies and goods will be boosted by 50%
4) Inspiring Meditation will give you a further 10 KP Bars that will last for a 48hr Period
5) Combining Catalysts are used to Craft items in the Magic Academy along with Spell Fragments
and lastly...
6) Teleportation Spell. This allows you to Teleport a building back into your inventory for use in the future if you don't want to sell the building. Keep in mind however that some buildings are unable to be Teleported.
When you wish to use them, just pop into your inventory and choose the enchantment you wish to use, this will then take you to your city and highlight the buildings that you can use these on. Each enchantment only works for a certain period of time, so ensure you keep popping back to gain the maximum benefit!
Hope this helps!!
