The Natar Book can be obtained by raiding Natar's village with chance of 0.01%
The Natar Book need to be consumed by clicking in Hero's inventory.
You only can use the spell once. Some of spells has a duration of effect time.

3. The King of Natars Book : By reading the book. you will be granted random troops from the Natar's army. (I do not know the balance number...maybe like 200 troops and randomed? but you can not get natarian emperor and settler). You can control the Natar's armies as offensive army / move to other village
4. The Witch of Black Forest Book : Once you use it on your Hero, Whoever player getting attacked (Normal mode) by you, will decrease their ALL production by 15% for 24 hours. You only able to use this spell to 1 enemy player's village only (The one you attacked in normal mode). (Effect duration : 24 hours)
