I got a suggestion.
It is pretty boring just having a chest plate for clay soldiers. So I implemented this type of thing,
Putting a leather into your crafting thingy will allow you to have "small leather" which is used for the helmets of the Clay Soldiers.
1 Leather - 4 Small Leather
Now there is a new type of weapons I want to introduce to you as well. The spears!
Just put 2 sticks in the crafting thingy and you will get a miniature spear.
