@UKI36,
Warrior stones are from Storage Items -> Crafting at the bottom right.
Special use +# adds to the amount of times a hero can use their special.
It doesn't add to their army special uses.
You can see the maximum amount of runes that will stack in Manage Units -> Active Runes.
You can't go higher than the maximum that's shown in Active Runes.
Growth runes currently have a max of 3.
All runes have a minimum of adding +1 but there are more advanced runes that add higher amounts.
The True Growth Rune is +3 which will bring you to the max.
:)
