Item Upgrade
Upgrade Tokens are a powerful and permanent source of boost you can upgrade your gear with.
They can be obtained through the store or through a variety of bosses. 
Every upgrade represents:
- +3% damage boost for weapons
- +1 armor for any other equipment piece.
Every attempt has 70% chance of success and you can upgrade your item from +1 until +15.
To upgrade your gear, just click on your upgrade token and then on the item you wanna upgrade.
Upgrade Tokens Remover
You can retrieve back your upgrade status by using a Upgrade Token Remover. 
You will receive back perfect upgrade tokens 
instead, which can be used on any item with a 100% success chance.
If your equipment is upgraded until +14, for example, you will receive 14 perfect upgrade tokens.
All you must do is: click on the remover, and on the item you wanna extract.
