Do NOT upgrade your items

If you have to, leave them at +1, do NOT go any higher. At the rate this game breaks your gears, upgrading your gears is a death sentence to your character. You will go back with a full loot of gears and you will lose gold repairing, you will not make any profit.

I made a mistake upgrading several pink items to +3, and I am not making any profits, so it's GG for me.
