Back on BiosFear, I spent 540 Emeralds on my Scream +5. Not sure what you are talking about but failing with farmed Items was absolutely what this game was about.
So you spent in all this years 540 trys? Well That is OK. Just calculate yourself how long does it take to try building the weapon 540 Times.... About 20 years??
You can not compare to up or to build a weapon. Weapon fail = still have one even lvl 0
Build fail = got nothing
After Farming items for months!!!
