Alptraum, if you would like...I could explain more about the gear modifiers over a voice chat. I can PM you my vent info if you'd like.

The info that Krugsmash mentions merely scratches the surface. There's a lot to explain, such as why you use purified fusion stones (cash shop item) vs. "non-purified" fusion stones (buy with gold), which items to use them on...etc. ... the difference between clean and dirty stones. Vahtos "matches"... High durability items...Enhancement runes...production runes...

Also, around level 45, you will be getting a TON of gear with Stamina X and IX, Dexterity X and IX, etc... It is VERY important that you hang on to these. You will make a lot of money if you pick the right ones. Stam is one of the most expensive clean base stats.

I would love to create a guide on this site which covers a lot of this, but it will take a while.
