Hi I being killing monster and the highest class i can get is C+++. How i'm i suppose to get B class and higher? (except for buying it from other people)
And how come some peoples weapons glow?

I THINK it is possible to get B and A from monsters...But, I've gotten my fair share of B's just from buying a million of the same item from the black market...

I think you can also just upgrade it...

you can make A items. I think thats the only way, besides the anni stuff. To make an A equipment, will require tons of gems, metals, and money. What you do is get your item you want to upgrade, and enhance till like lvl 8-9. Then add the type of gem you want in it. Now you have to make another item with highers stats on it. Then you combine them. The first item you enhanced should always be your base item. Dont ever combine that item to another one. So yea you do that over and over and over untill you get it to the point you want it at.

Dont do this until you get your very last equipment your gonna use. Doesnt have to be the last items, but for your character. The last items he your character will be using.

Enhancing

Spens: lvls 1-5
Mitchells: lvls 6-7
Yiternies: lvls 8 - maybe 9
TOB (Tears Of Blacksmith): 9-10

lol im spending like 20mil every time i get new eqs.. Black Market..

when ur ~140 dex it costs like 200k á wep.. and im trying till i get A+ :P

2 weps A+.. that takes a while

You CAN'T get As from the Black Market man. This is how they are found:

F: drops, Black Market
D: drops, store
C: drops, Black market
B: Boss drops, Black market
A: Boss drops
AA, AAA: Only through blacksmith enhance/combine or through in-game events.

You are spending huge amounts of cash on hopes. Maybe you would be better off if you would just store the gold and buy a good item in the end.
