Hello. Its been a while since I played 12sky, and currently I am lvl 20. Started again 3 days ago. I see many players enchanted, ad I kinda want to have enchanted items.

I don't mind having to grind or do anything to get materials, but tell me where do they come from? Are they monster drops, quest rewards? Cuz I only see tutorials about how to enchant, but not no how to get materials.

Sorry for the noobish question, please help a fellow player here.
Thanks in advance.  

well materials aka mats drop from mobs, but best way to get them is from Boses, as they always will drop mats. Ofc you can get some mats from quests too. from m1+ you can convert your CP in mats, lixirs, or rare/elite itmes at palace(its random drom) , each try will cost you 30 CP, and moustly you will get soe or goe.  

Best place to get mats is cave of darkness  

I think you can get there at lvl 50 or so. But you gotta buy Wrath of Centaur key from the herbist for 1m first :p Use that and you get 12 minutes in the cave, and you can tele there through guard captain.

When inside the cave, you can find 2 kind of monsters there; Vicious Centaurs and Vengeful Centaurs. Vicious Centaurs are pretty much worthless, so just focus on trying to find the Vengeful Centaurs They will drop 500k and probably some material too :p Trick is you gotta find em from a bunch of Vicious Centaurs lol

As a sidenote, i can be wrong but i remember loong time ago hearing that when you have ~900 defense, the centaurs hit only 1's on you o.o
