Upgrading Items Level?

hey guys im totally new in Cabal and im level 100 but how can i upgrade my items level all my items are "Titanium" i used Upgrade Core to my Sword but its just giving+s i seen Warriors have items like "Shadow Titanium,Osmium,Red Osmium" and so on..anyone?

Shadow Titanium, Red Osmium and things are other armors.
It starts with, training, etc., bluestin, titanium,shadow-titanium, osmium, redosmium, mithril.

You need upgrade cores to upgrade your equip.

shadowsteel/aramid and lower need an upgrade core low.
titanium and lower need an upgrade core medium.
redosmium and lower need an upgrade core high.
mithril and lower need an upgrade core highest.

He was talking about the difference between Red Osmium and Osmium, as i understand. anyway, thank the one answer you were looking for ;)

I see, I got it wrong :s

You forgot SIG Metal :P

Yeah, forgot that one, but SIG Metal doesn't have a "upgraded" status, like Osmium and RED Osmium. ;D

thanks im totally newbie in Cabal i rush into that level but it seems i still need to know more about cabal^^

It's ok, just make sure you read some guides if you're in an impasse. :D
