Nid some info on skills enchantment's codex book. I have used the normal Giant's Codex book (bought from Giant SubangJaya) to enchant my Hammer Crush skill to +11 Chance. Now I lost something round between my legs but still wanna continue to + it without bursting.

Question : Can i use Mastery Codex to continue enchanting from +11 upwards? Or must i start back at +1?

Thanks in advance to the LYT guru's infos.
