Upgrade 11 DG EGYB

[nsns2304]

Hi guys, i just got a 11 dg Egy B Shield and wanted to upgrade it. But i always fail at +6. I just burned 4 Immortal stones. Is it normal? or do i have to take care of sth?

It's normal. Try get Lucky avatar and Premium (U can create new char to get premium).

even though joymax added the 10% luck, it's still difficult to ++ items.
you need the following (to increase probability):

 Spoiler

(a) lucky stone
(b) lucky dress (tradeable)
(c) premium + (create a new char, then you should have it)
(d) lucky powder
(e) steady stone [optional] (to prevent durability reduction)

same as Svesik written above.
