Upgrading the quality of your low level Rb-ed items

Okay let say I am reborning my elite socket items such as my earrnings. necklace, ring and boots. How many DBs does it require for each to upgrade its quality to super?

I think 5 in market and as little as 1 in TC.

lol 1 to infinity in Tc..lol get lucky time...

Depend on ur luck. 1-5 at least on each on.
