1 db for upgrading quality

First u need the item u want to upgrade and spam on him just 1 met and if the item go for next lvl up spam a DB and u ll upgrade the item(but if u dont get a upgraded with 1 met dont use any DB u ll need to much in that case this works with 1 met upgraded. i use this when i make superclubs 2 sockets or other weapons.
P.S(sorry for the bad english)

k? so you mean if you want a super you use a met first to upgrade it and then a db???

yea if the item get up upgraded with 1 met it is 99% sure u ll upgrade it with 1 db.
