Before you try refining know that:
Max refine is +20 states, either mc,sc or dc.
Items that drop has various different mc,sc,dc depending on the scroll and char used to open it. so if a weap is +5 dc then you can only refine up to 15 states max
you can use pure orb to make the weap +12 then you can only refine it up to 8 times to reach maximum states of +20.. bare in mind the weapon wont break if you use Orbs
Currently there is no use and it is a waste of time refining unless GM makes refining to go as far as say +50 states
Also saying that its far better and cheaper to design a weapon using weapon designs and essences.. results are far more appealing and less risky
