You MUST use them up before DEC 31st 2012, because they will cease to exist. Aka will be removed from your account.
What did you use them on?
+ If you used on Nex or Corp beast, what DROP did you get?
I still have 4 of them.
1x will be Jad (fire cape)
1x will be Queen Black Dragon
Then I don't know what else to use on.
Maybe another fire cape, and perhaps try Kiln, and use on one of the 2 Jads near the end.
EDIT: USed one and got Dragon Visage
