Hello everyone!

I've been wondering... Does anyone know where to find the Thavnairian Leather and Thavnairian Silk for the dancer outfit? I've been searching all over the place for information on the matter but nobody seem to know exactly where to find it.

As for as I know, they are not from Ventures or at least not lvl 60 ventures. I believe to be part of maps but which one and how rare it is? I've done 4 lvl 60 maps so far and nothing seems to drop so far yet someone on Behemoth managed to find one somewhere.

Anyone know where to find it?
