Shigossa Metal Stone

I'm considering crafting 60 lvl purple blacksmith items. But i cannot find "Shigassa Metal Stone" on AH. It drops form DoD Bosses (as Ive read on rom forum). Is it bounded? How much do you sold it on AH?

Sry for my English.

Unfortunately i never met such a thing during my DoD experience, Kiku. But as i had heared, crafting items those r farmed at DoD bosses may reach very high (a few millions) prices >.<
I suppose that shigassa is not bound, but extremely rare drop, and theoritically may appear in AH. THough im nor really sure about that.

English is not bad at all btw

I know that there must be sth tricky. Cheap materials (required for 1 item: 418 ore1+ore2+wood1), free chest recipes (I was shocked but its really free - 0 gold), main recips for 20 mementos and finally shigossa metal stone.
Hmmm, so I must look on AH and check the price.

As I checked on AH it's for 1,000,000 gold.

Not a little price at all >.< although drop is really rare one it seems! Well, if i'll get such a drop accidentally, u may hope on the good discount
