Hi. This staff is rare in general, but less useful. I consider this to be of equal value to it's insc partner.
Basing it off Kamadan Chat Site, the item is worth 5-10a.
Problem can be sometimes finding a buyer for such items.
They drop every 50-200 staffs, as far as I know, making them extremely rare.

thank you for the info Montrell
