Band of Impenetrable Defenses
this dropped for a guildie and alla says to price it at 1k. it is comparable to the ring from shade, minus about 200 armor. imo, it is worth exactly 36 stam and 22 defense... so that comes out to three 12 stam gems (50g each on my server), and 3 vindicator's armor kits (24 defense), put a little bit on top for the epic brand name and that's the price i would pay for it. there are several blue tanking rings with maybe 10ish less stam but more avoidance/defense/block value on them.
opinions are welcome.
