Yeah, it's Thor'idal. Delete Thori'dal from your itemcache, then do a mass wowhead update.

For bears, it seems that Elixir of Protection (Mixology) is counted as "Armor" and not "Bonus Armor"

Thanks, will fix that.

Looks like at least [Keystone Great-Ring] and [Defender's Code] are still not properly being marked unique, even after a wowhead update on the item.

I downloaded 2.1.6 last night and configured all of my tankadin gear, but [Libram of Obstruction] wasn't on the list, and any attempt to choose librams seemed to crash Rawr for me. Everything else was smooth and the new blacksmithing socket interface is very nice.

Librams are definitely incomplete, but I don't know of any crashing related to that. What did you do to make it crash, and what was the crash log?

Deleted Thori'dal, still have the issue. It's barfing in the low numbers of parses (91st and 340th or so, not a consistent number). To complicate matters, if I then try and update any other item from Wowhead before exiting and reloading Rawr, the same error pops up, but this time the item no longer shows up in my item list. This persists through a reload (corrupted the entry in the cache?).

[Embrace of the Spider] appears to have incorrect values in the default item cache (has both the average haste rating and the haste rating proc, and maybe the spellpower too?). It appears correct after reloading from Armory or Wowhead.

In my rawr there are 2 different [Belt of Potent Chanting] and with different value although they seem to have the same stats.

Are you using an old version (older than the most recent one posted)?

Before he added blacksmith extra socket handling the extra gem on glove/bracer/belt was put into a new copy of the item as a 2nd (or only) gem in one of the normal gem slots.

So you'd have two of the same item (that looked like they had the same gem) showing in the list when you hover over them, but one would have unnaturally high value. In fact, if you didn't know about this, items you were currently wearing that you had downloaded when you refreshed your character against the armory would be ranked too high, and you wouldn't realize that another few items were really higher value than it.

Would it be possible to include Bonus Armor in the Relative Stat Values chart or can I just divide the value of normal armor by the appropriate amount to get the right number? If so, what would the calculation below be correct?

3/3 Thick Hide (+10%), 3/3 Survival of the Fittest (+66%) and Dire Bear Form (+370%)
-> Bonus Armor Value = Armor Value / 5,46
