Hi there!
Chainlink Belt of ill omens seems to have the wrong stats on AMR right now.
It shows critical strike and versatility, but in-game it is haste and mastery.
Yeah a few items got the wrong stats in our scan yesterday… wowdb just has the wrong stats for a lot of items, not sure why – we’re updating it sometime today.
Afaik Blizzard changed the stats on several items really late before release - for whatever reason. If database sites did not rescan the new items they still may have the previous versions of those items. 
Yeah the weird thing is that they had the correct stats a week or two ago…
Huh, okay - that is weird indeed…
