Find upgrades, do more damage, win.
Pawn helps you find upgrades for your gear and tell which of two items is better for your spec. Start with built-in advice from Ask Mr. Robot, or customize Pawn's stat weights to have it suggest items based on your favorite class guide or simulator. Pawn can help you decide whether it's better to use the cloak with 100 mastery or the one with 80 crit—whether you're just starting out, or you're an advanced player who plans out gear upgrades and regularly simulates and evaluates performance.
If you're new to Pawn, don't worry—Pawn will automatically set itself up to give you advice based on math done by the experts at Ask Mr. Robot (or, on Classic versions, HawsJon). Just watch for Pawn's green arrows. If you decide you want to go further, there are a lot of ways that you can customize Pawn, by tracking multiple specs at once, importing custom stat weights, and more.

Found a bug?
If something doesn't seem to be working right, just leave a comment here. In addition to a description of the problem, please make sure to include: (1) the language that you play WoW in, (2) whether it's Shadowlands, Classic Era, Burning Crusade Classic, or Wrath of the Lich King Classic, (3) the specific items that don't work as expected, and (4) your class and spec if you're using the built-in (not custom) stat weights. Screenshots are usually very helpful, and typically the most helpful thing you can provide is a full item ID (12345:67:89:0, etc.). You can find the full ID for an item by turning on Pawn's "show item IDs" feature or by putting it into Pawn's Compare tab and Alt+LeftClicking it and then copying it from the box that appears. (You can also get the first number from the item ID from any Wowhead item link, and that's usually enough, but not for items with enchantments or upgrades or random stats.)
Where are the green arrows in my bags?!
Blizzard removed the code for this feature entirely in 10.0.2. I'm as confused as you are. For now, you can still get them back if you update to the latest version of Pawn and your favorite bag addon; it just won't work with the game's built-in bags.
