Once a player has upgraded their garrison mine to level 2, it contains an often-overlooked pool of water. We think it would be fair to say fishing isn't the most popular of activities in World of Warcraft, and for those who do fish, the fishing shack holds far more allure than a glorified puddle in a cave. However, that puddle yields something of interest to fans of ye olde Savory Deviate Delight: Blind Palefish.
Blind Palefish transform you into a pale orc for 5 minutes. While you can't mount in that form, it does persist through combat, making pale orc raids on Highmaul totally viable. Unfortunately, Blind Palefish are soulbound and Unique (5), limiting how many you can carry around. You don't need maxed (or even high) fishing skill to catch them, but they have roughly a 10% catch rate -- you'll end up somewhere in the vicinity of 50 Crescent Saberfish of varying sizes before you get your 5 Palefish. If you're hoping to fish up anything other than Palefish or Saberfish, you're out of luck; nothing else can be caught in the mine.
