You are required to fish up 1x Severed Arm to complete this quest. The Severed Arm can only be found within a Bloated Monsterbelly. A Bloated Monsterbelly can only be caught fishing in a Deep Sea Monsterbelly School, which can only be found in the Southwestern Frozen Sea. There are a bunch of icebergs located at (81, 57) in The Frozen Sea, just South of Death’s Stand (84, 43) in the Borean Tundra. Once you have caught your Bloated Monsterbelly, you can open it and loot the Severed Arm.
You must then return the Severed Arm to Olisarra the Kind located at inside the “First to Your Aid” shop (53, 64) in Northwestern Dalaran. Olisarra will then reward you with: 1x Bag of Fishing Treasures, 250 Kirin Tor Rep.
