Underlight Angler



Underlight Angler is an artifact fishing pole. Crafted by Marcia Chase, the rod is made from the head lure of the deep sea murloc Mglrrp, which apparently gives the rod its power, and the body of the rod is made from Mglrrp's skeleton.

Unlike the other Legion artifacts, the Underlight Angler's power was not sacrificed to draw out the darkness from the Sword of Sargeras to stabilize Azeroth's wounds, and thus it is usable in Battle for Azeroth and beyond.
