Just started doing my Son's of Hodir quests and came upon the quest ...
You get the quest item to use on dead giant bodies to the east. The goal of this quest is to retrieve . Each time you mine one of the giants, he will either spawn 3 enemies with 5k health, or give you a quest item.
Now here's the good part, even when you get the 8 Stormforged Eyes, you can still mine the giants and get the easy to kill guys with 5k health. These 3 ambushers have chances to drop Relic's of Ulduar, Frostweave Cloth, and random greens.
So basically, clean out your bags, pick up the quest and mine the giants for a few hours. When you're done, just don't turn the quest on and come back to farm later.
