I've been looking for easy ways to farm blood of sargeras with minimal effort in the forums, and I haven't found any. I've been always the AH type and farming Blood of Sargeras to craft stupid rare gems really got in my way. So I'll share what I'm doing nowadays to get them with low effort.

This is intended for your crafting alts, the ones that need the Blood of Sargeras (In my case, three jewelcrafting alts)This is RNG heavy, but has been working for me just fine in the last weekRequisites

Revered with The Wardens, as you need the Bloodhunter enchant in your shouldersPark the char in a area with high mob density (the murloc island in Val'Sharah, or any raptor WQ place)Explanation My aim is to take advantage of the "bad luck protection" that Blizz has implemented in the game, and log in with the chars, get a quick drop for Bloodhunter's Quarry, worth 1-5 Blood of Sargeras, log out, be back later.

So I've been logging every ~2 hours, and it's really easy to get your Bloodhunter's Quarry drop by pulling packs of 10+ mobs and slaughtering them, usually doesn't take more than 4-5 pulls of this kind to get it. I tried to log in every hour, but either I've been RNG screwed or this "bad luck protection" has more than 60mins CD
