according to blizzard:
[blizzard]To clarify, all epic-quality items in a raid dungeon that can be disenchanted will produce Blood Spirits.[/blizzard]
They also drop off bosses, mainly from cache's and not bosses themselves. So the chests left after defeating them and it is a VERY low drop rate.
As of right now, they cannot be bought with points of any kind from any vendor.
I saw 2 on the AH last night for 2500g a piece.
Yea they aren't BoP so you can find them on the AH and im betting the Black Market AH also.
Also this thread is now unlocked. I must have checked that box accidentally in my half asleep haze when posting, heh.
