Fresh Blood is used to pop a new NM in Dnagruf Wadi. Its a leech named Chocoboleech. Its located in the F-9 and E-10 area as a ???, but you have to look for it since the ??? moves like the one at the Crags to pop the Goblin Archaeologist. Trade the blood to the ??? and he'll pop. Not very strong, I killed him with my DRK lvl 54, did a total of 4 dmg to me; BUT once he pops any leech nearby will link so a low lvl might get mobbed if not careful. He drops a Katana called Gassan.
just got a Vial of Fresh Blood off a sheep (was making Galkan Sausages... sheep got in the way). Is this a new item from the July 19th update? I presume it's either for a quest or for a new synthing recipe? does anyone know anything?
In South Gustaberg, there's a path that leads up to a goblin camp and a couple sheep for the Smoke on the Mountain quest. The path can be found in the northeast corner of K-10. There's also a good number of them on Vomp Hill.
In North Gustaberg, they're all along the path to the top of Zegham Hill. There's a path that starts near the center of I-6. If you decide to head up there, you may as well do the Hearts of Mythril quest, too.
