information and item lists.
I need help with Phar dar earring quest, I have everything but npc in Tactics will not give me "a vial of blck blood"
Any ideas?

i possibly remember mention of needing flags from killing Vallon and Tallon Zek before you can get the blood.

Yes, you need TZ/VZ flags to get the black blood, however the pulsing black vial is droppable, so a friend with the flags can do that part for you.

You can usually find them for sale in the bazaar now as many people don't do the quest anymore and some people have a few leftover from when they were selling for 20k+
