Guild Wars 2

I need powerful venom sacs, vials of powerful blood and ancient bones. Where is a good place to get these ingredients? So far, I have had 0 luck, outside the 3/5/8 I found while leveling to 80.

I get Ancient Bones in Orr killing Risen. They rarely drop from them, but you definitely see a form of consistency with it. I heard vials of powerful blood have a good chance to drop from trolls in Frostgorge Sound.

I’ve only gotten Powerful Venom Sacs from bags dropped by the Risen in Orr.
