Sorry I have looked for 3 days stright and can not find bloodworm helm or umbra npc anywhere any help would be greatly appreaciated love the mod its has everything I like about mods great mod but if I can not find the last two items I will have to uninstall because I can complete quest. If you would like to email me instead of posting anything here my email is firstname.lastname@example.org Please help I really love this mod. Thank you.
Umbra is generally hanging around behind Soljunds sinkhole (a mine) in the Reach its just to the east of a couple of camps.
I seem to remember Bloodworm helm was on a vampire necromancer in Potemas sanctum under Solitude but you need to trigger the Wolf Queen awakened side quest (which it self requires the man who cried wolf quest).
In case you don't find them I will look up the stage numbers for the quests so you can kill the quest from the console - uninstall would be a bit extreme!
Icecreamassasin has not indicated so this time, although he has said in the past you may want to empty the safe to be on the safe side. I have upgraded to 9.7 without doing this and everything is still in the right place; depends how paranoid you are! I will email you console commands in case you need them.
