weird that this happened, just wanted to mention it to see if anyone else had this happen. I just applied patch 1.4 last night, played last night for about 4 hours with no problems at all, fixed all the lag i was having and let me give up those damn bard's instruments i was dumb enough to loot before getting the quest (hingsight is 20/20). Today I started playing again and had no problems, started clearing out Shroud Hearth Barrow in Ivarstead, finished that then when and trained Conjuration with Falion from level 70 to level 80 and then went to the College to buy some new spells from the Conjuration dude. Bought all the new ones, including Conjure Dremora Lord + Storm Atronach, Expel Daedra, Command Daedra, and Dread Zombie. Messed around with them, then as a test, i saved and then conjured the Dremora Lord and then unlocked the conjuration perks to dual cast, cast farther away, double duration time for atronach's and then atronach's are more powerful perks. Tested after each one to see exactly how much longer the Dremora would last, and after dual casting with the double duration perk, he lasted 4:25-4:30. real time. pretty good, then i tried with the Sanguine Staff and noticed that conjure's a Dremora Valynaz (which brings up another question, the guidebook says under daedra that there is the Dremora, Dremora Lord and others and the most powerful being the Dremora Valkynaz, with a "K", but the staff conjures a Valynaz, so who made the typo? Bethesda programmer's or Prima Guides? Wouldn't be Bethesda's first typo that's for sure, "Blessing of Talos: Reduces Time Between Shouts By 0%"??? lol, but its really 20%). Anyways, I digress, so I realized the staff makes a Master Dremora basically, cool right? Then I fast travel to Ivarstead again, and go to the Island to do the Forbidden Legend Quest. When I get inside I use the staff and everything's normal except no conjuration. Nothing happens, the charge is decreased and everything but no dude. I can use my spell, but not my staff anymore! I have tried selling it and buying it back, waiting, even dropping it and having a follower pick it up and use it to no avail. In the end I rolled back to before clearing out Shroud Hearth Barrow unfortunately, bummer. Sorry for the length but I like to make all the details and fact's known. Btw, I am level 70 with 250 hours of gameplay, save size: 11mb. Thanks, Ragnar-the-Red.

It's a glitch. Conjuration Staves that summons Daedra wont work after a certain perk BUT your follower will still use it while you can use the Dremora Lord Spell.

so your saying that one of the perks I chose was the cause? That If i roll back and do it all over it will result the same way? One of the perks I took prevents the staff summons from working for me but not a follower, but yet I can still use the spells to summon every other type of conjuration in the game? Thank you for your help, it has been HUGE. Now I know to save, take the perk, test it and save, take a perk, test it and save again until i find the little bugger thats causing this! Thank you Jusey1 !

theres a mod to fix this this issue

Aye. Elemental Potency would be the issue there. I didn't see the bug listed in UESP's article on Conjuration, but if you look at the item page for Sanguine Rose, it lists this problem under "Bugs".

Eh.. Do what I do and give the Rose to your follower then buy the Summon Dremora Lord Spell and get the Twin Soul Perk..

2 Dremora Lords + 1 Dremora Valkynaz + 2 Lizards in Daedric Armor.... Maybe 1 Lizard.. I don't need to fight half the time XD

sounds like a good plan, thanks for all your help yall!

@Jusey1: what do you mean Lizards? Are you saying your an Argonian character with an Argonian follower? Where do you get an Argonian follower!? I want one! Thanks essay!

I'm an Argonian and Derkeethus is the Argonian Follower. Save him from Darkwater Pass. Fine the Darkwater mine then the cave he is in should be nearby. He is the only follower that's a quest-person. It's the Riverfall that is like East from Ivarstood.

cool, thanks man!
