How do you summon dremora lord in skyrim?

pm me.

Conjuration spell. You need a high level conjuration to be able to see it in shops.

which shops?

put a normal spell book in the barel whit ure money and change the hex code for 0010FD60

Try checking the Winterhold college vendors.

You need like 80+ conjuration I think.

I thought it was 100.

It is 100 and you have to go talk to the conjuration master
