Actually those Thalmor Wizards are among the best available mages of any race.
When you have a corpse of such , save game and use Revenant.
If they resist , they are at least level 28.
Reload save and try Dread Zombie , if resisted then at least a 36.
Some may be too high level for Dead Thrall.
Shock and fire spells , mage armor , wards , banish daedra , turn undead , and conjure storm atronach!
Sounds perfect. Should I aim for a female to avoid the terrible moans?
Up to you.
I always thought the male moan sounded like a cave bear being raped by a horker but you might like how over the top it is
A lvl 36 male(565 hp!) is certainly worth using if only for a while
Because level and gender are rather random , you may have several thrall choices among the embassy group usually encountered.
Not an easy fight as they are supported by a more or less equal number of leveled soldiers in a relatively small area.
There are 2 wizards in the courtyard
as many as 3 more inside the cramped barracks .
Once thralled , keep with you until you are ready to move on to another minion. After a day or so outside of your cell , they typically respawn like most other enemies.
Their gloves and boots can be enchanted and any wizard will wear any other wizard`s gear
Don`t waste your time thralling randomly encountered Thalmor from patrols as they are extremely unstable and rapidly vanish
