This one is at level 81, wields a Daedric greatsword, Bow, and Arrows, has a Conjuration spell (Conjure Dremora Lord Archer), and has all perks in Two-hand, Heavy Armor, Archery, Conjuration, and Block. If you want a unbroken version of the Dremora Archer, all Dremora now carry Daedric Bows and Arrows and levels with the player at the same cost as a normal Demora summon.

All can be found in a chest by the Skyforge next to one of the archery targets.
This mod is available for Skyrim SE on all systems under the same name however, I will no longer be updating that version as I am no longer able to reach it for some unknown reason.
