Long time xbox player. There are certain places where draugr deathlords drop ebony weapons and it its possible to get these at verylow levels. I cant tell if its mods or a pc fix but now its ancient silver weapons?

"Ancient silver weapons" do no exist in the game; they come from a mod.

What weapon mods are you using? I use Jaysus Swords, Immersive Weapons, and Chronicles of Steel- all of which add tons of weapons to the game but I still find high level draugr deathlords with ebony weapons in addition to modded weapons.

Only immersive weapons. Also using immersive creatures. At level 20 and suprised that draugr had different weapons.

Hmm I don't remember ever seeing "Ancient Silver Weapons" in my game. I've seen silver, honed silver, and refined silver though. Make sure you have Immersive Weapons loaded correctly in your load order. That might fix it so ebony weapons appear too.
