Cazza Fable - "From North" brings up a great point: do some daedric shrine questing.
I beleive there are several enchanted longswords ... found a few ... not the Daedric Crescent
You can find the artifact book in the Mournhold Museum ... there is a link in this forum which notes all the artifacts + their locations ... sorry I can't help here, because I prefer to stumble upon them
To get some excellent longswords make "runs" through every Daedric Shrine.
I believe the good weapons start showing up once you hit Level 15.
The best is the Daderic dai-katana ... well, at least it's value is $120,000 (?)
You can clean it out ... I believe about 4 enemies per visit
Go do something and come back = 4 different enemies etc
There are 2 Daedric shrines over by Hla Oad .. I call it the race track
Way out there in the water.
Hit one; then the other ... reverse course and just keep fighting till you find a weapon you like
Good way to trap Golden Saints as well ... believe they appear around level 15 as well
The Dremora Lords seem to pop up around level 17(?)
Another good hunting spot is Indorayon ... NW of Sadith Mora
Easy pickings if you have a ranged attack ... Bow or Spells
You can make runs in front door; out the back = repeat
You can also hit the Hlaalu and Telvanni vaults.
Just did them ... found a Daedric Claymore and a Daedric Dai-Katana ... several Daedric Katana's
Have you started the Nevarine Prophecy quests ?
The Urshilaku(sp?) Camp/Sul-Mutul/Bonebiter Bow quest offers several nice goodies ... glass longsword with some damage enhancement + a Dreugh Cuirass
Search well
***** SPOILERS *****
Indorayon - the nut job is the master enchanter
You need to calm humanoid him if you want to get your enchanting skill to 100.
The experts have clever ways to up Enchanting ... Dragon Wench had a excellent way in a older post = it was a bit over my head = she's smart; I'm not
As for you basic enchantable weapons(... buy Grand Soul gems in Mournhold OR they seem to pop up around level 20 in fights/caverns etc) you can easily rob the Redoran treasury/vault.
After your post I did a few runs at it ... found a Daedric Longsword ... Ebony Longsword ... Ebony Broadsword
The experts can verify or correct me, but I believe you can change the vault contents if you don't like what you find = just get caught stealing and reload the prior save ?
I found different weapons each time.
To get the quest talk to the Kahjit in the Pelagiad Tavern ... one of several quests to be her "very special friend".
If you don't want to do the other quests, the key is upstairs in the Dralor mansion(?) ... have to steal it
If you have problems stealing it, I can give you some tips on stealing the key + looting the vault.
As for your Medium Armor.
I found the body ... NE of Maar Gan ... levitate to the stronghold Kogoruhn and you'll see a body on the roof ... the note of caution is; you cant wear the helmet/cuirass in the presence of other Ordinators ... they will attack you
You can also steal Indoril armor placed within Ghostgate.
I think someone sells pieces ... sorry I can't be more clear = just going off memory from my last play
Glass armor has a higher rating and is much lighter (?) ... but it's light armor = you can sell it
It can be stolen from Ghostgate.
You just need the Ring of Surroundings + Amulet of Shadows ... I think I had a Sneak of 35
If you want to go the Light Armor route ?
Sorry, I could not black out the text ... tried the wrap spoiler tags option
So, I just put SPOLIER in my post.
