Howd you get its damage so high?
I'm level 56, so I needed a weapon that could keep up with my enemies, so I sadly used the alchemy, enchanting synergy loop. I had four equippable items with a +25% armor and weapon improving enchantment, and a potion that gives me a +120% armor and weapon improving effect. On top of that I have 100 one-handed. It all stacks together into a very powerful yet not godly weapon. I've seen Skyforge Steel swords that deal 600+ damage unenchanted.
Depends on character
Sword & Shield Warrior - Elven Sword and Spellbreaker... Laziness keeps me from upgrading my weapon, lol.
Daedric Artifact Hunter - Ebony Blade. The drain life effect lets me just swing away at multiple enemies and come out on top.
Pure Mage - My fists... clenching the Conjure Dremora Lord and Thunderbolt spells.
Fixed, welcome to the Elder Scrolls.
