I did not try to exploit anything I just used three of my skills to effectively upgrade my weapons. I have 5/5 into the perk for one handed that right there is +100% damage for one-handed weapons. I put one-handed weapon enchant on my boots/ring/neck/gloves for +48% one-handed weapon damage each that's another +192%. Then when I forged and upgraded my weapons I used a chest/ring/neck/gloves that had upgrade armor and weapon enchants on them as well as a potions that increased weapon and armor upgrade effectiveness. I just effectively used what alchemy/enchanting/blacksmithing are supposed to be used for. When I started off in crafting them did I expect them to be that powerful? No, I did not, but I am not going to be like "oh I cant use anything in the game because it will make me too powerful."
So you massively overpowered your stuff on purpose and knew what you were doing, then complain you're too strong?
I have a 124 damage mace with full smithing, smithing potions, perks in one handed, and one handed boosting ring and necklace. Yet it still takes a ton of hits on Expert for a Draugr DeathLord
So it's very easy not to overpower yourself. I actually tried to overpower myself, and couldn't.
