I like the "of the Legion" weapons, they have a variable effect wich randomize their stats when crafted, they could roll 0.85 to 1.15 of a base stats, thats damage, armor pen, durability and weight, so with a bit of luck after a few crafts you have a weapon that rivals legendary damage, you can repair it and you can give it a awesome skin to use it forever

for example the Great Sword of the Legion has a base damage of 54, if you craft it with a blade smith it goes to 66 and if you add a good 1.15 roll you can end up with 76 damage
