Try Reforging it to Legendary which will give you about +16% damage along with a few other useful stats, reforge all your Accessories to menacing which will give you +20% damage, keep your Warrior Emblem which gives you +15, and wear full Molten Armor which gives you +17% damage.

So that would be +68% extra damage, which should make your Night's Edge do more or less 71+ damage.

Hope this helps! :D
