No other weapon, bar some tomes and I think some of the fan daggers have 120% + scaling. The base sword, which can be rebelled comes close to this sword's stat scaling (110% STR iirc), but it falls short due to not being a casting weapon.

Hell, most weapons that you can craft from the books you can buy begin to drop rapidly in scaling the second you add any sort of effect or stars to them.
