This build was optimised for RL1 under flawless play conditions. There are still some things that can be improved even at that, but Elden Ring Items you should take a different approach on leveled characters.
1. Use Occult infused Scavenger's Curved Swords. They're just better with Arcane scaling, especially with Seppuku. They're also lighter. Unfortunately you cannot get two of these on your own before NG+. If you do insist on running Bandit's Blood Curved Swords, aim for 50 dex, 45 arcane. If you are overleveling, get strength afterwards.
2. Use Golden Vow instead of Commander's Standard, it's a weaker buff but lasts 45 seconds instead of 30. Take into account that you spend about 20 seconds buffing after using it, that means you get 25s of buff instead of 10s. This can also be put on a light weapon like a dagger, letting you wear some armor or use Blue Dancer Charm without hardswapping.
