IF you want to play this build at SL 120 then you can drop str and dex to 20 and faith to 30; though you will need to exchange the darkmoon talisman for the canvas talisman if you want the maximum amount of damage. This build is meant to be an NG+ character since it is impossible (as far as I know) to obtain both sunlight blade and the darkmoon talisman. I would recommend getting the miracle in the first playthrough then getting the talisman in the second when your faith is high enough to make the darkmoon talisman stronger than the canvas talisman. Also, if you want to use a weapon that has better scaling then you can change the levels around. The uchigatana has better damage even when both str and dex are capped and you could take the 26 levels from strength and put it into either vitality to have more survivability or you can but 10 points into faith and dex and 6 into attunement and put on soothing sunlight/bountiful sunlight(if you want to be in the Princess guard) and one other miracle or spell that takes a single slot. Enjoy playing the build!
