Need help to take this black flame dex/faith build to lvl 150, with DLC weapons

Hey everyone,

I’ve finally unlocked DLC and want to spec/ modify my black flame dex/faith build to include DLC weapons and anything else to make it high rank. I’ve also been pumping points into vigor as I’m unsure if I should lvl dex faith or str anymore

Currently use maxed out keen grave scythe, maxed out halo scythe and gods layer great sword

Any advice would be massively appreciated! This is my first build so it mightn’t look super optimal.
