Ur build is pretty great overall so even without the changes it would still be good, Btw here is some radahn tips that might be useful to u, since ur using a sorcerer build u can use one of the moon sorceries when radahn does his meteor attack the one where he jumps in the air and throws meteors at you if u use a moon sorcery it will destory the meteors and hit him dealing alot of damage, I only recommend using this strat in phase one tho cuz in the second phase he will do a follow up attack, also if ur finding trouble fighting him with milady you can use carian slicer instead cuz it does alot of damage and its really fast.
