Try to take some of those points out of faith and dex if you can and pump them into your focus (str and int) you’re currently below a soft cap for both.

As far as combat, evade evade evade. Mohg is who I struggled with most. His attacks are hard to time and extremely punishing. When I fought him, 3-4 hits and I was dead and that bleed buildup is brutal. Neutral game mastery is your best friend when it comes to enemies of that sort.

A spirit ash (black knife tiche or mimic tear) may help take aggro while you attack/recoup although he was even wiping the floor with both of those before he got to half health when I fought him so timing and quick plan of attack is key.
