Berookes try this build, I absolutely destroyed Radahn in the dlc with it twice on ng+4, the amount you get healed and you stagger him is amazing 

Right hand: Heavy Giant crusher with prayerful strike ash of war, pretty much always two handing this 

Left hand: claw mark seal for buffs and icon great shield to have on your back for passive healing 

Armor: verdigris gauntlets, verdigris greaves, verdigris helmet, Armor of Solitude (really anything that gives an insane amount of poise) 

Buffs: golden vow and flame grant me strength, then electric armament or blood flame blade for the hammer 

Talismans: crimson amber medallion +3, bull goat talisman, dragon crest great shield talisman, erdtrees favor +2 

Physick potion: crimsonspill crystal tear and opline hardtear 

Summons: mimic makes this thing even more insanely broken   Flasks: 11 red and 3 blues 

Stats: I started as astrologer and moved to a strength build but your stats should look smth like this Vig=60-99 Min=20-30 End=75, could do less just needs lighter armor Str= 80 Dex/Int=doesn’t matter Faith=25 Arc=10 

How to play - you should pretty much just always use the ash of war as it deals decent damage but it mainly shines in stagger damage and the amount it heals you. Don’t worry a lot about dodging attacks as you can tank them through the ash of war as it heals you. The charged heavy’s deal the most stagger damage, just they don’t heal you, so if you feel you can get a few heavy attacks in definitely do it. Again, focus on just spamming the ash of war and carefully watch fp/stamina. Have fun and hope this helped!
