Great Build for beating Dancer before Vordt: Warrior with Life Ring burial gift. Silver Serpent Ring and Blue Tearstone Ring. Get the Deep Battle Axe from the Mimic. Silver Eagle Kite Shield for 100 physical block and Weapon Skill. Collect every titanite Shard, including the ones from both Pus of Man. Farm Lothric Knights if needed. Upgrade Deep Battle Axe to +2 Level Vitality and Endurance. At SL 23, I had 23 Vit and 19 End, which gets you close to 1000HP before Embering. Embering can be used as a final Estus if your attempt is going well. Embers are limited at this point in the game, so I would practice going without them until you're having a good run.
