Quest lines wrap up & Dancer
Before fighting the next boss, spend some time to wrap up all loose ends at Irithyll Dungeon. You need to grab some items and rescue an NPC. Refer to the next video.

Next, wrap up Sirris' questline so she would co-op with you during the fights against two end-game bosses. You will be summoned into Sirris' world to help her defeat Hodrick. Beware: the fight is tough because Hodrick hits hard. Here's an effective strategy. Infuse a Rotten Ghru Spear with a Poison Gem and upgrade the weapon to at least +6. You might need to farm the Ghrus in front of the Abyss Watcher's arena. The Rotten Ghru Spear will also be used against a boss in one of the DLCs, so it's worth your time to farm the weapon. Infuse the Bandit's Knife with a Blood Gem and upgrade the weapon to at least +6. Start the fight by using the Poison Rotten Ghru Spear to poison Hodrick. Once he is poisoned, use the Blood Bandit's Knife to bleed him.

Dancer of the Boreal Valley
24. Dancer of the Boreal Valley, Dark Souls III
Dancer is another gatekeeper boss. You must defeat her in order to access the end-game bosses and finish the game. Her attacks can be difficult to dodge, meaning that you should use a shield whenever you're not comfortable dodging an attack. Use a shield that has high physical and fire defense, but also keeps your weight ratio below 70%. The Dragon Crest Shield is recommended; upgrade this shield to at least +4. Stack as much physical and fire defense as possible. Consume a Red Bug Pellet and buff your Raw Broadsword with Gold Pine Resin/Bundle.
