Master the Umi-Bozu boss fight in Nioh 3's Part 27! Learn its two phases, weak points, and strategies to overcome its powerful attacks and emerge victorious.

Alright, let's talk about Part 27! We're about to face off against a giant, flan-like monster called Umi-Bozu. Don't worry, this fight is totally manageable once you know what you're doing. The biggest thing to remember is that Umi-Bozu is super weak to FIRE. Seriously, lean into that! If you lit all those bonfires before this fight, you're in luck – you can even light your weapon on fire during the battle, and those bonfires will also take out any pesky Flan enemies that try to join the party. Also, those Fire Amulets I recommended earlier? Now's the perfect time to use them!

This fight has two main parts. First, Umi-Bozu is huge and out in the water, mostly shooting blobs at you and slamming its tentacles. It has a nasty 'Light Beam' attack that can one-shot you, so definitely avoid that at all costs. Once you survive that, he'll move to the dock with you for phase two.

When you reach the dock, Umi-Bozu will spawn two Flan enemies. Your first priority is to get fire on your weapon and use 'Rejuvenate' if you have it. Take out those two Flans quickly – he won't summon more, so it's worth the effort. After that, focus on Umi-Bozu. His 'Slam' move is a good opportunity: dash to the side twice to dodge it, and his squishy core will be exposed for you to wail on. Extra points if your weapon is still on fire!

Let's break down his moves so you know exactly what to expect:

  1. Tentacle Slam: Umi-Bozu will form an arm-like shape and slam it down. Just dodge to the side when you see it coming. If you can get in front of his body, you'll usually be safe and can attack his body or arms.
  2. Water Shot: This is more annoying than dangerous. He'll shoot blobs of water that do minor damage and can inflict the 'Water' status, which lowers your physical defense. They also leave Yokai Realm patches on the ground. Guard if you can't dodge.
  3. Flop Attack: This happens after you've broken off his body parts. He'll rear up and flop down to try and squish you. He aims pretty well if you're in front, so try to get behind him or keep your distance. If you have enough Ki, you can even block it and keep attacking.
  4. Light Beam: This is the big one. Watch his eyes move to his mouth – that's your cue to get out of the way FAST. He'll unleash a beam of light that does over 2000 damage and will almost certainly kill you unless you're massively over-leveled. Dodge, but be quick!
  5. Tentacle Sweep: This is a second-phase move once he's on the dock. He'll sweep his tentacles across the dock when you're nearby. It's pretty fast, so guarding is a good option here.
  6. Jump Attack: Another second-phase move. Umi-Bozu jumps up and lands, trying to hit you. His body tends to splay out a bit on landing, which can still hurt you.

Read through these, and then go show this giant flan creature who's boss!
