Ozma: 3-Phase Final Boss Fight & True Ending | Dual-Wield / No Damage | The First Berserker: Khazan

Solo Ozma boss fight on Normal difficulty using the Dual Wield (Warrior set) with heavy armour (Great General set) at the recommended level of 134.
No commentary & No damage taken, truth ending with all three phases.

This video is not about whomping the boss - that's easy. This is intended as a guide to show what he is capable of and how to beat him no matter what BS he throws at you. Only 4 of his 50+ attacks are missing here.

I uploaded this already but after days of trying I knew I could do better and show a lot more so I redid the fight. This time I turned off cutscene replay and edited the cutscenes back in after.

I wanted to make a point of using a normal build. I could have respecced for no-hit but left my character as I first encountered the boss to keep everything as fair as possible. Even with this build if I laid into him I could have done this in less than half the time, he can be stun-locked and a lot of his attacks can be interrupted. When you learn the 50+ attacks he is not that difficult...

Seriously good boss design and 3 really punishing fights which took me a while to figure out.
I was massively holding back here to let him show off as many attacks as possible but even still there are 4 attacks he didn't get to use:
Phase 2 unblockable wing stab - same timing as the grab attack
Phase 2 volley of tiny projectiles [easy late dodge]
phase 2 sequence of chaos projectiles [extremely easy to dodge] and
the only new attack he gets in phase 3 apart from variations: the total BS teleport-suckerpunch followup attack which caught most of my runs. He usually does that after the gravity blast. Just keep distance during teleports to avoid, but damage from this is very low.

Every attack he has can be dodged or blocked - even each tick of the waterfowl dance attack he does in phase2/3 can be brink blocked (but not worth the risk), likewise the timing for brink dodging some of the spells is crazy tight and the chaos buildup isn't worth it - dodge the spells, block everything else.

I started with the spear and later on tried different weapons. There's a lot of complaining about how OP the spear is, but IMO all 3 weapons are equally viable and can become just as devastating when built into. Moonlight Stance just makes the spear the simplest to accidentally be good with. Dual-wield was the hardest for me to master but for level exploration especially it's extremely powerful.

*this was completed on the May patch, but is uploaded after the June patch. Updates with this game have affected performance and so I have been playing offline. There's no advantage gained in the patch played on, and the new difficulty modes don't make a difference for what I'm doing here - if anything the new highest difficulty would make this easier because the hardest part is keeping him alive long enough to use all of his attacks.

My main gripe with the game is the inability to overwrite the deadzone on the sticks which makes camera movement choppy. Frankly performance got to me a few times too, but that's the Unreal Engine for you - all hype no stability.
