Strategy:
----------------
Phase1:

- Open with rockets and charge with blade that will help you avoid the starting missiles aimed at you 0:03
- Be aggressive and try to setup DPS not just spam 0:08
- Try to break shields with rockets/assault rifle so when the Balteus is down you have opener with dual blade (2 hits with sword) and follow up with rockets when the CD ends. 0:10
( Rockets - Break Shield - Dual attack with sword - Rockets )
- When boss is downed, try to position yourself behind it (because his back part is slightly in the air). This way you can spam all vertical missiles instantly into the boss (insane DPS).
- Every time boss shells and spams sending swarm of rockets onto you that is your go to to get that gap closer, while avoiding rockets, and do insane damage (this is good for us because boss is static when doing so meaning all of our 16 rockets will hit the shield). 0:29
-Repeat until approximately 50% of hp. 0:35

Phase2:

- Starts with the big bang (boss explodes and gets shield back).
- When you lower the boss around 40-55% you instantly turn away and run towards the other side of the room (helps if boss is NOT in the middle) more space to run.
- When he explodes and gets his shield back, he will change (add) new patters of attack. He will instantly spam missiles on you, while doing some flame sword swings. I tried dodging them, but its inconsistent because this is not Dark Souls, and we have tons of rockets staggering us.
- So to be safe, just move away and while away regen your stamina, and fly. 0:39
- Some of the rockets will go on you, but majority of boss attacks, if all will fail.
- There are still signaling missiles, but when you see 2 signaling missiles that means boss will do CRAB attack 1:41 and incinerate everything in his path. (just fly out of this attack and keep in mind he can do this mid air and kill you when it bugs).
- Goal now is to play long game poking shield with rockets while avoiding all attacks.
- When you see turtling and preparing for swarm of missiles or shield is down, keep in mind to play mid range so you can easily close the gap and start damage like insane 1:51
- It helps to enter this phase with 2 heals at least for recovery.
- Damage rotation same as Phase 1 (but keep eye on fire attacks).

PS. Lock the boss so you miss less with sword.
PSS. If you enter P2 and boss starts his flaming attack but he didn't explode and regenerate shield, don't be happy, HE WILL EXPLODE RANDOMLY so this is kinda the worst thing that can happen when changing phases. :)
