This fight is much easier when you have enough room to move and a loadout you understand. Preparation should simplify the encounter instead of adding several unfamiliar systems at once.
Create enough movement space
Clear horizontal space so movement is not blocked by terrain while you are learning the attack pattern.
Use the best movement tools you already have
Reliable movement often matters more than a small damage increase.
Bring practical recovery
Keep healing and other consumables easy to access before the fight starts.
Use early attempts to learn the pattern
If the fight fails, change one weak point at a time rather than rebuilding everything.
