After a few frustrating attempts where I took heavy damage and purposely reset, I finally nailed my dodges, used mid-air immobilize, and pushed the White Clad Noble into his snake form with plenty of health.
But despite dodging his attacks perfectly in phase two, he still overwhelmed and defeated me.
Back at the shrine yet again, I resolved to focus heavily on evasion to avoid repeating my mistakes, though I immediately took massive damage right after engaging him.
Struggling to time my dodges, I found myself knocked down into the water at one point.
Realizing my health was already whittled down to a point where a comeback was unlikely, I decided to just stay put and let him finish me off so I could respawn fresh.
Racing back to the arena from the shrine, I tried to implement cleaner, slower positioning to practice perfect dodges. Unfortunately, he caught me with early hits once more, and despite sneaking in some damage and landing an immobilize spell, the heavy blows mounted up.
Recognizing I was outmatched on that attempt, I gave up and let the defeat take me back to the shrine, wondering why breezing through his first phase had suddenly become so difficult compared to my earlier tries.
Things finally clicked on the next run. Bypassing his opening and secondary attacks with clean, flawless perfect dodges, I caught him mid-air with a well-timed immobilize.
I followed up by summoning the Guangmou spirit to unleash the snake swarm while I kept my distance, dodging his long-range spear thrusts with pinpoint accuracy.
Even though I took a heavy hit that drained most of my health, I kept fighting aggressively, landing heavy blows and realizing that simple evasion wasn't enough, I needed to time my split-second dodges right at the moment of impact.
Landing another immobilize as his health bar bottomed out, I successfully triggered his transition into the giant snake form, entering phase two with much better health than my previous attempts.
To my surprise, I even started executing perfect dodges against his serpentine onslaught.
Despite performing better than ever before, his overwhelming power ultimately proved too much, brushing off my best efforts and taking me down like child's play, though I remained determined to finally conquer him.
All the pictures are take by me, from my gameplay. I might've taken help from the internet for some words/names/locations used in this post.
