You Loong is fought twice, and the two encounters are not the same fight. The first is an optional Pangzhen Waterways duel against a water fighter who hides and surfaces. The second is a frenzied rematch at Blackwater Dock in Meigu Lake, where he fights with a trident and a much more aggressive close game. This page covers both, in route order, and flags the one trophy detail that catches people out.
Location and unlock: two separate encounters
Pangzhen — Waterways. The first You Loong is an optional boss in Pangzhen, Chapter 4, found in the Waterways. The boss table says to punish him when he surfaces and to beat him before Flame at the Lion Dance Hall. The region route lists him among the optional Pangzhen fights, alongside Acolyte Lei Ting and Zhu Yuan.
Meigu Lake — Blackwater Dock. The second is You Loong (frenzied), an optional boss in Meigu Lake, Chapter 7, fought at Blackwater Dock. The Meigu route places him in the early lake sweep, near the Shallows Dock and One-Eyed Isle, and lists his drop as the Loong Trident plus a High-Power Pump.
They are separate encounters with separate rewards. Beating the Pangzhen version does not remove the Meigu fight, and the Meigu fight does not require the Pangzhen kill.
Reward and missable warning
The Pangzhen encounter drops You Loong’s Deluge, an Artifice Phantom Edge. It fires a water jet that applies Wet, works as an anti-fire tool, and its temper adds steam. That makes it a natural pickup before Flame, which is why the boss table says to beat him first.
The frenzied Meigu encounter drops the Loong Trident, a Ranged Phantom Edge. Its charged throw applies Wet and forces water/snow hiders out, which is a utility effect as much as a damage one.
Both fights are optional. The trophy detail is the important part: Master of the Misty Waters requires the Meigu/frenzied You Loong, Yan Qiansui, and the One-Eyed Archer. The Pangzhen You Loong does not count toward that trophy. If you are chasing it, the Blackwater Dock kill is the one that matters.
The broader deadline is the Mirage Estate cutoff. Meigu and the Mountain must be finished before the Green Serpent House door. Boss drops are one-per-run.
Fight plan: surface punish, then trident circles
Pangzhen — punish the surface. The documented plan is one line: punish him when he surfaces. He is a water fighter, so the fight is about waiting out the submerged phase rather than chasing him into the water. Stay near the centre of the arena, keep him in view, and convert the surface window into a short combo. Do not dive after him or commit to a long animation while he is out of reach.
Meigu — circle the trident, punish the thrust. The frenzied version is a close-range trident fight. Circle him rather than backing up, and punish the thrust after it commits. The trident’s reach makes a straight retreat worse than a lateral step. The same rule as most Polearm fights applies: do not stand on the point’s line.
No HP value, phase count, or named moveset is published for either encounter. Treat each as a single-phase fight and learn the surface/trident rhythms from the fight itself.
Attack tells
| Tell | Response | Punish |
|---|---|---|
| Submerged / off-arena (Pangzhen) | Wait, keep the centre | Punish the surface |
| Trident thrust (Meigu) | Circle laterally | Punish the recovery |
| Water projectile / Wet application | Sidestep, do not stand in it | Re-enter after the cast |
| Blue-flash hit | Parry | Short counter |
| Red-flash hit | Dodge | Do not block or parry |
The repo does not publish a colour map for either You Loong fight. The documented tells are the surface window and the trident thrust; the rest is universal grammar. Wet is an edge interaction, not a confirmed boss weakness, so do not assume a lightning or frost build is “correct” here.
Recommended weapon and build
Bring a mobile main for both fights. The Pangzhen encounter is about repositioning around a target that leaves the arena; the Meigu encounter is about circling a long-reach weapon. A fast weapon with a short punish fits both.
The You Loong’s Deluge edge is the Pangzhen reward and the anti-fire tool for Flame; the Loong Trident is the Meigu reward and a Wet applicator. Neither is required to win the other fight. No elemental weakness is documented for You Loong himself. The best builds guide covers the mobile options for Pangzhen and Meigu.
Common mistakes
- Chasing him into the water in Pangzhen. Wait for the surface.
- Backpedalling the trident in Meigu. Circle laterally.
- Killing only the Pangzhen version and expecting the trophy. Master of the Misty Waters counts the Meigu/frenzied kill.
- Skipping the Pangzhen fight before Flame. You Loong’s Deluge is the anti-fire edge.
- Standing in the Wet projectile. It is a setup tool, not a damage race.
- Leaving Meigu before the Mirage cutoff. The lake’s optionals close at the Green Serpent House.
Sources & confidence
The two locations, optional status, rewards, surface-punish instruction, trident-circle instruction, and the “beat before Flame” route note come from the boss table and the Pangzhen and Meigu routes, which draw on PowerPyx’s played walkthrough and KeenGamer’s boss list. The Master of the Misty Waters trophy requirement and the Pangzhen-does-not-count caveat come from the compendium’s achievement section. The Deluge and Trident effects come from the Phantom Edges table. No HP value or named moveset is published for either encounter, so the guide stays with the documented surface and thrust plans.
