Acolyte Lei Ting is the second of the four Acolyte Masks and the one most likely to be locked behind a tool you skipped. The fight itself is a lightning landing check — leave the marked circles, punish the landing — but the route to it runs through the Flaming Mane and a bramble gate near Old Man Gen’s House.

Location and unlock

Lei Ting is an optional boss in Pangzhen, Chapter 4, fought at Old Man Gen’s in the south-west cliffside and slums. The Acolyte Masks guide gives the access detail: the mask sits around Old Man Gen’s House, and the obstacle is bramble that requires the Flaming Mane to burn away near the Pond of Fading Song.

That means the fight has a soft prerequisite: defeat Flame at the Lion Dance Hall, take the Dormant Flaming Mane to Lei Dang at Jingyang Hall, and use the repaired Flaming Mane on the brambles. Without it, you can reach the area but not the encounter. The Pangzhen walkthrough and the Acolyte Masks guide track the chain.

Reward and missable warning

The drop is Leiting’s Thunder Mask, one of the four Acolyte Masks. All four are required at the Four Guardians’ Mirror in frozen north-west Meigu Lake to open the Phantom Illusionist Ruins, which contains Long Pillar 4 and the Eye statue.

The mask is part of the true-ending chain. The practical deadline is the Green Serpent House door in Pangzhen, the first hard cutoff. Missed optional bosses remain in post-story free roam, but the mirror route closes earlier. Boss drops are one-per-run.

Fight plan: leave the circles, punish the landing

The boss table’s line is “leave marked circles; punish landing.” That is the fight.

Leave the marked circles. Lei Ting’s lightning is telegraphed by ground markers. Do not stand in them to finish a combo; the markers are the hit, and the safe response is to move out and re-enter after the strike. If multiple circles overlap, leave the whole cluster rather than trying to thread between them.

Punish the landing. His aerial recovery is the damage window. Wait for the landing, then take a short combo. Do not chase him into the air or commit to a long animation while he is still descending.

The loop is: bait the lightning, leave the marker, re-enter on the landing, punish, reset. No HP value, phase count, or named moveset is published, so treat it as a single-phase timing fight.

Attack tells

No full colour map or named moveset is published. The documented tells are the marked circle and the landing; the rest is universal grammar.

Tell Response Punish
Marked ground circle Leave the area Re-enter after the strike
Aerial descent Wait for the landing Short combo
Blue-flash hit Parry Sha-Chi pressure
Red-flash hit Dodge Do not block or parry

The marked circle is not a parry prompt. It is a ground hazard; move out, then look for the landing.

Bring a mobile main with a short punish. The fight is about leaving a small area and re-entering quickly, so a weapon that commits to a long animation will either eat the lightning or miss the landing. A guard-break option is secondary.

No elemental weakness is documented for Lei Ting. The mask’s element is Thunder in the Acolyte table, but that describes the mask, not a boss vulnerability. Do not build around a status on that basis. The best builds guide covers the mobile options for Pangzhen.

Common mistakes

  • Finishing a combo inside a marked circle. Leave first; the marker is the hit.
  • Chasing him into the air. Wait for the landing.
  • Missing the Flaming Mane gate. The bramble blocks the encounter.
  • Skipping the Lei Dang hand-in. The Dormant Flaming Mane is not the tool.
  • Treating the mask as optional flavour. It is a key to Long Pillar 4 and the Ruins.
  • Leaving Pangzhen before the Green Serpent cutoff. The mirror route closes.

Sources & confidence

The Old Man Gen’s location, south-west cliffside access, Flaming Mane bramble gate, marked-circle dodge, landing punish, and Thunder Mask reward come from the site’s Acolyte Masks and Pangzhen material, cross-checked against KeenGamer’s boss list. The Flaming Mane’s bramble-burning role comes from the Phantom Edges table. No HP value, phase count, named moveset, or colour map is published for Lei Ting, so the guide stays with the documented circle-and-landing plan.

A short, practical clear of Xie Qiudong, a Pangzhen story boss on the route to Chang Hong. The emphasis is on the fight’s real friction — the camera — with advice on lining it up before committing, plus when to lean on parry and dodge pressure instead of hunting a perfect read. Useful if the healer is draining your attempts rather than teaching you a clean pattern.
