Threadbound Great Tree is the last preparation stop

Community-reported

Clear Mirrorwood’s mist, activate Threadbound Great Tree and approach the flower field beneath the hanging threads. The fight starts beyond the mist. Recheck unfinished local hand-ins before committing; the forest walkthrough separates reported quest cutoffs from confirmed route directions.

Lady of the Twin Serpents: finish defending the string

Community-reported

All Things How describes rapid blade sequences, a lunging double-cut and a flurry with a heavier final strike. Its advice is to continue defending through the follow-up, dodge the red-flash blow and move away when serpents emerge. Treat move names below as visual descriptions from that report, not official ability names.

Fast two-cut rush

Response
Defend both cuts.
Opening to look for
After the follow-up ends.
Common mistake
Attacking after only the first hit.

Light flurry with a heavy finish

Response
Prepare a parry or dodge for the last strike.
Opening to look for
Once the finisher has passed.
Common mistake
Holding guard and assuming every hit behaves alike.

Red flash or emerging serpents

Response
Dodge the red strike; leave the serpent’s path.
Opening to look for
After the danger clears.
Common mistake
Trading hits while the field attack is active.

Sacrificial Serpent: leave the spin and burst

Community-reported

The same report describes a fresh bar after the transition. In serpent form she can spin in the air, descend, rush along the ground and send serpents outward. Retreat from the spin or burst, then defend as she closes again. Running away indefinitely is not the report’s answer to her chase.

The later form has a different name bar and an airborne approach across the flower field. Compare the changed silhouette and distance before applying advice for the first phase.

Make each attempt answer one question

Editorial guidance

If the first phase consumes your medicine, focus the next attempt on finishing one troublesome string without retaliating early. In the second phase, distinguish the closing rush from the outward burst before choosing an attack.

This is editorial practice guidance. No fixed gourd count, required weapon, boss health total or universal timing window is asserted here; the source’s damage examples are tied to its stated difficulty and setup.

Rewards and the move to Village of Lu

Community-reported

All Things How’s reward report lists White Serpent & Crimson Viper, Resonance Talisman and Broken Illusory Pipa. The next arrival is Place of Awakening in Village of Lu. Ring that bell, then follow the bridge route to Jewel; keep the broken Pipa for its later repair quest.
