Intro and Defeat Dialogue

Context lines from the encounter, extracted from game data.

  • Intro: "This place is now under the domain of the Tree." "Welcome." "You can go no further."
  • On defeat: "This place... from now on..." "<color=red>Kkekekekekekekeke...</color>"

How to Identify the Encounter

Use the opening localization line as evidence: "This place is now under the domain of the Tree.". The exact visual model remains unverified unless the asset map says otherwise.

Before the Fight

Open the linked build guide, confirm that its basic loop works without the missing core option, and preserve one defensive or repositioning answer. Continue only when the build can reset after a mistake.

How to Win

  • Observe the first verified call-out before committing.
  • Use the call-out as a warning, not as proof of an undocumented hitbox or direction.
  • Take the shortest safe punish after the cue resolves.
  • Reset positioning and resources before waiting for the next event.

Common Failure Reasons

  • Treating a dialogue event count as a count of attacks or phases.
  • Committing through a verified call-out before its visual response is understood.
  • Entering without a defensive or repositioning fallback when the preferred skill is absent.

Rewards and Drops

Verified drops are not available in the extracted data.

Builds that suit this encounter. The pairing is editorial analysis based on the weapon families' extracted traits - it is not an official tier list.

Tips

General encounter advice. Attack timings and exact mechanics are not yet published by TEAM HORAY, so treat these as starting points and confirm in-game.

  • The boss guards the Tree's domain - expect arena pressure that punishes camping a single corner.
  • Use the first cycle to learn its approach patterns before committing damage.
