This is a traceable player route, not an in-house test or an official recommendation. Use it as a route to verify in your own run.
What the achievement asks
The public achievement description says to meet the tree with Perr. An older guide places the setup after Chapter II: speak with Perr around the carrot farm, then reach the floating-island tree.
Why current players may be confused
A newer community discussion says the relevant character may now be named Fel and can appear at the upper-left of the carrot fields. This conflicts with the still-visible achievement wording, so check both names instead of assuming your quest is broken.
- Check the upper-left area of the carrot fields
- Look for Perr or Fel depending on the displayed version
- Complete the conversation before pursuing the floating-island tree
Missable-state warning
Community reports disagree about later-chapter availability. Until the route is reproduced on version 1.0.21, make a backup before advancing past the relevant chapter and treat the old guide as a clue rather than a guaranteed current sequence.
