Single-source snapshot from 2026-10-15. Genus-wide chest, achievement and trial lists do not establish a guaranteed route for this individual pet. Shop, event, server and version availability can differ. Missing probabilities, prices and guarantees are not filled in.
The reward extract has no complete field-soul source for this pet; the wiki adds a separate lead. The two records stay separate. A wiki lead does not become a confirmed reward-table drop or proof that an unreleased map is open.
