Start on the west side of The Hub and check the interaction prompt on plants near Citrome patches: a prompt reading “Umbraline” identifies the resource. That location and the reported 30-minute node respawn come from a community guide, not an official confirmation. For a broader search, use the official Map Tools to find resources and plan a route.
Where to look for Umbraline
A community guide places Umbraline on the west side of The Hub, growing near Citrome patches. It does not provide verified coordinates, so treat this as a starting area rather than a guaranteed route. The guide is titled Completing the crafting manual: Where to find Umbraline and Firebuckle.
How to tell Umbraline from Citrome
The same guide says the two plants look alike. Check the interaction prompt before gathering: look for “Umbraline” rather than relying on appearance alone.
Use Map Tools to search and plan
The official Arknights: Endfield Game Tools Guide describes Map Tools for searching, filtering, and locating points of interest, including resources and facilities. The official announcement Arknights: Endfield Game Tools Updated, dated September 22, 2026, says the Dreamscape of Wind and Snow update added a new area and position markers. It also describes route planning that can combine resource collection with Aurylenes and storage crates. You can also open Game Tools through the in-game Protosync.

The third-party Endmin.moe interactive map currently lists 23 Umbraline markers, but the page view available here did not expose their coordinates or descriptions. That live marker count is not a total of Umbraline in the game, and it may change as the game and map are updated.
Can you grow Umbraline in the Eco-Farm?
Community comments report that planting Citrome in the Eco-Farm can produce Umbraline at harvest. The available reports do not establish a dependable yield or timing, so consider cultivation an alternative to trying if repeated overworld searches are inconvenient—not a guaranteed supply method.

How long do Umbraline nodes take to respawn?
The community guide reports that gathering nodes respawn within 30 minutes. No official confirmation of that interval is established here, so do not rely on it as a guaranteed timer for the current version.
