Reed Eye (commonly referred to as Reed Rye in guides, databases, and community discussions) is a key gathering material and cooking ingredient in Arknights: Endfield. It’s especially important during limited-time events like Supply Exploration Day (active in Version 1.1 as of March 2026), where it’s required for daily meal deliveries (e.g., Emergency Meal objectives in the Supply Memo). Reed Rye is a hardy cereal crop used in recipes like Hub Emergency Ration or Valley Pie, and it’s a 2★ rarity natural item.
This guide covers all reliable ways to obtain Reed Rye: overworld gathering spots, farming via Eco-Farm, seed sources (for sustainable supply), and any vendor options. No major bugs were reported in recent patches—it’s mostly about knowing the spots or progressing facilities.
Reed Rye Overview and Uses
- Rarity: 2★
- Type: Natural/Plant (gathering resource)
- Primary Use: Cooking ingredient for event meals (Supply Exploration Day daily tasks), pharmaceuticals, or other recipes.
- Event Relevance: Required for Emergency Meal in Supply Exploration Day (alongside Buckflower and Hard Aggagrit). Gather or farm it to complete resource supply objectives for pass EXP and rewards.
- Stack Size: Standard (check inventory for exact).
World Location (Overworld Gathering Spots)
Reed Rye spawns as harvestable plants in the open world—look for tall, reed-like grass clusters with a gather prompt (usually glowing or interactable).
Main Confirmed Location:
- Originium Science Park: Cliffside Trail—This is the most consistent and accessible spot.
- Teleport to the nearest Travel Point (e.g., Mountain Path Slope or Cliffside Trail Bridge).
- Walk along the path/bridge area—multiple plants spawn here (some guides note 2-3 in one cluster on the left side).
- Often near glowbugs or other resources—easy to spot with exploration mode.
- Respawn: Natural respawn timer (daily or after area reload/fast travel).
Other Potential Spots:
- Scattered in Valley IV regions (check interactive maps for markers).
- Mountain paths leading to Origin Load Spring (some story-related areas have them).
Tips for Finding It:
- Use the in-game map filters or Guiding Light ability to highlight gatherables.
- Explore during events—Supply Exploration Day highlights needed items.
- If nothing spawns, fast travel away → return or log out/in to reset the area.
For visual help, community videos show exact spots (search “Reed Rye Location Arknights Endfield” on YouTube—many from March 2026 show Cliffside Trail clusters).
Vendor Location (Seeds and Potential Purchases)
Reed rye itself isn’t directly sold by vendors (it’s a wild/foraged item), but you can buy or obtain reed rye seeds for farming.
Seed Sources:
- Seed-Picking Unit (facility in your base): Convert gathered Reed Rye → Reed Rye Seeds (e.g., 1 Reed Rye → 2 Seeds in ~2 seconds). Unlock this unit early via base progression.
- AIC Factory Facilities, or crafting stations: Produce seeds from plants.
- Seed Merchants (mentioned in some guides):
- Originium Science Park area (near Cliffside Trail—check NPC vendors after unlocking the zone).
- Wuling City Seed Merchant (later regions, for bulk or event stock).
Once you have seeds:
- Craft farm plots in your eco-farm (base facility).
- Plant and harvest Reed Rye repeatedly (sustainable farm—apply fertilizer for faster growth and better yields).
No direct Reed Rye vendor exists (as of March 2026)—focus on gathering once or farming for unlimited supply.
How to Farm Reed Rye Efficiently for Supply Exploration
- Gather 1-5 from Cliffside Trail (quick run from TP).
- Use Seed-Picking Unit → get seeds.
- Plant in Eco-Farm (unlock via base upgrades).
- Harvest daily → craft event meals (e.g., Emergency Meal with Buckflower Powder + Hard Aggagrit + Reed Rye).
- Complete Supply Exploration Day dailies for rewards (Pass EXP, event currency).
Interactive Map Resources (for precise markers):
- Endfield.gg/map or endfieldtools. dev/interactive-map (search “Reed Rye” or filter plants in Valley IV / Originium Science Park).
- These show exact nodes—great for Delhi players on mobile during short sessions.
Reed Rye is straightforward once you hit Cliffside Trail—grab it wild early, then farm for events. If you’re stuck in Supply Exploration Day, prioritize this spot and base farming. Happy exploring in Talos-II!
