For early Endo, dissolve genuinely spare Mods, collect Ayatan treasures, and play accessible missions with Endo in their reward tables. Later, compare the bounties and endless modes your account has unlocked. The best route is the one you can complete reliably while funding a specific Mod upgrade.
Endo powers Mod Fusion; the process also requires Credits. The official introduction to Endo explains Mod dissolution and rank-based upgrading. Source checks for this guide were completed on October 13, 2026. No hourly farming benchmark was performed.
01
Set the upgrade target before the farming target
Open the Mod you want to improve and inspect the cost of the next useful rank. Decide whether you need that rank immediately or whether a smaller upgrade already makes your loadout functional. Keep enough Credits for Fusion as well as your other crafting plans.
A costly final rank can wait when several basic Mods remain weak. For example, a player unable to finish a normal mission may gain more practical comfort by improving a useful defensive Mod and the main weapon's damage setup than by concentrating the entire budget into one impressive maximum-rank card.
The decision is about completing your next mission. Do not farm an arbitrary huge Endo total because a late-game build screenshot contains expensive Mods. Write down the next upgrade, its displayed cost and the equipment on which you will use it.
02
Begin with spare Mods already in your inventory
At the Mods console, review duplicates and select the copies you are prepared to lose. Use the Endo dissolution option and inspect the confirmation before accepting it. Selling for Credits is a different action and solves a different shortage.
Keep a useful copy of the Mod, and think before dissolving rare or specialized extras. A duplicate may have a future use, including a different rank for a tight-capacity build. Do not apply a blanket “dissolve everything” rule to a collection you have not reviewed.
This is a good first step because it converts resources you already earned. It is not an unlimited independent farm: once those spare copies are gone, further Endo requires additional play or other sources. Check the resulting total before deciding how much more farming is necessary.
03
Use Ayatan treasures as a separate Endo reserve
Maroo's Ayatan activity offers another route. Visit Maroo's Bazaar on Mars when available, ask about Ayatan treasures, and complete the offered hunt. In its Nightwave instructions update, Digital Extremes also explains that stars can be inserted through the Ayatan Treasures section of the Mods workbench.
Inspect the sculpture and its available sockets before converting it. Compare the displayed Endo value and decide whether you want to fill the remaining sockets first. Keep the distinction clear: a sculpture in your inventory is potential Endo, not Endo already available to spend at Fusion.
Prepare for the hunt's movement and objective rather than assuming combat strength alone completes it. If you struggle, learn the route and controls before committing repeated attempts. Treat the weekly opportunity as one part of your routine; do not assume repeating an already-claimed weekly reward creates another identical payout.
04
Choose an accessible mission with a verified reward
The current official PC drop table lists Endo among the Rotation A rewards for Everest, Earth's Excavation mission. That makes it a concrete early option when you can protect and power the excavators.
The table lists possibilities, not a guarantee that each rotation pays Endo. Mission rewards, enemy drops and spare Mods collected during the run contribute through different mechanisms. Keep those totals separate when deciding whether a route works for you.
| Account stage | Route to consider | Main requirement |
|---|---|---|
| Early progression | Spare Mod dissolution | Carefully reviewed duplicate collection |
| Early accessible missions | Everest or another verified Endo reward mission | Ability to complete the objective |
| Ayatan access | Maroo's hunt and collected sculptures | Complete the hunt; inspect socketing value |
| Zariman access | Bounties whose current table includes Endo | Appropriate quest access and bounty completion |
| Sanctum Anatomica access | Current Cavia bounties with Endo rewards | Appropriate story progress and a stable loadout |
05
Let later bounties serve more than one goal
The Angels of the Zariman notes include Endo among Zariman bounty rewards. The Whispers in the Walls notes likewise include it in the Cavia bounty reward pool. Check the current bounty panel before choosing a tier or mission.
These routes are useful to compare when you also need their other progression rewards. A session that gives the standing or materials you were already pursuing can be worthwhile even if its Endo result varies.
Avoid choosing a difficult bounty solely because its possible reward looks larger. Include failures, travel time and objective requirements in the comparison. A reliably completed lower-pressure activity can support your account better than repeatedly failing a nominally richer one.
06
Evaluate advanced farms with their actual conditions
You will encounter recommendations for Arbitrations, Sedna arenas and specialized coordinated squads. Those suggestions can involve access gates, particular roles and mechanics that are absent from a beginner loadout. This page does not claim a tested current ranking among them.
Before following an advanced method, ask what its quoted result includes. Was the group coordinated? Was an event or booster active? Were loading and setup counted? Were Ayatan sculptures valued as fully socketed even though the required stars were not collected in that session?
Treat an impressive Endo-per-minute claim as a result under stated conditions, not an unconditional property of the mission. The official drop table helps verify reward contents, but it cannot tell you how quickly your own squad completes the objective.
07
Keep a simple comparison log
Compare only routes you can already access. For each session, note the elapsed time, directly awarded Endo, sculptures obtained and spare Mods you choose to dissolve. Record conversion separately so the same reward is not counted once as a sculpture and again as Endo.
After several sessions, look for the route that makes useful progress without forcing frequent failures or long preparation. You may prefer a slightly lower Endo result if the same session also advances a faction or provides materials for a planned build.
Stop when the upgrade target is funded. Return to the Mods console, apply the intended rank and check that the upgraded card still fits. The builds guide explains capacity planning; the Legendary Core guide covers a different, rare way of handling a major Mod upgrade. Neither requires treating every Mod in your inventory as an urgent maximum-rank project.
