Farming Endo and credits

Mods get stronger when you upgrade them. For that you need two things: Endo and credits. Early on, whatever you pick up along the way is enough. As soon as you want to max Primed or Galvanized mods, it gets expensive. This tutorial shows you the costs and the best farming spots for both currencies.

The most important terms in short:

Endo

Blue energy used to upgrade mods. Enemies drop it, missions reward it, and you get it from dissolved mods.

Credits

The standard currency of the game. You need them for fusion, for blueprints in the Market and for every build in the Foundry.

Fusion

Upgrading a mod in the Mods segment. Every rank costs Endo and credits.

Dissolve

You break down a mod you do not need and get Endo back for it.

Ayatan Sculpture

An Orokin artwork you find in missions. Filled with Ayatan Stars, you trade it to Maroo for a lot of Endo.

Credit Booster

A Market booster (e.g. “7 Day Credit Booster”) that doubles your credits for a while.

Rarity

The color of the mod: Common (bronze), Uncommon (silver), Rare (gold), Legendary (platinum). It decides how expensive fusion is.

Each new rank costs twice as much as the one before. The base price depends on rarity: 10 Endo for Common, 20 for Uncommon, 30 for Rare and 40 for Legendary mods. Credits follow the same rule with 483, 966, 1,449 and 1,932 credits as the base price.

Example mod	Rarity	Max rank	Endo	Credits
Vitality	Common	10	10,230	494,109
Serration	Uncommon	10	20,460	988,218
Intensify	Rare	5	930	44,919
Galvanized Chamber	Rare	10	30,690	1,482,327
Primed Continuity	Legendary	10	40,920	1,976,436

As you can see, a mod with 5 ranks is cheap and a mod with 10 ranks is expensive. That is the doubling at work. On a 10-rank mod, the last two ranks alone cost three quarters of the total.

Especially early on it is tempting to push everything to the highest rank. That is usually a waste. Here is a smarter approach:

• First upgrade the mods you really use in many builds, for example Serration, Vitality or Intensify.
• Mods with 5 ranks are cheap. You can max them early.
• On 10-rank mods, rank 8 or 9 is often enough. You get most of the bonus for a fraction of the cost.
• A lower rank also costs less mod capacity. Sometimes another mod only fits if one stays a rank lower.
• Do not upgrade mods for weapons you only level for mastery.

The game counts Endo as a mod drop, not a resource. That is why only the Mod Drop Chance Booster helps. Resource Boosters and Retriever mods do nothing for Endo.

Ayatan Sculptures are the easiest Endo source for beginners. You fill them with Ayatan Stars in the Mods segment and then sell them at Maroo’s Bazaar on Mars for Endo. Without stars you only get a fraction.

1. 01

   Find sculptures

   Many missions have a 15% chance to hide a sculpture somewhere. It looks like a normal pickup on the minimap, but you have to pick it up with the interact key.

2. 02

   Maroo’s weekly hunt

   Maroo’s Bazaar offers a weekly mission with a parkour room in the Orokin Tower or Orokin Derelict. A guaranteed sculpture waits at the end. It resets every Monday.

3. 03

   Collect stars

   Ayatan Cyan Stars and Ayatan Amber Stars are found in containers and lockers. Kuakas on the Plains of Eidolon drop them too.

4. 04

   Fill and trade in

   Insert all matching stars under “Ayatan Sculptures” in the Mods segment and hand the sculpture to Maroo.

Your first mission after the daily reset at 0:00 UTC gives double the end-of-mission credits. So do a mission with a high payout first, for example an Arbitration. This does not apply to The Index, bounties, the Zariman or Höllvania. More in Daily and weekly routine: what to do regularly.

• A Credit Booster doubles your credits. In the Market it costs 40 platinum for 3 days, 80 for 7 days or 200 for 30 days. Sometimes it is also a login reward.
• A Mastery Rank 30 player can hand out a Credit Blessing in the Relay: 25% more credits for 3 hours.
• Loyal Retriever for beast companions gives a 13% chance for picked up credits and resources to count twice.
• Prosperous Retriever only doubles credits, but with up to 18% chance. You get it from The Business in Fortuna.
• For Endo only the Mod Drop Chance Booster helps, not the Credit or Resource Booster.

• Netracells give credits from containers and Archon Shards, but no Endo. You farm other things there, see Netracells and Archimedea: weekly endgame loot.
• Sanctuary Onslaught only rarely gives small amounts of Endo. Arbitrations are much better for Endo.
• The Circuit in Duviri only gives 250 Endo as a repeated reward in normal mode. A bit more on the Steel Path, but it is not an Endo farm.
• Selling mods for credits gives very little. Dissolve them into Endo instead, or sell rare mods for platinum.

How to farm resources in general is explained in Resource farming: get there faster. More about Arbitrations in Arbitrations: rules, Vitus Essence and rewards, and about Teshin and Steel Essence in How to unlock and master the Steel Path.
