Many resource caches lie abandoned and unclaimed on Deimos. Find them and they are yours.
This is one of the 9 possible bounties that can show up on Mother's bounty board in the Necralisk. This bounty has the Tenno find a hidden supply cache, and always ends with the Cache Retrieval stage. Below are the unique dialogue lines that are heard when beginning and ending the bounty, and when running the different stages. The Assassinate, Excavation, and Hive Extermination stages do not seem to appear for this bounty. All five possible stages are listed below.
Mother: "Over the years many expeditions of both Grineer and Corpus have become trapped on Deimos. Caches of resources left behind by the survivors still dot the surface. See what you can find and bring back. Loid will show you where to look."
(after entering Cambion Drift) Loid: "Scan logs have registered a substantial cache of lost resources in this area."
Otak: "Time to make some new friends, best brush your teeth! Wait – do you even have teeth?"
Otak: "Maybe you could use a Purifier? The cache might be covered up by squelchies!"
(upon completing bounty stage with bonus) Loid: "That is a positive wealth of data, but sadly not the data we are looking for. Nonetheless, good work, Tenno."
(upon completing bounty stage without bonus) Loid: "Some useful data was revealed, but the primary cache has not been located. Keep looking, Tenno."
Loid: "Proximity alert. Multiple Infested aggressors. Secure the area to continue with cache reclamation mission."
(upon completing bounty stage)1 Loid: "Excellent work, Tenno. With the Infested so comprehensively out of the picture, you should be clear to proceed."
Protect the Corpus Scientist
Loid: "The Corpus researcher Latrox Une is in the area. Seek his assistance for cache reclamation."
(upon completing bounty stage with bonus) Loid: "Latrox has his uses, but he seems clueless about the location of any caches. He is likely lying to keep them for himself. Corpus is as Corpus does."
(upon completing bounty stage without bonus) Otak: "Well, friend Latrox has marked off a few places NOT to look. I guess we keep going to the other places…."
Protect the Grineer Squad
Loid: "I have located a squad of Grineer survivors in the area. Questioning them may assist in finding any abandoned loot."
(upon completing bounty stage with bonus) Loid: "Given the poor performance of those Grineer, it's a good bet they haven't found any caches lately. Keep looking."
(upon completing bounty stage without bonus) Otak: "Okay, so Mr Grunty waved his fist and said something rude when I asked him about caches, so I don't think he knows about any."
Bounty end (Cache Retrieval)
Otak: "Oh, hey, there's a cache near here. Maybe it's the one we're looking for?"
(upon completing the bounty) Mother: "Loid tells me you have a cache unlocked. A decent enough haul for our collective efforts. I am not sure what we would do without these occasional windfalls."
