Search Deimos for valuable geological core samples.
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 extract core samples from the moon, and always ends with the Excavation stage. Below are the unique dialogue lines that are heard when beginning and ending the bounty, and when running the different stages. The Cache Retrieval, Extract Samples, and Liberation stages do not seem to appear for this bounty. All five possible stages are listed below.
Mother: "It is vital that we gain a proper understanding of the Infestation on Deimos in order to protect the Heart. Loid will instruct you on how to procure geological core samples in relevant areas. This would be a great help to me."
(after entering Cambion Drift) Loid: "Geological core samples can be procured nearby that will reveal vital data about Deimos infestation levels. Please—"
Otak: "Just ignore them and blast Infested, it'll do more good!"
Loid: "There is an apex Infested in this area that you'll need to deal with before you can take a core sample. Prepare some bait and draw it out."
(upon completing bounty stage with bonus) Loid: "Taking down the apex alone would have been sufficient. Just had to prove yourself, hmmmm?"
(upon completing bounty stage without bonus) Otak: "The big puppy is taking a nap! You tired him out good, Chip. And you got a core sample, too!"
Loid: "Proximity alert. Eliminate local Infested aggressors in order to procure a core sample."
(upon completing bounty stage)1 Otak: "Now THAT'S all done with, I suppose you could grab a core sample."
Protect the Corpus Scientist
Otak: "Contact our Corpus friend Latrox! He can help you get a core sample if you protect him!"
(upon completing bounty stage with bonus) Loid: "Excellent. Latrox has collected a number of samples on our behalf. Well done, Tenno."
(upon completing bounty stage without bonus) Loid: "Latrox has now routed core sample data to us, Tenno. He does have his uses."
Protect the Grineer Squad
Otak: "There's some Grineer survivors workin' round here that might help out; I should have baked cookies!"
(upon completing bounty stage)2 Loid: "Well done, Tenno, that little fracas has secured us a core sample from the grateful Grineer."
Bounty end (Excavation)
Loid: "Based on the other core samples, I have located the best place to get the final set. Proceed to the excavators."
(upon completing the bounty) Mother: "I'm told you have extracted a set of core samples. Good work, Tenno. I believe we're done here."
