Duet Night Abyss Geniemon Farming

Geniemons are an important part of Duet Night Abyss (DNA) and all types of geniemons, especially the Inactive ones, are important.

There are three ways to get geniemons:

General Notes

It's not entirely clear that characters with the Tamer trait (e.g., Truffle) have any extra benefit, but might as well use them just in case. Those traits may actually only be for Dynamic quest assignments.
Shiny Geniemon do NOT require Shiny Geniemon to Ascend, just a "regular" one (either Miraculous or Ardent). Using a Shiny one to Ascend them does not seem to impart any benefits (?).

So save your extremely rare and expensive Yum-Yum Milk (one available possibly each season of Immersive Theatre) on Geniemon where you can't seem to find enough copies, such as Bro Boxie.
The IS a Shiny Bro Boxie! (see slide below) One randomly spawned for me in Lonza Fortress (slides 1-2)

Four copies of the same Trait on any type of Inactive can be used to upgrade to a higher Tier version of the Trait (you select one then sacrifice three to upgrade it). This can help you fill out your stickerbook of geniemon Traits, especially the gold tier traits.
Except the Erudite trait, trait colour does not matter when using them as fodder, so try to chose blue traits.
There's no point upgrading the Erudite trait unless you want to fill out your geniemon trait archive: A blue Erudite gives 48 XP and a gold Erudite gives 64 XP but requires 16 blue Erudite geniemon to Raise one.

Crafted Treats are expensive (they need Gold Dust which are used in vast quantities for a lot of critical crafting) so...

If the best chance is Yellow (usually Inactive Geniemon) I don't use a special Treat.
If it's a Shiny geniemon, I always use the best Treat of course.
Otherwise I may use a Treat to collect the geniemon if:

Once you have fed a geniemon, you do not have to wait to see if you succeeded (although I wouldn't exit the map/teleport).

Map Refresh

Geniemon locations in the open world are fixed, but the geniemon can wander in a loop.
Bro Boxie can help you locate them or check at a distance if there's a geniemon there.

The cooldown is quite long but automatically resets after a teleport. So if you are close to a teleporter, you can teleport to reset it then move to your next site.
It locks onto ONLY the nearest geniemon at the time you activate.

That means there could be more than one within range, just further off than the closest one.
Even if you get closer to another one, it will not change its marker until you reactivate its support skill.
If it did not lock on to anything and you now move and come into range of a geniemon, it may still not lock on to it (there may be a timer during which time it will pick up a geniemon, but this appears to be shorter than the cooldown).

Dynamic Encounter

If you send Partners to do a Rescue the Geniemon Dynamic Encounter, it appears you only get upgrade materials and not the geniemon.
Upgrade materials are theoretically worth more than a single geniemon, BUT you still want even blue Inactive Geniemon because it could have a trait you can steadily upgrade, or even end up being a gold-trait Geniemon (some traits are ONLY gold tier).
If you get close to a Dynamic Encounter, it triggers and if you leave the encounter ends entirely. So you can't really scout it to decide whether to capture the Geniemon or send Partners to try to do the Dynamic Encounter.
A Geniemon Rescue Dynamic Encounter is always located at a regular geniemon spawn location, but even if you have already cleared the map of geniemon, this encounter can occur and result in another geniemon spawned there.
Unlike Rescue missions in Commissions, the taming chance is apparently not automatic.

This MIGHT be just a UI glitch and you will always end up with success no matter what, just like a Geniemon encounter during a Commission. Needs more investigation for confirmation.

Commissions

If you want to try farming Geniemon, do a Commission like Capture. Once the target is Captured, a Rescue the Geniemon event has a chance to happen.
Typically these are Inactive Geniemon, but the capture chance is always 100%.
If you don't really need the Capture mission, just run an easy one where you can one-shot the capture target.
If you use Excavation, it appears a Geniemon encounter only spawns at the start of the second wave.

Geniemon Encounters typically appear after Commission objectives are met, so they will never spawn in wave 1 because once you meet the objectives (3 excavations), the Commission ends.
Even if you do more Continuations, you won't get any more Geniemon encounters.

Overland Geniemon Map (updated Fri-Dec-30 with Huaxu maps)

A Black Geniemon icon indicates where I've found a geniemon.
I flip it to an exclamation mark if I failed to catch that geniemon, and flip it back when I have caught it.
All locations refresh every 3 days

So if you noticed geniemons repopulated the game world on Friday, then you have Friday, Saturday, and Sunday to catch them. On Monday the map refreshes again.
When the map refreshes, some locations will have geniemons, some will not.
Try to clear the locations as soon as possible because a Geniemon Rescue Dynamic Event may overwrite a geniemon that is already at that location (needs verification).
Geniemon Rescue Dynamic Events are separate from this refresh cycle.

The official Discord has more detailed information about spawn zones and where certain types of geniemons might appear in the base game / Icelake region and the Huaxu expansion, but generally you just want to try to catch them all.

Supposedly 46 geniemons spawn per three day cycle for the original zones (Purgatorio / Icelake / Lonza Fortress) and 25 for Huaxu.
