Egg-exclusive Prismana: Fenmane, Infergon and Spark Elf
Prismana Fenmane comes from homeland level 10, Infergon from Season 1 rank 12, Spark Elf from its event. Each egg's one source, and what can still change.
The short version
- Reaching homeland level 10 awards a Prismana Fenmane egg, and that egg is currently the only way to get Prismana Fenmane.
- The Prismana Infergon egg is a Season 1 reward only. You earn it through stamps in the Season Journey when you reach season rank 12.
- The Prismana Spark Elf egg is free from the Spark Elf X Aniimo event, but both its quality and the exact way you earn it are not settled.
- The Fragrant Journey, a side questline after the campaign, ends with a hidden Prismana Iris egg once you turn in fragrances after unlocking Tide Blossom Coast.
- Umbra (Dark) Prismana forms come only from Prismana eggs taken in Egg Heist, and those eggs are guaranteed to hatch an Umbra Aniimo.
A few Prismana Aniimo can't be caught. You can't find them roaming or roll them from a common pool. Each one comes from a single egg, and that egg comes from one place: a homeland milestone, a season rank, an event, or a questline.
This guide goes through them one at a time. Prismana Fenmane, Prismana Infergon and Prismana Spark Elf come first, because those are the eggs you have to plan for. Then come the quieter ones: a hidden Iris egg, the battle pass Prismana eggs, and the Egg Heist eggs, which are the only route to Umbra forms.
Prismana Fenmane egg: homeland level 10

Reaching homeland level 10 awards a Prismana Fenmane egg. Right now that is the only way to get Prismana Fenmane. You won't run into one anywhere else, so if you want it, levelling your homeland is the whole plan.
There's no event window or season deadline attached to it. It's a milestone, so you can reach it at your own pace. Fenmane's skills and evolution have their own guide on this site. This page only covers where the egg comes from.

Prismana Infergon egg: Season 1, rank 12

Prismana Infergon is only obtainable as a Season 1 reward. The egg comes from stamps in the Season Journey, and you earn it when you reach season rank 12.
That makes it the most time-sensitive egg on this page. Fenmane waits for you. Infergon is tied to Season 1, so you have to reach rank 12 while that season is running.

Prismana Spark Elf egg: the Spark Elf X Aniimo event
Prismana Sparkelf (also written Spark Elf) is a new Aniimo. You get it from an egg awarded through an event's personal goals. The event is Spark Elf X Aniimo, and the egg is free.
The details around that egg are not settled. Its quality is given both as Elite and as a guaranteed perfect potential rating. How you earn it is even less settled. It is described as collecting 200 fire bolts or points, as collecting 500 fire sparks or points earned passively through standard play, as maxing the personal Fire spark path for a perfect one, as completing the event track, as cumulative daily check-ins, and as completing daily quests during the event. The event itself has a dedicated guide on this site. The point for this page is simpler: this Prismana comes from the event egg and nowhere else.
Prismana Iris: the hidden egg at the end of the Fragrant Journey

There is one more single-source Prismana egg, and it's easy to miss. The Fragrant Journey is a side questline that opens after the campaign. It ends with you turning in fragrances after unlocking Tide Blossom Coast, and the reward is a hidden Prismana Iris egg.
You don't get it for finishing the story. You have to go back and complete the side questline.
Battle pass Prismana eggs: Handbook, Flamentus and Formentus
The battle pass, called the Companion Handbook or Companion Manual, is another source of Prismana eggs. The premium Advanced Companion Handbook gives you early access to the season's featured Prismana Aniimo by awarding an exclusive Prismana egg at level 10. Which egg it is varies across seasons and versions.
What the level 10 egg actually is right now is not settled. The Standard Edition free track is given as granting a Fulmintis egg, arriving sooner or later depending on your story progress, and as the only way for free-to-play players to get one. The same level 10 egg is also given as an Incredible Flamentus Egg, and the advanced edition is said to award a Prismana Flamentus egg. Fulmintis also comes from eggs, including eggs from farming RV trips, so whether the pass is really the only free route to it is unclear.
The chosen Battle Pass Prismana egg hatches a Perfect-potential Aniimo, such as Prismana Formentus. The guarantee appears in the item description but not on the hatching screen. If you want to check before you hatch, read the item.

Egg Heist eggs and Umbra Prismana forms
Dark Prismana forms, also called Umbra, come only from Prismana eggs taken in Egg Heist. Those eggs are guaranteed to hatch an Umbra Aniimo. No other egg on this page gives you an Umbra form, so Egg Heist is the only place to look for one.
More broadly, free in-game and special events can reward unique, time-limited Aniimo variants. Spark Elf is one example. Any event that offers a variant egg works the same way: if you miss the window, you miss the egg.
Where to start
Sort these eggs by deadline. The Infergon egg needs season rank 12 during Season 1, and the Spark Elf egg needs the event to be live, so do those first. The Fenmane egg at homeland level 10 and the Iris egg at the end of the Fragrant Journey will wait for you. If you want an Umbra form, go to Egg Heist, because no other egg gives you one.
