How Evolution Works
Most Aniimo can evolve. Evolution moves a creature from one stage to the next along a fixed line, changing its stats, its skills and — importantly in Aniimo specifically — the form you take when you twine with it.
The game defines three stages, and the official Aniimo index uses them as a core filter alongside element and role. That is the clearest signal that stages are a primary dimension of the game rather than a cosmetic progression: you can browse the entire dex by stage, the same way you browse by element.
Two things make Aniimo's evolution structure different from what you may expect from other creature games:
- Stages are named, not numbered. Lumin, Gamma and Nova are the three stages. The official Chinese edition of the wiki labels the same progression as a three-step route (newborn → growth → mature), and the official English index names the stages Lumin / Gamma / Nova.
- Not every creature passes through all three. Some Aniimo reach their final form at Gamma. Others start at Lumin and go straight to Nova. The stage a creature sits at is a property of that creature, not a universal ladder.
The current launch build has 29 evolution lines and 54 evolution routes. The complete checklist is below, but the evolution screen remains the final word for the creature in your roster: it reflects your build, shows whether an extra condition has registered and prevents you from spending the wrong stone.
How to Evolve an Aniimo
Evolution in Aniimo is never automatic. Nothing evolves in the background while you play, and the option sits deep enough in the menus that plenty of players miss it entirely for their first few hours. You trigger it yourself, and it always starts from the same screen:
- Open the main menu. Escape on keyboard, or the button in the top-right corner on controller and touch.
- Select Aniimo Management from the top row of icons — it sits between the inventory and the map.
- Pick the Aniimo you want to evolve to open its stat display.
- Find the Evolve icon. It is near the bottom right, just left of the Level Up button: a small circular cat-shaped icon with arrows pointing up. It is easy to skip past because it reads as part of the Level Up control.
- Open the evolution screen by selecting that icon. This is the page that lists the creature's requirements and shows its full evolution line.
- Confirm with Evolve. A second Evolve button at the bottom of that screen performs the transformation once every requirement is met and the button is active.
When a creature meets its conditions, a quick-evolve popup appears on its own and you can confirm straight from it without walking the menus again.
Where to read the requirements
Requirements live on the evolution screen, not in a separate codex. Open the screen for a specific Aniimo and the full checklist for that creature appears in the upper-right; every line item has to be satisfied before the Evolve button lights up. That screen is also the only place with the real numbers, so it beats any guide, including this one.
The two families of requirement
Post-launch play has settled into two broad patterns:
- Level thresholds. The common case — reach a target level and the creature is ready. Each creature sets its own number, and the evolution screen states it.
- Level plus a task. Some creatures need a mission completed on top of the level. Emberpup is the one the game uses to teach this: it will not evolve until you finish a Sanctum, which is the game showing you that non-level conditions exist at all.
Level Up and Evolve are separate buttons that sit side by side and do completely different jobs. Level Up raises a creature's stats within its current form; Evolve changes the form itself. Levelling a creature never quietly satisfies a mission requirement for you.
The two starters are a special case: their evolutions are gated behind main-story progress, not level and not materials. If your Helion or Lunara has met every visible requirement and the Evolve button is still greyed out, story progression is the reason. Grinding levels and hoarding items will not move it — advance the story instead. Put the resources you would have spent forcing it into a different team slot.
Lumin vs Gamma vs Nova
Stage changes more than stats — an evolved Aniimo gives you a different set of skills to twine with.
The three stages form a progression of capability. What follows is what distinguishes them, based on how the official index groups creatures and what changes across a line.
| Stage | Position in the line | What it means in practice |
|---|---|---|
| Lumin | First stage | The starting form of that evolution line. Lower base stats, fewer skills, and the form you catch in the wild most often. Many Lumin Aniimo are the ones you will twine with for mobility early on. |
| Gamma | Second stage | A developed form — stronger than Lumin across the board. Some lines treat Gamma as their final stage rather than continuing, so a Gamma Aniimo is not necessarily an unfinished one. |
| Nova | Final stage | The end of the line and generally the strongest form of that creature. Nova Aniimo carry the highest base stats in their line and the most complete skill sets. |
Why stage matters beyond stats
Stage is not just a power level. Because twining uses the Aniimo's skills, mobility and trait, evolving a creature changes what you can do while twined into it. A Nova form is not simply a bigger number — it is a different set of tools. That is the main reason to care about evolution in Aniimo relative to other creature games, where evolution is often just a damage increase.
Dual-element Aniimo and stage
Some creatures carry two elements, and those tend to appear at later stages in their lines — the Fire/Dark and Water/Ice combinations are the examples to look for. Evolving into a dual-element form changes your matchup profile in both directions at once: you resist more, and you threaten more. These are consistently worth prioritising.
Evolution Lines Explained
An evolution line is the chain of creatures one Aniimo grows through. Lines are fixed — the creature at the end of a line is determined by where you started, not by choices you make mid-game (aside from branching, covered below).
Three shapes show up repeatedly:
- Two-stage lines — a Lumin that becomes a Nova, with no Gamma. Fast to complete and often the strongest early-game option, because you reach final form sooner.
- Three-stage lines — Lumin to Gamma to Nova. The classic progression. Slower, but the payoff at Nova is a fully developed skill set.
- Long lines — some lines run through several creatures before settling, with intermediate forms at different stages. The Wind line starting at Chirpi is a good example of a line that passes through multiple creatures and shifts role as it goes.
You can see every line laid out per creature in the full Aniimo list, which groups the dex by number so related creatures sit together. The Tier List ranks the end-of-line forms specifically, since those are the ones worth building toward.
Worked example: the Celestis line
The Celestis family is the clearest example of a short, quest-gated line, and it is worth knowing because it breaks the assumption that every line moves at its own pace through levels alone.
Celestis is a two-stage line: it goes straight from its Lumin-stage form to its final Nova-stage form, Stellarys, with no Gamma step in between. The evolution is not unlocked by levelling. It opens through the quest chain that runs out of the Forest of Falling Stars, north of your first Outpost, and it asks for three things at once:
- The Celestis you want to evolve must reach Aniimo level 18.
- You must defeat Alpha Stellarys — beating the alpha is what unlocks the evolution at all, so it is a gate, not just a step.
- The evolution itself costs Night Stone x1, the material Dark-type evolutions use. One stone per evolution, so raising more than one Stellarys means collecting more stones.
The line's evolution material is Starine, the star-shaped fruit found around the Forest of Falling Stars. Players report needing at least 20 of it for the quest chain that opens the line, and the same material is used to level Celestis-family Aniimo — including Stellarys — outside of combat, so it is worth collecting whenever you pass it rather than only when a quest asks.
Read that sequence as the template for gated lines generally: find the region, run the quest chain, beat the alpha, then pay the material. Your level gets you eligible; the alpha encounter is what unlocks the button.
Numbers in the dex are grouped by evolution line, not alphabetically. Adjacent numbers are usually related creatures. That is why NO.001 Emberpup, NO.002 Flameruff and NO.003 Scorchhowl sit together — they are one line.
Branching Evolutions
Branching lines are the one evolution decision you cannot undo, so it is worth checking both paths first.
Not every line is a straight chain. Some creatures evolve into one of two different forms, and which one you get depends on how you raise it. This is where evolution stops being automatic and starts being a decision.
The Helmut line is the clearest documented example: it can develop into either of two different creatures rather than following a single path. When a line branches, your choice is effectively locked in once the evolution happens, which makes the decision worth pausing over.
The golden Helmut branch uses Helmut (Mountain Woods Form), which does not join the ordinary Russet Highlands spawn pool at first. Complete the hidden Secret of the Golden Helmet encounter near First Sight Sanctum: pass the guard with a Cloak-capable twine form, take the helmet, and catch the Mountain Woods Helmut that appears. That capture permanently unlocks wild Mountain Woods Helmut and Rookey spawns, letting you catch spare Helmuts before committing one to a branch.
Practical guidance for branches:
- Check what each branch's element and role become. A branch that changes element changes every matchup calculation. That is usually the deciding factor, more than stat differences.
- Consider which branch you actually need. If your team is short on a role — healing, or something to break armoured targets — pick the branch that fills the gap rather than the one that looks stronger in isolation.
- Remember the twine payoff. Whichever branch you take is the form you can use for traversal and puzzles. A branch with a strong innate skill is worth more than a slightly higher stat total.
Evolution Requirements
The launch roster currently forms 29 lines with 54 individual evolution routes, including the weather-specific Nimbi route. The table separates the level gate, the element material and any branch-specific condition so you can see what actually blocks the Evolve button. A dash means that step has no element material in the current checklist.
If a branch asks for an elemental stone you do not have, a Flux Crystal can fill that stone slot. It does not erase the other gates: you still need the listed Aniimo level, boss or quest unlock, talent, personality, Potential threshold and any route-specific item. Open the final preview before confirming so you can see exactly which material the evolution will consume.

Melloblum, Inferlupa, Dazmand and Fulmintis use special branch materials rather than an ordinary stone alone. If the destination is missing from the evolution screen, put the required item in your inventory first. The branch can stay hidden until the item is present.
Evolution vs Resonance Training
These are two different systems and confusing them wastes effort. Both are part of raising an Aniimo, but they do different jobs.
Evolution changes which creature you have — it moves you along the line to a new form with a new stat baseline and a new skill set. It is a step change, and it happens at specific points.
Resonance training is how you build an Aniimo up. The official developer material names resonance star-up as a distinct system, and it is one of the game's core raising pillars alongside hatching, evolution and twining. Think of it as the ongoing investment you make in a creature, whereas evolution is the milestone.
The practical implication: do not neglect resonance while waiting for an evolution. The stats you build through resonance are part of the creature you carry forward, and an evolved Aniimo that was never invested in will underperform one that was.
Which Aniimo to Evolve First
Prioritise in this order:
- Your main damage dealer. The creature you twine into most often for combat. Evolving it raises your ceiling on every fight you take.
- A dual-element line. Evolving into a dual-element form changes your matchup coverage, which is worth more than a flat stat gain across a whole play session.
- Your traversal option. If a line's later stage has a better mobility ability, evolving it speeds up everything else you do. With no mounts in Aniimo, this compounds.
- A support creature with a role gap. If your team has no healer and a line evolves into a Heal role, that evolution fixes an actual weakness rather than adding power.
Deprioritise cosmetic preferences and creatures you only caught for a single puzzle. Every evolution costs resources, and spreading them across your whole roster leaves you with a team that is mediocre everywhere.
FAQ
How many evolution stages does Aniimo have?
Three: Lumin, Gamma and Nova. These are the stage names used in the game's own Aniimo index filter.
Do all Aniimo evolve?
Most do, but not all. Some creatures are caught in a single form, and some evolution lines are shorter, ending at Gamma rather than continuing to Nova.
Do all Aniimo pass through all three stages?
No. Some lines skip Gamma entirely and go from Lumin straight to Nova. Always check the specific line rather than assuming three steps.
What are the level requirements for evolution?
They range from level 12 for Emberpup → Flameruff and Skippy → Pranky to level 52 for Veilfloat → Luminelle in the current checklist. The full 54-route table above lists every level, element material and extra branch condition; check the creature's evolution screen before spending.
How do I evolve an Aniimo?
Open the main menu, go to Aniimo Management, select the creature, then use the cat-shaped Evolve icon just left of the Level Up button. That opens the evolution screen, where the requirements are listed; the Evolve button at the bottom of that screen confirms the change once they are all met.
Why can't I evolve Helion or Lunara?
Both starters are locked behind main-story progress. Levelling them or collecting materials will not unlock the Evolve button — you have to reach the story point first.
How do I evolve Celestis into Stellarys?
Raise the Celestis to Aniimo level 18, defeat Alpha Stellarys in the Forest of Falling Stars to unlock the evolution, then spend Night Stone x1. All of those conditions have to be satisfied before the button activates.
