Stellarys is the payoff at the end of a very short line. The Celestis family has only two recorded stages in Aniimo, so the little star-headed flier you catch early in Breezy Plains jumps straight to its final Nova-stage form with no middle step in between. The catch is that the evolution does not simply unlock by leveling: you have to find and beat the Alpha version of the creature you are trying to make first.
Quick answer: Raise a Celestis to Aniimo level 18, defeat Alpha Stellarys to unlock the evolution, then spend Night Stone x1 to turn it into Stellarys.
Celestis evolution requirements in Aniimo
Three conditions gate the change, and all of them have to be satisfied at the same time before the evolve button will do anything.
- The Celestis you want to evolve must reach Aniimo level 18.
- You must defeat an Alpha Stellarys to unlock the evolution.
- The evolution itself costs Night Stone x1.
Beating Alpha Stellarys only opens the evolution. Each Celestis you evolve still has to be level 18 itself and costs its own Night Stone.
Where to find Celestis
Celestis is a Dark-element DPS with a Lumin-stage body that is 0.9 meters tall and weighs 6 kilograms. It spawns across four zones in the Breezy Plains region, and each zone holds a different level band, which matters a lot if you want a head start on that level 18 requirement.
| Habitat | Level range |
|---|---|
| Nimbus Fields | 5–15 |
| Forest of Falling Stars | 20–25 |
| The Argent Strait | 28–32 |
| Echoback Landing | 36–40 |
Catching one in the Forest of Falling Stars or higher skips most of the grind, since those spawns already sit at or above the level threshold. Nimbus Fields is the easiest place to farm them early, but a level 5 Celestis needs real investment before it can evolve.
How to evolve Celestis into Stellarys
How to confirm the evolution worked
After the animation plays, the creature’s Aniilog entry moves from No. 5 to No. 6 and its stage changes from Lumin to Nova. Its element level climbs from 1 to 3, it grows from 0.9 to 1.4 meters, and it picks up Comet Aureus in its skill list. If your Aniilog still shows the Celestis entry, the evolution did not go through.
Stellarys stats and skills after evolving
Every stat goes up, and the biggest jumps land on the numbers a DPS cares about. Attack and magic attack both climb by 19 points, which is what turns the little scavenger into a proper damage dealer.
| Stat | Celestis | Stellarys |
|---|---|---|
| HP | 81 | 95 |
| Attack | 106 | 125 |
| Magic attack | 106 | 125 |
| Defense | 58 | 68 |
| Magic defense | 58 | 69 |
| BP attack | 46 | 54 |
| EP regen | 80 | 94 |
The kit changes shape too. Celestis only has its basic Dark attack, Star Glide and Shooting Stars. The evolved form trades those for a longer list.
- ATK (Dark, power 6) — ranged magic basic attack.
- Shooting Star Glide (Dark, power 74) — a dash that drops stars; three hits on the same target speed up energy recovery, and after four seconds you can attack while moving.
- Starfall (Dark, power 40) — fires three homing stars, each hit stacking a damage boost up to 15 times.
- Shadow Magic (Dark) — an escape that breaks control effects, pulls you back from the target and leaves an untargetable clone behind to mimic your attacks.
- Comet Aureus (Dark, power 166) — the innate ultimate, on an 8-second cooldown, that drops a barrage of comets on one target.
Shadow Magic is a defensive tool first. The clone keeps pressure on a target while you reposition, and you can swap places with it, so treat it as your panic button rather than a damage cooldown.
Rainstorm Form and Prismana Stellarys
Two alternate forms exist alongside the basic one, and both share the exact same base stats, height and weight as standard Stellarys. What changes is the typing and the extra glide skill each one carries. The Rainstorm Form is Dark and Water at element level 3, and it is the version that uses Aquatic Glide, a Water-element dash that drains the target’s energy on every hit. The Prismana form is Dark and Ice at element level 4, and it is the only one with Chill Glide, an Ice dash that stacks an Ice debuff on whatever it hits. Neither glide appears on the basic form.
Rainstorm spawns lean on the weather. Stellarys born in the rainy season turn up more often on rainy days, since their skin needs constant moisture, so the Forest of Falling Stars during rain is where to look.
Dark element matchups for Stellarys
Because the whole line stays Dark, the damage math never changes when you evolve. Dark attacks deal 1.6x damage to Electric, Grass and Holy, and drop to 0.625x against Water and Wind. Everything else takes normal damage.
On the receiving end, Holy and Wind attacks both hit Dark for 1.6x, so a Stellarys parked in front of either one will not last long. The alternate forms help patch that around the edges — the Water glide gives Rainstorm a lever against Fire and Rock, while the Ice glide gives Prismana an answer to Electric and Water targets that the base Dark kit struggles with.
Stellarys has no further evolution beyond this point, so once the Night Stone is spent, the only things left to chase are the two alternate forms and whatever gear and levels you pile on top.
