“Ascension is the method by which you extend the limits of an Astromon's ability. Let's take Birdies as an example. At some point, you will find Beaker can no longer grow any stronger. When that time comes, you will need mystic stones called "starstones" to help him/her overcome his/her limits and continue progressing. That is what ascension is. You are still gaining experience, so you may not feel the need now, but ascension will be crucial if you wish to reach certain heights. You can obtain Starstones from the Starstone Dungeon. You will also need other stones infused with elemental energy, which can be found in Elemental Dungeons. Each dungeon is guarded by an overlord who is there to test you, and whom you must defeat to obtain the stones they guard. It is a good way to test your limits. Stocking up on starstones, and their elemental cousins, will be to your benefit as you progress.”
— Zephyros
Astromon Grades[]
All Astromons have a grade ranging from 1 to 6, indicated by the number of stars () they have. Astromons begin at different grades, but all can be ascended up to grade 6. An Astromon's grade determines its max level. This starting level is commonly referred as the Nat-level (abbreviated from "Natural level") of Astromon so for example Fire Miho is a Nat3, because Fire Miho naturally exists as a three-star Astromon.
Ascension[]
You can ascend Astromons to higher grades, increasing their max level. Additionally, when ascending an Astromon to 3 and 5
, they will learn passive skills that bolster their basic and active skills, respectively. However, take note that ascending an Astromon will reset its level to 1.
Requirements[]
To perform an ascension, the Astromon must be fully leveled up, and you must have enough Starstones and Elemental Stones. Starstones can be obtained from the Starstone Dungeon, and Elemental Stones from their respective Elemental Dungeon. The shady shop sells some too.
The table below illustrates the resources required to ascend an Astromon to the next grade.

Stone Fusion and Division[]
Players can convert low grade stones to higher grade stones through Stone fusion and break down higher grades stones into lower grade ones through Stone Division. This process requires gold. Stone fusion and division are unlocked after clearing stage 15 of Star Sanctuary on Hard.
Stone fusion and division can be found by clicking on an Astromon > Ascension > Stone Fusion or Stone Division.
In order to fuse a stone, click on its lesser version and then click "Fuse". (e.g. for a <Mid> Lightstone you would click on the <Low> Lightstone icon). To divide a stone, click on its stronger version and click "Divide". The plus and minus signs can be used to adjust the number of fusions/divisions to perform, and the "Max" button will set the number to the maximum number possible with owned stones (capped at 100 fusions/divisions). On certain days of the week, the gold cost to perform stone fusion of a given type will be reduced.
Conversion Costs & Requirements
Notes[]
Equipped Gems, Gem slots, Awakening, Evolution and Variant status remain the same after an ascension.
Ascending to 3 will unlock a passive for your Normal Skill and Ascending to 5
will unlock a passive for your Active Skill. Both passives vary according to the Astromon and its element.
After an ascension completes, the Astromon's level will reset back to one, and its stats will temporarily decrease. However, its stat potential will be higher, for the same Astromon level, the higher the grade the higher the stats. Note that leveling will be harder with an higher grade (Check the Experience page for more details).
Enhancing[]
Once an Astromon is Ascended to 6, the Ascension button is replaced with Enhance.
Enhancing further increases an Astromon's stats by using Mystic Essence, which can be obtained by Releasing 3 or higher Astromons. The stat that is increased and the degree of the increase is chosen randomly. If one is not satisfied with the enhancement, it can be cancelled, though this will not refund Mystic Essense. Up to six different enhancements can be saved, each changing one of an Astromon's grade stars to a silver color. The cost of adding new enhancements increases each time.
Star | 1 | 2 | 3 | 4 | 5 | 6 |
---|---|---|---|---|---|---|
Cost | 100 | 150 | 200 | 300 | 400 | 500 |
The degree of increase (but not the stat itself) for any given enhancement can be rerolled at any time after saving it, for a cost of 250 Mystic Essence or x100. All saved stat values can be rerolled simultaneously for 200 Mystic Essence or
x80. All saved enhancements can be undone at a cost of
x100.
When enhancing, it is recommended to save the stats you want first, regardless of value, and reroll the value on the stats later if need be.
Super Ascension[]
After an Astromon is fully enhanced, they will become eligible for Super Ascension. Super Ascension turns all of an Astromon's grade stars red, grants them across-the-board stat increases, and teaches them an additional passive skill.

If Super Ascension is performed on the same Astromon a second time, the player will have the option to overwrite the Astromon's existing Super Ascension passive with the newly selected one, or retain the old one.
