Up to 3 of Aster's Stars can exist on the battlefield at the same time. If this limit is reached, summoning a new Star replaces the oldest Star with the fewest enemies in range.
Only 1 of Aster's own Stars can exist on each tile. When cast automatically, this skill prioritizes tiles with the most enemies that do not overlap with any of his other Stars.

Range: Global
After summoning 3 Stars, Aster permanently converts all his Stars into Black Holes and devours the Planets orbiting them.

When supercharged by Stellar Flare, Black Holes do not burn. Instead, each Black Hole drains 30% ATK and 30 Haste from every enemy within range. The ATK drained increases the damage of all Black Holes, while the Haste drained increases the frequency at which they deal continuous damage. These increases cannot exceed 60% and 60%, respectively. The cumulative ATK a single enemy can lose through this effect cannot exceed 60% of Aster's initial ATK.

Review
Aster is an S-Level Hypogean Mage who focuses on planetary abilities to summon Planets, Stars, and Black Holes. His main goal is to summon three Stars as quickly as possible so they can be converted to Black Holes. Other than his planetary abilities, his skill Darklight Pulse fires pulse beams that deal damage to hit enemies while gaining a shield equal to the total actual damage dealt by the beams. Additionally, the beams reduce the target’s shield value upon hit.
Upon casting his Ultimate Ability, Aster summons a Star on a tile that damages nearby enemies. He will also supercharge these Stars, briefly stunning enemies while also causing the Star to burn, dealing damage to enemies within the tile. He can summon up to three Stars; otherwise, he erases the oldest Star with the least enemies upon his next ultimate to replace it. Every time he summons a Star, his passive Gravitic Maw creates a Planet that orbits that Star. The Star targets the enemy with the lowest HP upon summon, but then deals damage to whatever enemies it collides with in its orbit. Upon a successful orbit, it deals damage to enemies on the Star it’s orbiting. While Gravitic Maw is active, he commands each Star or Black Hole on the field to pull the nearest enemy, dealing damage. Additionally, his Hero Focus ability allows each summoned Star to provide an ATK boost up to 3 Stars, and then he gains an additional ATK boost once the Stars convert into Black Holes.
Through his Mythic+ ability Starless Hollows, he permanently turns all Stars on the battlefield to Black Holes and devours any orbiting Planets. Once this is triggered, he will exclusively summon Black Holes on the field, dealing true damage to the enemies within one tile. Instead of being supercharged through his ult, the Black Holes will instead drain ATK and Haste from the enemies within range. The black hole then utilizes these drained stats, increasing the Black Hole's damage and frequency at which they deal continuous damage. At EX+15, while the Black Hole is supercharged, it deals additional true damage and devours defeated enemies in range to restore a third of Aster’s Energy. At Supreme+, he ascends into a higher dimension after converting the Black Holes and becomes permanently invincible until he is the last surviving hero on his team.
Story and AFK Stages - Aster can see various uses in these modes as he deals high damage and has high survivability.
Dream Realm - Due to his high survivability, he can be a good unit in some bosses during Pre-Endless, yet his Endless capabilities have yet to be seen.
PvP - With his crowd control, true damage, and invincibility capabilities, he proves to be an incredibly strong PVP unit.
Legendary+ increases his ATK per Star (up to 3 stars), with a bonus ATK buff after converting the Stars to Black Holes.
Mythic+ allows him to convert his Stars to Black Holes to deal true damage and absorb ATK and Haste.
EX+15 lets his Black Holes deal additional true damage and also allows them to devour defeated enemies to restore energy to Aster.
Supreme+ increases the pull range for Gravitic Maw while boosting his Energy recovery efficiency before converting his Stars. Once converted, he becomes permanently invincible until he is the last ally alive.
Aster is an incredibly powerful PVP unit, especially at high Paragon. He can control the battlefield and reduce enemy stats and shields, while remaining invincible in the backfield. However, his relevance in modes like Dream Realm is likely limited to early season. For accounts wishing to pull Aster, Mythic+ is an essential part of his kit to unlock True Damage capabilities through his Black Hole conversion while also reducing enemy stats. Additionally, EX+15 allows him to devour enemies to restore his energy, allowing for more ultimates cast throughout the battle. Supreme+ is also highly recommended so Aster can become invincible in the backfield, allowing him to control the battlefield uninterrupted.
High Energy Recovery.
