  Stellar FlareUltimate

  600 Energy

  Aster consumes 600 Energy to target 1 tile, summoning a Star to deal 360% ATK damage to enemies within 1 tile. He then supercharges all of his Stars, causing each Star to deal 240% ATK damage to enemies within 1 tile and stun them for 2s. Supercharged Stars burn for 6s, dealing 36% ATK damage per second to enemies within 1 tile. 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.

  • Lv 51Increases the damage dealt when a Star is supercharged to 270% ATK, and its burn damage to 42% ATK per second.
  • Lv 111Increases the damage dealt when a Star is supercharged to 300% ATK, and its burn damage to 48% ATK per second.

Void Nebula

Aster's Exclusive Weapon, skill Starless Hollows, up to EX +29

Passive. After summoning 3 Stars, Aster permanently converts all his Stars into Black Holes and devours the Planets orbiting them. From then on, Stars summoned through Stellar Flare are created directly as Black Holes. Initially, each Black Hole deals 30% ATK true damage plus extra true damage equal to 2% of the target's max HP to enemies within 1 tile every second. The total damage cannot exceed 60% ATK. 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.

• EX +5Increases the true damage dealt by Black Holes to enemies within range to 60% ATK plus 4% of the target's max HP. The total damage cannot exceed 120% ATK.
• EX +10Increases the true damage dealt by Black Holes to enemies within range to 90% ATK plus 6% of the target's max HP. The total damage cannot exceed 180% ATK.
• EX +15When a Black Hole is supercharged by Stellar Flare, it deals 180% ATK extra true damage to enemies within range. When an enemy hero is defeated within a Black Hole's range, that Black Hole devours them and restores 333 Energy to Aster.
• EX +27Rivalry Skill: Mage: In Rivalry Mode, casting an Ultimate increases damage dealt by 8% for the next 8s. Unstackable. The first Ultimate cast also permanently increases Energy recovery from attacking by 8%.
