Black Onslaught

Ragna, using his Astral Heat, "Black Onslaught", on Terumi.

Astral Heat (アストラルヒート Asutoraru Hīto) is a finishing attack in the BlazBlue series which can be performed on the "match point", with the victim being within a low HP threshold.

The conditions when an Astral Heat can be used are as follows:

  • Heat Gauge must be at 100%.
  • Opponent’s health points must be below 35%. — in Calamity Trigger, it’s below 20%.
  • It is the "match point". (in other words, you must be one round away from victory)
  • One Burst Icon is required. — Continuum Shift only
    • If a combo is started within the victim being within HP threshold, then it's possible to build up to 100% Heat if below that amount to combo into an Astral Heat.
    • However, you combo into the health threshold above 35/20% health, then the Astral Heat cannot be performed mid-combo regardless if all other conditions are met (victim must tech/return to neutral first).

Since Continuum Shift, when the character’s portrait in the HUD is shining, it is the signal that indicates the Astral Heat can be used.

In Cross Tag Battle, when both teams have one character left, it requires activation of Level 4 Resonance Blaze and 9 bars on the Skill Gauge.

As of the console version of Continuum Shift, by successfully beginning an Astral Heat, the game’s theme song’s chorus can be heard.

  • In the arcade version of Calamity Trigger, only three characters – Ragna the Bloodedge, Rachel Alucard and Nu-13 – can use an Astral Heat. In the console versions, other Astrals can be unlocked by beating Arcade Mode with specific characters other than the aforementioned three.
  • All Astral Heats despite being deemed as "Instant Kill" attacks, all have their own amount of damage they do that is at least above 25/30% of total HP, just enough to finish off the victim.
  • Canonically, only Ragna the Bloodedge and Jin Kisaragi have used their Astral Heats.
    • Ragna used Black Onslaught against Yuuki Terumi in Central Fiction, and Jin used Rengoku Hyouha (Arctic Dungeon) against Bang Shishigami and TenjoAmanohokosaka during the Ikaruga Civil War, and he used it against Azrael in Central Fiction.
