Release5.5

Spina Astera is Rita's S-rank MECH-type Fire battlesuit, an elegant scythe DPS who inherited Dea Anchora's Astral Harness. She builds Astrum, enters Astral Harness and finishes with a huge Astral Flare: Erupt that gathers enemies. She has no Astral Ring and has been replaced by the farmable Miracle ☆ Magical Girl (Sirin); Marisa Impact lists no top score for her, so in v9.0 she is a collection and Elysian Realm pick.

Part 1 Fire (Sparkle)

Spina Astera

Herrscher of Truth

Thousand-Faced Maestro: Cameo!

Marisa Impact's Part 1 Fire template: Herrscher of Truth (the only Elemental Breach source for Part 1 Fire, and mandatory for Sparkle's Ultimate CD reduction) + Sparkle's big buffs. Spina Astera cannot use Sparkle's double-Ultimate trick, because she has no Astrum left after her Charged ATK.

Part 1 Fire (Chrono Navi)

Spina Astera

Herrscher of Truth

Chrono Navi

The cheaper alternative (Marisa Impact scores Chrono Navi at 74–88% in this slot, versus 100% for Sparkle): Herrscher of Truth for Elemental Breach, Chrono Navi for buffs, Ignite and SP.

Guide

How to play

Astrum and Astral Harness

Astrum regenerates by 80 per second in normal state (max 600); landing Basic ATK SEQ 4 restores 50 more, and her signature scythe refills 10 to 20 per second on standby.
At 600 Astrum, hold ATK for Astral Flare: Ignite: she enters Astral Harness (+40% Total DMG, 40% less DMG taken, better Ignore Interrupt) and unleashes a Void Vortex. Hold again for Combust, then Erupt, which drags enemies in over a large area, deals 1,300% ATK of Fire DMG and ends the Harness.
In Astral Harness, Basic ATKs add Blazar stacks (SEQ 5 gives 5, max 20), each adding 30% ATK to Erupt's thrust; her Ultimate gives full stacks.
Enemies inside the Starshine Circle take 20% more Fire DMG from her (an independent multiplier; 13% before S1).

Ultimate and evasion

Pisces: Alrescha (Ultimate, 100 SP): refills Astrum, activates Astral Harness, triggers Time-frozen Domain, inflicts 12 Ignite Trauma and leaves a Void Vortex EX for an immediate Erupt.
Ultimate Evasion grants 5 Blazar stacks in Astral Harness, and entering the field with less than full Astrum grants 200.

Marisa Impact's loop: Charged ATK → Charged ATK + Weapon → full Basic ATK sequence → Charged ATK. When the Ultimate is ready: Ultimate → full Basic ATK sequence → Charged ATK. With Sparkle she cannot double-Ultimate, because she has no Astrum left after the Charged ATK.

Strengths

Smooth, self-sufficient Fire DPS with strong enemy gathering on Erupt.
Astral Harness gives her 40% DMG reduction and Ignore Interrupt.
Her Ragna and Little Joys sets are both forgeable, and she is in the Dorm Supply and the Elysian Realm shop.

Weaknesses

Outdated: no Astral Ring and no top score in current content (Marisa Impact).
Replaced by Miracle ☆ Magical Girl, a farmable and more modern Fire DPS from the War Treasury.
Relies on her signature scythe for standby Astrum regeneration.
