Release4.0

Starlit Astrologos is Theresa's A-rank BIO-type Physical cross user from v4.0, the support who pioneered off-field mechanics: her team builds Hexagram stacks, and she casts her QTE and even her Ultimate from the background without ever taking the field. Her tornado gathers enemies and buffs team Physical DMG and Crit Rate. With no Astral Ring she is an outdated Part 1 Physical support today, but she is cheap and still handy for older content.

Guide

How to play

Hexagrams and off-field QTE

  • Whenever your team hits an enemy, it gains a Hexagram stack (1s CD), shared by the whole team; taking a hit removes one (3s CD). Teammates' Ultimates add 5 stacks (10s shared CD).
  • At 10 Hexagrams with a target in range, her QTE Battle Summit becomes available: 1,200% ATK of Physical DMG and +15% team Crit Rate for 15s, without switching her in. It consumes all Hexagrams.
  • If her Ultimate is ready when the QTE is cast, her avatar turns into her Ultimate button: tap it to cast the Ultimate from the background too.

Ultimate: Eight Formations

  • For 125 SP (CD 25s), she summons a tornado that gathers enemies and deals 20 hits of 100% ATK of Physical DMG. From S rank it gives the team +25% Physical DMG for 18s, and it always grants the team 20% damage reduction and Ignore Interrupt for 15s.
  • Zither's Lament stacks on top: its cross gives the team +15% Physical DMG (and slows enemies), every teammate's Ultimate and burst-mode attacks deal 15% more Physical DMG, and she gains 20% ATK Speed.

When she is on the field

  • Her Combo ATK has a Perfect Cast: release [ATK] when the golden circle flashes for 600% ATK, 10 bonus SP and stacking Total DMG buffs (S rank).
  • Basic ATK SEQ 3 heals every team member for 120 HP and gives them 4 SP (CD 6s); she also starts battles with 50 extra SP.
  • Her Ultimate Evasion triggers a 2s Global Time Fracture and leaves a formation that teammates can activate for another 2s Global Time Fracture.

Her leader skill gives teammates Crit Rate on Charged ATK hits and up to 30% Total DMG in a team of three different types.

Strengths

  • Supports without ever taking the field: QTE and Ultimate from the background.
  • Big team buffs for her rank: Physical DMG, Crit Rate, damage reduction and Ignore Interrupt.
  • Her tornado gathers enemies well.
  • Cheap: she comes from the Asterite Shop and the Open World, and her weapons from the Exchange Shop.

Weaknesses

  • No Astral Ring: Part 2 teams have moved on from her.
  • Her QTE needs 10 Hexagrams, and getting hit removes stacks.
  • Most of her buffs only apply to Physical DMG.
  • Marisa Impact advises unlocking Valkyrie Blastmetal and the other Elysian Realm A-ranks first.
