Release4.2

Fallen Rosemary is Rita's S-rank QUA-type Lightning scythe user from v4.2. She charges Disir, enters Valfreyja Form, summons spirits that leave team-buffing Runes, and marks enemies with Stain of Trickery before releasing the Trickster with her Ultimate. She was a great Part 1 Lightning support, but she heavily needs Iris of Helheim and ranks, and with no Astral Ring she is now an outdated pick, mostly useful as a Quantum Collapse source and in the Elysian Realm.

Classic Lightning team (Herrscher of Thunder)

Herrscher of Thunder
Fallen Rosemary
Azure Empyrea

The historical 2020 Lightning core: Azure Empyrea triggers Fallen Rosemary's QTE, she lays her Runes and Ultimate, then Herrscher of Thunder comes in to deal damage. Outdated in 9.0, but still fine for older content.

Part 1 Lightning with Elemental Breach

Herrscher of Thunder
Fallen Rosemary
Herrscher of Truth

Herrscher of Truth is a Part 1 Fire and Lightning support with Elemental Breach and big buffs; with three different types, Fallen Rosemary's leader skill also adds Total DMG. Lunar Vow: Crimson Love has since replaced Herrscher of Thunder as the Part 1 Lightning DPS.

Guide

How to play

Disir and Valfreyja Form

  • Basic ATKs fill her Disir gauge. At 100 Disir, hold [ATK] for a Charged ATK (400% ATK of Lightning DMG) that starts Valfreyja Form for 20s.
  • In Valfreyja Form, Basic ATK SEQ 3 summons Garmr (Ulf Rune: enemies take 15% more Lightning DMG, are Weakened and deal 30% less damage), SEQ 4 summons Linnorm (Ormr Rune: lightning strikes every second), and her Evasion ATK summons Strix (Strix Rune: team +15% Lightning DMG and 0.5 SP/s).
  • God Eater: at 100 Disir, hold [ATK] for God Hunter; at 200 Disir, God Devourer creates Stain of Trickery (enemies inside take 18% more Lightning DMG for 20s). Both grant invincibility and gather enemies. From S1, every Charged ATK also gives the team +35% Elemental DMG for 20s.

Ultimate: Helvegr

  • For 100 SP (CD 20s), she frees the Trickster: 1,200% ATK of Lightning DMG, a 1s Global Time Fracture, Quantum Implosion on QUA-type enemies, and 500% ATK of bonus Lightning DMG for every Rune it devours.
  • With Iris of Helheim, her weapon active puts her straight into Valfreyja Form with all three Runes and a full Disir gauge, and her Ultimate pauses all timers.

As a support

  • She charges on standby: teammates' Combo and Charged ATKs restore 65 Disir and 12 SP for her (CD 5s). Her QTE triggers on airborne or ignited enemies and puts her in Valfreyja Form.
  • Loop (Marisa Impact): weapon active → Charged ATK → Ultimate → evade → Charged ATK. If SP is short, evade, attack until half the gauge is filled, then Charged ATK. Every so often, use a full-gauge Charged ATK to refresh Stain of Trickery, then swap back to your DPS.

Some of her buffs (Gorging Spirits, the Ultimate's Quantum Implosion) are not tied to Lightning, so Marisa Impact notes she can help any team that needs a Quantum Collapse.

Strengths

  • Stacks team buffs and debuffs: Runes, Stain of Trickery, +35% team Elemental DMG from S1.
  • Her Ultimate inflicts Quantum Implosion on QUA-type enemies, which some Fire and Ice teams can use too.
  • Charges Disir and SP on standby from her teammates' attacks.
  • Invincible God Eater casts, enemy gathering and Weaken make her safe to play.

Weaknesses

  • No Astral Ring: Part 2 supports have replaced her in Superstring Abyss and the Memorial Arena.
  • Heavily needs Iris of Helheim and ranks to be usable (Marisa Impact).
  • Holding buttons to chain her actions makes her feel sluggish.
  • Her main target, Herrscher of Thunder, is itself outdated.

Notable dupes · Rank

S1
Big upgrade

Gorging Spirits: her Charged ATKs give the team +35% Elemental DMG for 20s. This is her key support rank.

SS2
Solid upgrade

After her Ultimate, she restores 1 SP and 45 Disir per second for 10s: a much smoother loop.

SSS
Optional

The Trickster deals 30% more Total DMG while Stain of Trickery is present.
