Release2.3

Sixth Serenade is Kallen Kaslana's S-rank PSY-type Ice pistol user from v2.3. She stacks Raven Marks that Time Lock and blast groups of enemies, spends Nachtsicht on chained Combo ATKs, and her Ultimate turns her into Raven Form for a Combo ATK frenzy. She was a strong crowd-clearing Ice DPS, and her PRI-ARM Tranquil Rhapsody briefly brought her back (Marisa Impact), but she has no Astral Ring and is obsolete in 9.0: play her in older content and in the Elysian Realm, where she has been playable since v6.3.

Where to get her: War Treasury, Dorm Supply and Battle Pass (Marisa Impact). Every War Treasury battlesuit is outdated, so unlock her mainly for fun or for Elysian Realm first-clear crystals.

Teams

Recommended teams

Part 1 Ice supports

Sixth Serenade
Jade Knight
Sugary Starburst

Jade Knight and Sugary Starburst are the Part 1 Ice supports (Elemental Breach, buffs, Freeze Trauma). They carry her through older content, but Starchasm Nyx or any newer Ice DPS makes far better use of them. No Astral Ring here.

Classic elemental trio

Sixth Serenade
Phoenix
Flame Sakitama

A budget throwback: Phoenix raises the team's Elemental DMG and, from SS rank, makes enemies take up to 20% more Elemental DMG when she switches out; Flame Sakitama's Combo follow-ups and Ruinous Sakura make enemies take more Ice DMG. Old content only.

Guide

How to play

Nachtsicht and Combo ATK

  • She starts with 100 Nachtsicht (max 600). Basic ATK SEQ 2, 3 and 4 restore 40 Nachtsicht each.
  • Right after Basic ATK SEQ 4, tap [ATK] for a free Combo ATK (Gloomy Dawn): it deals Physical DMG, adds a Raven Mark and, with Sound of Peace, 3 × 120% ATK of bonus Ice DMG.
  • With at least 300 Nachtsicht, tap [ATK] after a Combo ATK (or hold [ATK] after SEQ 3) to spend 300 on another Combo ATK. Her QTE and Raven Blitz also lead into a free Combo ATK.

Raven Marks

  • Marks stack up to 3 on an enemy and go off after 5s: 1 stack = 100% ATK of Ice DMG, 2 stacks = 200% and a knock-up, 3 stacks = 2s Time Lock (the enemy cannot die), then 200% single-target + 100% AoE Ice DMG and 10 Rime Trauma.
  • Marks also corrode enemies, and she deals 40% more Total DMG to corroding enemies and 50% more to unshielded ones.

Ultimate: Night Carnival (125 SP)

  • Plants the Raven Cross (immobilizes enemies in a large area and applies an empowered 3-stack mark: 600% + 200% AoE Ice DMG), then a 12-hit shuttle attack.
  • Raven Form lasts 12s: she regains 150 Nachtsicht per second, so you can chain Combo ATKs non-stop; from SS rank she also gains +50% Elemental DMG.

Rotation

  1. Basic ATK to SEQ 4 → free Combo ATK, repeat while building Nachtsicht and SP.
  2. Ultimate as soon as you have 125 SP, then spam Combo ATKs during Raven Form.
  3. With Tranquil Rhapsody: hold the weapon active to enter Nightwalk (+300 Nachtsicht, +300 more when you pass through an enemy), release to pull enemies in, then tap [ATK] for a free Combo ATK.
  4. Use Ultimate Evasion for Raven Blitz (1 mark, 100–200 Nachtsicht, free Combo ATK; CD 15s, 11s with Sinner's Eye).

Her QTE triggers when an enemy's shield breaks. Her leader skill gives the team +24% Elemental DMG and 22% less Elemental DMG taken (32% / 26% at SS).

Strengths

  • Great crowd control for her era: Raven Marks Time Lock groups and the Raven Cross immobilizes a large area.
  • Raven Form lets her chain Combo ATKs non-stop for 12s.
  • Easy to unlock (War Treasury, Dorm Supply, Battle Pass) and playable in the Elysian Realm since v6.3.
  • Team-wide Elemental DMG leader skill.

Weaknesses

  • Obsolete in 9.0: no Astral Ring and far too little damage for Memorial Arena or Superstring Abyss.
  • Her Basic and Combo ATKs deal Physical DMG while her marks and Ultimate deal Ice DMG, which splits her buffs.
  • Her real power spike, Tranquil Rhapsody, is a Foundry PRI-ARM.
  • Weak Elysian Realm signets compared with recent battlesuits: play lower difficulties (Marisa Impact).
