Release6.2

Chrono Navi is Ai-chan's SP battlesuit: a MECH-type Fire chakram user who bats her Aimer chakrams back at enemies, applies heavy Ignite Trauma and buffs the whole team's Fire and Total DMG. She was the go-to Part 1 Fire support until Sparkle replaced her; today she is the free alternative in Part 1 Fire teams and one of the easiest ways for new players to apply Ignite when a stage demands it. She has no Astral Ring.

Teams

Recommended teams

Part 1 Fire, free support

Herrscher of Truth brings Elemental Breach and Chrono Navi fills Sparkle's slot. Marisa Impact measures about 74% of the Sparkle team's damage for Sirin, who benefits most from Sparkle's double Ultimate.

Part 1 Fire (Helical Contraption)

Vill-V cannot double-Ultimate with Sparkle (her Ultimate ends burst mode), so Chrono Navi loses less here: about 88% of the Sparkle team (Marisa Impact). The same trio works for Dea Anchora.

Guide

How to play

Parrying chakrams

  • With a chakram equipped, her weapon skill throws an Aimer-α chakram that flies back to her; hit it with Basic ATK to knock it back at enemies (up to 3 times). Every knock-back restores 100 Λ Power.
  • At 300 Λ Power, hold ATK for her Charged ATK Aimer: Full Edges: a flurry that throws three Aimer-β chakrams. Knock them back with Basic ATK or the follow-up weapon skill Counterattack Order to deal Fire DMG and inflict Ignite Trauma.
  • The middle Aimer-β becomes Aimer-γ Cutter once knocked back: it stays in place for 12s, hits continuously and gathers enemies. Knocking it back restores 12 SP to the team (SS).

Ultimate: Λ Impact

  • 100 SP: a huge ground slam plus flaming ripples that inflict 18 Ignite Trauma. If Aimer-γ Cutter is on the field, it becomes Aimer-Λ Domain for 17s, gathering enemies and burning them even after she leaves.
  • From S rank, the Ultimate gives the team +10% Total DMG and +25% melee/ranged Total DMG for 20s; from SS rank, turning the Cutter into the Domain gives the team +40% Fire DMG.
  • On standby, she recovers SP whenever a teammate hits an ignited enemy (up to 24 SP).

QTE

  • Immediate Intervention triggers on Time Slow or Ignite: 3s of Time Fracture, full Λ Power and an instant Charged ATK chakram throw.

Marisa Impact's loop: weapon skill, spam ATK to parry the chakram until you have 3 stacks, Combo/Charged ATK, weapon to parry the chakrams, then Ultimate when you have the SP and swap out.

Strengths

  • Free to get (Asterite Shop and Open World tasks) and her gear is now in the Exchange House and the Foundry.
  • Strong team buffs: Fire DMG, Total DMG, and 12 SP for the team from SS rank.
  • Huge Ignite Trauma application and enemy gathering: a reliable counter to Ignite stages and bosses.
  • Still a valid Part 1 Fire support: about 88% of Sparkle's damage for most Fire DPS (Marisa Impact).

Weaknesses

  • Replaced by Sparkle (Thousand-Faced Maestro: Cameo!), who is faster and lets some DPS cast two Ultimates per rotation.
  • No Astral Ring: she has no place in current Part 2 teams.
  • As an SP battlesuit she needs S and SS ranks for her key team buffs.
  • Her chakram-parrying rotation takes practice.
