Chrono Navi
Ai Hyperion Λ
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.

Stat targets
- Stigmata affixes: SP regen and SP cost reduction (Marisa Impact)
- Reach SS rank: it unlocks the 12 SP team refill and +40% team Fire DMG
- Always turn Aimer-γ Cutter into Aimer-Λ Domain with the Ultimate before swapping out
Talent priority
Where to get her: Asterite Shop and Open World tasks (Marisa Impact). Rudder in Dream and Idol Transformation were sold in the v8.4 battle pass Reserve Works and added to the Exchange House in v8.9 (official notes).
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.
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.
Notable dupes · Rank
Unlocks her leader upgrade (+30% team Fire DMG), High Performance Mode (team Total DMG after her Ultimate), System Filling and 4 SP + 200 HP per knocked-back chakram.
Micro Generator: knocking back the middle chakram restores 12 SP to the team, and turning it into Aimer-Λ Domain gives the team +40% Fire DMG. Also +10% Fire DMG per chakram (3 stacks).
+20% Total DMG for herself after knocking back the middle chakram.
