1. OVERVIEW
Chrono Navi is a new mecha-type fire SP valkyrie who excels at igniting enemies, with considerable SP regen and the ability to gather. Like every other SP valkyrie, she will be available during version 6.2 both through gacha and events.
While, as we will see later on, she is heavily dependant on her gears, it's also true that she is a significant and consistent buff to all fire teams, making her a worth-considering option to pull for.

While her self-SP regen is not on the same excellent level as Pardofelis and Eden, she is still a very valuable valkyrie.
Let's get into details and see if she is worth your crystals or not!

LEADER SKILL
All team members deal 10% more Fire DMG.
They also deal 9% more Total DMG to ignited enemies.

- At SSS-rank: All team members deal 30% more Fire DMG. They also deal 15% more Total DMG to ignited enemies.
PASSIVE
When Chrono Navi is on standby and a teammate damages an ignited enemy, Chrono Navi recovers 1 SP. CD: 0.2s. She can recover up to 24 SP this way. Switching her in resets this effect.
BASIC ATTACK
Slashes with the chakram nimbly.
SEQ 1: Deals 80% ATK of Fire DMG.
SEQ 2: Deals 90% ATK of Fire DMG.
SEQ 3: Kicks the chakram outwards to deal 60% + 10% x (3~7) ATK of Fire DMG.
SEQ 4: Slash upward repeatedly, dealing 50% + 60% + 70% ATK of Fire DMG.
SEQ 5: Slash downward vigorously, dealing 120% ATK of Fire DMG.
Igniting attacks deal 25% bonus Fire DMG.

WEAPON ACTIVE
With a chakram equipped, casting the weapon skill makes her throw an Aimer-α chakram unit that deals Fire DMG and later flies back. When her Basic ATK hits it on its way back, it will be knocked back at enemies.
It can be knocked back 3 times.
Every knock-back restores 100 Λ Power.
1st knock-back: Deals 10% ATK of Fire DMG per hit.
2nd knock-back: Deals 10% ATK of Fire DMG per hit.
3rd knock-back: Deals 10% ATK of Fire DMG per hit.


No Λ Power charges.

Λ Power full charges.
CHARGED ATTACK
When Λ Power reaches 300, hold [ATK] to exhaust Λ Power and cast Charged ATK, hitting enemies repeatedly and dealing 6 x 80% ATK of Fire DMG.
Chrono Navi then throws Aimer-β chakram units in three directions, which deal 40% ATK of Fire DMG along their paths and fly back to her.
In a period after casting Charged ATK, she can use weapon skill Counterattack Order.
Counterattack Order and Basic ATK can knock Aimer-β chakram units back at enemies to deal 25% ATK of Fire DMG and inflict 2 x 6 Ignite Trauma.
Counterattack Order deals 3 x 80% ATK of Fire DMG on direct hit.

After Charged ATK releases the third Aimer-β chakram unit, all enemies damaged by her within 5s take 22.5% more Fire DMG for 20s. Triggering it again resets the duration.
Skill Rank-up
At SSS-rank: After Charged ATK releases the third Aimer-β chakram unit, all enemies damaged by her within 5s take 35% more Fire DMG for 20s. Triggering it again resets the duration.
At SS-rank, unlock: For every Aimer chakram unit she knocks back, her Fire DMG increases by 10% for 10s. It can stack 3 times. Triggering it again resets the duration.
SP SKILL (base rank)
The middle Aimer-β chakram unit thrown by Charged ATK becomes Aimer-y Cutter once knocked bac**
** hit, Aimer-y Cutter stays in place to attack continuously for 12s, dealing 3 x 15% ATK of Fire DMG per second and gathering enemies.
ULTIMATE
SP cost: 100. CD: 20s.
Launch a powerful attack at the ground, which deals 1200% ATK of Fire DMG and sends out flaming ripples, which deals 800% ATK of Fire DMG to enemies within and inflicts 18 Ignite Trau***

**timate (Animation Only)
If present, Aimer-y Cutter will be enhanced into Aimer-Λ Domain.
It lasts 17s, deals 3 x 25% ATK of Fire DMG per second, inflicts 0.2 Ignite Trauma per hit, and continuously gathers enemies. When it disappears, it inflicts 2 Ignite Trauma on all enemies.

Ultimate (on enemy, fills Ignite Trau**)

**timate Duration Icon, it indicates how much time is left before Ultimate effects are over.
Just like Azure Empyrea's Ultimate Icon.
When Chrono Navi is on standby, Aimer-y Cutter and Aimer-Λ Domain deal an extra 20% ATK of Fire DMG per hit.
At S-rank, unlock:
- After casting Ultimate, all team members deal 10% more Total DMG, and melee and ranged attacks deal 25% more Total DMG for 20s. Triggering it again resets the duration.
- When the knocked-back middle Aimer-β chakram unit or Aimer-y Cutter becomes Aimer-Λ Domain during Ultimate, her igniting attacks deal 20% bonus Total DMG for 17s. Triggering it again resets the duration.
At SS-rank, unlock: Aimer-Λ Domain deals 20% more Total DMG per hit.
EVASION
Evasion attacks can also knock Aimer chakram units back. Can be performed twice in a row.
Evading forward: Deals 2x 65% ATK of Fire DMG.
Evading backward: Deals 80% ATK of Fire DMG.
Ultimate Evasion Skill: Causes Global Time Fracture for 3s. CD: 15s.
QTE
Triggered when an enemy is Time-Slowed or ignited. Tri***** 3s of Global Time Fracture, restores 300 Λ Power, and reduces switch CD to 4s.
She deals 8 x 120% ATK of Fire DMG and tri***** the Aimer-β chakram units throwing effect from Charged ATK at the cost of all Λ Power.

Time-Slowed QTE + Aimer-β

Ignite QTE + Aimer-β
That is all for Chrono Navi skills. Now, let's move onto next subject!![]()

3. RANK-UP AND SP SKILLS
Although Chrono Navi base rank is A-rank, it is a known thing that pretty much all SP valkyries need their rank-ups to be powerful options. And as you know, each primary rank-up (S, SS and SSS) will unlock an additional SP skill.
So, let's give it a look together.

As you can see, S-rank is already a valuable upgrade, as it boosts her SP regen by a huge amount. It will make a tremendous difference on fast runs, so go for it as soon as you can if not immediately.
At SS-rank, it starts to get costly, and without gacha it's going to take you some time. However, this skill is very important, not only for the huge Fire DMG buff it provides, but also for the Team SP Regen, which is an essential part of Chrono Navi's kit and one of the reasons that make her such a good support for Fire teams.
Meanwhile, SSS-rank doesn't have any strong utility in the long run, and it's also the most costly rank. You can take your time to get this one, however, you will definitely appreciate the skill when playing solo battles like Elysian Realm floors.

4 . SIGNATURE WEAPON

An artificial intelligence born in a Pseudotime Crystal.
Built into a general-purpose close to mid-range weapon
using futuristic materials and technologies.
It can bring out the maximum ouput of the Aimer System,

4.1 WEAPON COMPARISON
Now, let's give a look at other available gears and understand why, as we said at the start, Chrono Navi is heavily dependant on her gears. Let's start with weapons.
Once again, DO NOT PULL/FORGE A SPECIFIC WEAPON SOLELY FOR CHRONO NAVI.
Also, keep in mind that the numbers below don't represent the guaranteed damage. For each weapon, it's the highest number obtained out of 3 attempts, and there is still space for minor rotation mistakes.
I'm not a robot, after all... or maybe yes? ![]()

As you can see, while Rudder PRIarm classified first, Rudder In Dream was beaten by Purana Phantasma: Nighteye by a relatively significant amount, and by Purana Phantasma by a smaller amount. This is a pretty rare occurrence.
But what does it mean? Can you use Purana Phantasma: Nighteye and Purana Phantasma instead of Chrono Navi's signature weapon? Well, the answer would logically be yes.
However, keep this in mind: the only reason for you to use Purana PRIarm would be that you are not planning to pull for Chrono Navi's gear in version 6.2, which is understandable. Rudder PRIarm is still better, so if you are pulling for the weapon, you should upgrade it to PRIarm instantly and not use Purana PRIarm as an excuse or placeholder.
The difference is way too huge.
Meanwhile, when comparing the 5* weapon versions of both Rudder and Purana, we can say that yes, you can use the latest and save your crystals for upcoming patches (whether you plan to completely skip Chrono Navi's gear, or if the gacha gods only gift you Stigmata luck).
The other weapons are not really worth talking of.
Lost Conviction: ****ation and Lost Conviction have no benefits for Chrono Navi or for the team.
The same applies with Gilded, however, this is the only free chakram we have, and for some of you it can work as a placeholder, only for early and at most mid game.

5. SIGNATURE STIGMATA

Is this... Ai-chan's real power?!
AI: BLADE SUPREME (T)
Increases Fire DMG from weapon active and Basic ATK by 15%. When the host's Charged ATK or Ultimate hits, Fire DMG dealers on the team deal 25% more Total DMG for 20s. Triggering it again resets the duration. Cannot stack.
AI: KURIKARA (M)
Increases Fire DMG by 30% and Ignite Trauma by 25%. Reduces Total DMG received by 20%.
AI: PROJECT BUNNY (B)
Increases Total DMG by 15%. When weapon active or Ultimate hits, all team members deal 30% more Fire DMG for 20s (cannot stack). Triggering it again resets the duration.
2-PIECES SET EFFECT
When weapon skill hits, grants 1 stack of Spotlight that increases Fire DMG by 8%. Can only be triggered once per second and can stack 3 times. At max stacks, all team members deal 30% more Fire DMG to ignited enemies for 20s. Triggering it again resets the duration. Cannot stack.
3-PIECES SET EFFECT
Weapon active deals 15% more Fire DMG. When an ignited enemy is hit by a team member, it will receive 35% more Fire DMG for 5s. Triggering it again resets the duration.
Chrono Navi equip bonus: Igniting enemies will make them receive 20% more ignite DMG for 10s.
Here, your priorities will be T = B >> M.
While both 2-pieces effect and 3-pieces effect are indeed very good, if you get T, B and weapon, you will lose some consistent damage but you can choose to stop pulling and save for upcoming patches (especially if you are waiting for GLB anniversary).
But also keep in mind that next time her gear comes back, your guarantee counter will be reset.
So make your choice carefully, captains.
NOTE: 2-pieces is extremely important and easy to activate. All you need to do is following the damage test rotation I used, which means: entering on QTE with Chrono Navi to instantly get full Λ Power, then use her Special Weapon Active Aimer-β to get all 3 stacks of Spotlight (2-pieces effect), cast Ultimate and then switch out to continue the rotation.
Very simple, don't you think?

5.1 Stigmata Comparison
And now, time to compare various stigmatas to see if you can use anything cheap on her! (If you are here for that...run away)
I compared some of the most viable sets that match her kit and gameplay at least a bit.
Again, a reminder that these numbers are the best out of 3 runs, it doesn't mean they are globally the best number.
Keep minor mistakes/slower attacks in mind!

As we said beforehand, 2-pieces alone are good but you do lose a lot of damage.
Just by comparing the two best options, full Ai-chan set and Ai-chan TB Aslaug M, you can already see a difference of over one million worthy of damage. So, if you are going as far as to getting 3/4 of Chrono Navi's gear, you might as well go all out.
Moving to other options, Turgenev TB Mei M and Turgenev TB Aslaug M got almost the same score.
Ai-chan TB Mei M is also another option that came very close.
Ai-chan TM Irene B is another considerable option, and the first one including a craftable stigmata.
In this build, Newton B will also work. I chose to test Irene instead because she is accessible to everyone.
After this, the damage output drops further, so I don't really recommend running the last 3 sets shown, unless you really have nothing else to use (if you are an older player, why do you not have Turgenev... WHY
)
Before moving on, there is another set I'd like to talk of, which is the very common Jinshengtan TM Newton B.
Why did I not test it? Well, I personally find this set weaker than the other options. It's a very old set, only really used for fast MA kills, but Chrono Navi is not suitable for that. She doesn't have time stop on her Ultimate animation, and her knock-back chakram attacks do take some seconds.
You are free to try it for yourself, of course, since her Ultimate lasts over time, you might find some benefit in it... but I leave that to you, captains!

5.2 WHAT ABOUT MARGRAVE SET?
"Hey! You forgot Magrave! Bad tester, noob"
Worry not, I did not forget about this set. Instead, since it's a very particular situation, I wanted to talk about it in its own section.
So...let's give it a look!

What does Magrave set do? Margrave provides a lot of buffs, which is why I still believe this set can keep surviving in the game.
It provides self-Fire DMG and ATK speed, followed by Team buffs such as Elemental DMG buff, HP restoration, enemies Total DMG taken, and lastly, huge Total DMG buff from the 3-pieces set effect.
Does it mean the set is good and Chono Navi can use it? The answer is, indeed, yes! She can use it. And as a very sweet addition, it's a fully craftable set!
However, there are a few downsides we will have to talk about.
First of all, the two words that appear on every single buff Magrave provides: cannot stack.
Which means, if your other team member is Azure Empyrea, you will not want to use this set on both of them, because there is no benefit in doing so. It's almost the same as bringing one of them without stigmatas.
If, on the other hand, your other team member is, for example, Midnight Absinthe (Raven) or Reverist Calico (Pardofelis), you can consider using Margrave on Chrono Navi. It is a strong set, after all.
But at this point, we talk about the other downside.
To fully benefit from this set, and mainly of the 3-pieces set effect, you are required to spend a total of 125 SP in one go.
And this is not achievable for Chrono Navi, as her Ultimate only costs 100 SP.
However, this is just a decrease in the overall performance. It does not make the set a bad option.
Keep in mind both these downsides when you play. Magrave is usable, but more benefitting on its designed owner (Azure Empyrea), while Chrono Navi can use other options.

6. TEAM LINE-UP
Now, let's give a quick look at what Chrono Navi's team line-up(s) look like.

NOTE: Depending on the leader skill and stage you are playing, for example Abyss, you might want to run Chrono Navi as the leader instead of HoF.
While Chrono Navi is not viable in any other elemental team, she is not a picky support.
Any Fire DPS will be a good match for her. Herrscher of Flamescion and Spina Astera are the best ones in the game at the moment, and currently the only ones worth obtaining and building, that's why they are the only two Fire DPS characters to make an appearance in this guide.
For your other slot, there are three options:
- Azure Empyrea; she is the best valkyrie for this slot, providing Elemental Breach and various buffs. While she has indeed gotten old, she is still usable. And thanks to Chrono Navi, you will have an easier time farming SP for her.
- Reverist Calico (Pardofelis); let's say you don't own Azure Empyrea for different reasons, Pardo is the right replacement! She has proved herself to be an extremely viable support in all elemental teams, only leaving Lightning teams on the side when you already have both Fischl and Eden.
- Midnight Absinthe (Raven); as a second support option, she ranks last. Pardo is more benefitting in general. However, you can prefer using Raven on MHT-3B Nirvana boss. Raven is not a good option anymore, she had a lot of issues in her kit that have been fixed in Chrono Navi's kit. Which means, she has been replaced. But who am I to tell you not to play her?

7 . ELYSIAN REALM

NOTE: As the picture says, this is a short guide for Finality difficulty. On lower difficulties, mainly Abstinence, you can use other gear options we have shown above. Leeuwenhoek TB Thales M didn't exactly perform well for me, but you can try it out if you like pain.
SIGILS, SUPPORTS AND EGO SIGNETS: WHAT TO DO?
This is something you will have to change as you play. Chrono Navi's performance in Elysian Realm really depends on her Ego Signets and on the right Signets choices, so let's see how you should handle it.
For Sigils, you'll want to start with Veil of Tears and Because of You. You'll have to reroll the first floor door until you get Ego door.
If you want to try and make it faster, you can use Crystal Rose at the start instead. But that will mean you'll have less chances of getting Discipline doors after the first door.
When it comes to Support Valkyries, Azure Empyrea is a guaranteed pick. For the second one, I personally recommend starting with Vermillion Knight: Eclipse: she will help you deal damage to mobs when you still lack Signets and Cores.
You can switch her with Blood Rose on either Floor 6 shop or later on Floor 9/10, just do it before the second boss.
Now, let's get onto the Signets builds.
Always get Succession as your first Ego. It's very helpful damage-wise, and also provides SP regen for early floors.

On Floor 2, you can choose between Constant and Final Dream. While the first one is better to obtain first, it's also not guaranteed to appear. So instead of restarting your run, just settle for the latest.


After Floor 5, go to shop, use Because of You, and change it to a damage dealing Sigil. I chose Falling In Past Light because it's very easy to recharge thanks to Chrono Navi's frequent weapon active usage.
If you already got Discipline 2nd Core, you can also change Veil of Tears/Crystal Rose to Pseudo Miracle and focus on getting Helix Signets afterward. If the rng gods allow it, you should try and get Helix 2nd Core before Floor 9 shop (for example, by getting two Helix Signets from Floor 6 shop and one from Floor 8 boss... so yes, very rng based, but possible).
On Floor 7, it's very crucial that you clear the bonus challenge, so you won't have to worry about any other Ego door later on.
Here, you will want to pick what you previously missed between Constant and Final Dream, and as the last Signet you will have to pick Bladepiece.

Time Crystal is not bad, however, I find that the 40 stacks take way too long to charge, so it's not a Signet you will benefit from at the start of the floors.
Once you get both Discipline 2nd Core and Helix 2nd Core, and all the Ego Signets you need, you can focus on getting Reinforcement Cores. Let's talk about them a little.
REINFORCEMENT CORES
As we said, Discipline 2 and Helix 2 are a must-have. You can also try and get some enhanced Signets, mainly Elemental Breach from both of them.
Along with them, there are some good options you can aim for:
- Stars 2; you'll want to prioritise Red Paint, Black Paint and Yellow Paint. Grey and White can be good, but not worth sacrificing the other ones. You can get either Grey or White from Shop if you want.
- Bodhi 1; Chrono Navi has very high hit-counter, so she can easily trigger Bodhi's Core ability. Nonetheless, along with TDM and enemies damage taken, you'll definitely want at least the 25 bonus combo hits, and can take in consideration the 60 bonus combo hits when the combo is 0. They will both help you spam Bodhi's Core ability, but just the first is enough.
- Vicissitude 2; as I said in other guides, Hua is always good on anyone. Not only she provides lots of buffs, but with her Core, you'll also have an easier time surviving. Chrono Navi can still clear Elysian Realm without Vicissitude 2, but this one will also protect you from interruption when you are knocking back the chakram (and trust me, you get interrupted A LOT).
ADDITIONAL SIGNETS
For extra additions, either as Cores or spare Signets, you can aim to get Gold Signets for SP regen, Reverie Signets for general damage buffs, and lastly Decimation Signets (Core not recommended) for damage buff with Blood Rose support.
That is all for the "short" Elysian Realm guide.

8. CLOSING STATEMENTS
Chrono Navi is a very valuable Fire Support, that provides huge buffs to the team and self, SP regen, faster rotations and applies heavy Ignite Trauma on enemies. Her gears, like every other SP, will be available through a special 30-pulls-guarantee supply.
So, what are you going to do?
Does Chrono Navi intrigue you? Will you give up to the Cabbage Queen?
Or are you going to stay strong, keep on suffering on every Fire Weather, to save your crystals? It's only up to you, captains!
And now... see you on the next guide!
