Fire UnF 2025 Preparation Guide

Next Unite and Fight is set for June 21st and will be Fire advantage. Let’s go over once again what you should work on in the meantime.

Weapons

To start, we’ll cover the weapons you should have available for this UnF.

General

This first section will cover weapons that are equally useful for Omega and Optimus.

General

SummonPriorityNotes
1 Sword of Valorblaze★★★★★
1 Scythe of Renunciation★★★★★
1 Scythe of Repudiation★★★★★Only required for Agni
1 Ultima Staff★★★★★
1 Ultima Claw (Fire)★★★★★
1 Altruism-Soul Staff★★★★★
1 Covenant-Ruin Fist★★★★★
Worldvexing Angelos★★★★★
1 Heat of The Sun★★★☆☆★★☆☆☆ as grid piece
★★★★★★ to recruit Alanaan
1 Norden Labrys★★★☆☆
Royal Deliverance★★★☆☆
1 Refrain of Blazing Vigor★★★☆☆
1 Draconic Harp★★★☆☆
1 Worldstorming Aetos★★☆☆☆
1 Kiss of The Devil★★☆☆☆MH option for Lucha
1 Ray of Zhuque Malus★☆☆☆☆Generally phased out but good if you lack the better cap up sources.

The most basic thing you should have leveled is your opus as that will be your mainstay for all grids. Level 200 is the baseline due to gaining the incredibly important 3rd skill slot. 230 is the most important transcendance level as it adds boostable damage amp to the opus. 250 is a minor upgrade to the skills but is still good to upgrade two if you can afford it.

When it comes to Ultima weapons, the most useful ones will be Ultima Staff and Ultima Claw. The former pairs with Manadiver as well as Alanaan. The latter is for Lucha setups. The claw should be Fire so it canbe mainhanded.

Next up, for World weapons, you’ll want Worldvexing Angelos as a strong slot for Manadiver teams. Worldstorming Aetos is an another decent pick for more skill damage from Manadiver and Zeta.

Moving onto celestial weapons, Altruism-Soul Staff and Covenant-Ruin Fist will be the main choices for the same reason as the Ultimas. Demolition-Tiger Axe will also be a pretty useful one especially with Wamdus.

As for NWF weapons, neither by themselves will be that useful. Kiss of The Devil is a MH option if you don’t want to make a fire ultima claw. Heat of The Sun won’t be used but still should be uncapped all the way for Alan’s FLB.

Draconic Harp and its upgrade Refrain of Blazing Vigor will both be great defensive investments for FA especially if you wish to tackle the higher NM fights or have weaker characters in general.

The Viking CCW Norden Labrys is also a strong investment for OTK. This is thanks to its 3rd skill casting Banahogg 2-hit superior Elemental damage to a foe (Damage cap: ~370,000 per hit).
Inflict DEF Lowered (25%, 180s).
If main or auxiliary weapon is a sabre: Boost to number of hits (2 times).
If main or auxiliary weapon is an axe: Also inflict status DEF Down (25%, 180s).
to activate at the end of a turn where 40 or more hits dealt. Banahogg is a very large skill damage nuke making it a lot easier to pull of an OTK.

Royal Deliverance is another strong CCW investment for 100% uptime on 100% debuff resistance and dispel cancel as well as dispelling on CA. This will make NM250 a ton easier if you lack the important characters that can dispel or prevent debuffs.

Gold Moon

Real score:

☆☆☆☆☆

As for Gold Moon weapons for Fire, there are two big ones.

Sky Piercer (Fire) is an excellent mainhand for Sumaibito setups thanks to giving the MC GTA and the extra bonus damage on the main character. While manadiver probably will be stronger at the higher levels, Sumaibito’s access to Tag Team All allies instantly perform a normal attack without using up a turn. for another round of teamwide normal attacks on the same turn as Alanaan’s 2 hit flurry will be make it a strong contender as well.

Higurashi is a CA focused weapon that will be BIS for any CA focused NM250 setups. As mainhand, it increases charge bar gain to all allies by 30%, provides 400k supp, and then on chainburst it grants the party debuff res up, dispel cancel, and 10% bar. Additionally, it adds 2 the count of any chainburst and will deal a 10 hit nuke on any 5 chain (3 CAs). On top of this, it has big Optimus glory. Generally though, I would wait to get this until more about NM250 is theorycrafted or even better until NM250 is out.

Colossus

To start, let us cover the weapons needed for Colossus grids.

Core

SummonPriorityNotes
4 Colossus Cane Ira★★★★★4 required for Extremity
2 Colossus Bomber Ira★★★★★
1 Sol Remnant★★★★★

Like most other elements at this point, the core of Omega grids are its M3 exalto weapon. In this case, that would be Colossus Cane Ira. Four of these will cover all your needs from OTK to burst to FA. 4 is also needed for Super Lucilius Keys for burst setups.

Colossus Bomber Ira is also highly reccomended for its skill cap up and supp. Particularly, it will be great for any FA setup and potentially NM250.

And the last super core piece to have is Sol Remnant. It provides 10% bonus damage on TAs. This does not stack with Falsehood but as a result frees you from needing Falsehood for that additional echo. It will be used in OTK, Burst, and FA so make sure its ULB.

Good to Have

SummonPriorityNotes
3 ATK Extinction Blade Mk II★★★☆☆
1-2 Nilakantha★★★☆☆
1-2 DEF Extinction Blade★★★☆☆
1 Colossus Buster Ira★★★☆☆
1-2 Sword of Pallas Militis★★★☆☆
1-3 Benbenet★★★☆☆1-2 with 1 Crimson Scale
0 with 2
1 Summer’s Mirage★★★☆☆
2 ATK, 2 DEF Al-Abad★★★☆☆DEF depends on how CA setups for NM250 shape up.
1-2 DEF Mortality Bow★★☆☆☆
1-2 Scimitar of Brahman★★☆☆☆
1 SPC Ushumgal★☆☆☆☆Good Relic Buster mainhand.

Outside the Exalto, the best mod in Fire is Extinction Blade Mk II. They will likely be good for any unboosted setups or Kag x Kag OTK. Another solid mod option is Nilakantha as it brings stamina. The HP mod on it is good as well for Wamdus setups or for FA.

Sword of Pallas Militis is another OTK weapon thanks to it providing 20% MA at max HP. Two of them is 40% TA which will be very helpful for EX+ setups.

Benbenet and their supp will be decent slots but are replaced easily by stronger weapons. You could use about 3 of them for OTK if you lack Crimson Scales. If you already have two Scales you won’t need it.

Al-Abad and Summer’s Mirage are for CA based OTK or CA setups for NM250.

For Defensive options, Extinction Blade, Colossus Buster Ira, Scimitar of Brahman, and Mortality Bow are all pretty solid slots. The bow provides 10% skill cap and 5% normal cap which makes it great for adding additional cap up.

On the topic of the bow, 2 ATK Mortality Bow Mk IIs are a safety investment. I don’t know if they would get used at this point since there really isn’t slots for them. But if you want to in case there is a use, they do pack a lot of value.

Premium Upgrades

SummonPriorityNotes
1-2 Crimson Scales★★★★★
1-2 Sennen Goji★★★★☆
0-1 Phoenix’s Torch★★★★☆

For premium upgrade options, Crimson Scale is your highest priority thanks to the unconditional 50k supp.. They are an excellent boost and its a highly reccomended to get one not just for the supp and cap up they provide but also for coming with Michael who’s backline 20% boost to Omega and Optimus weapon skills will come in handy.

Sennen Goji is fire’s best skill boost weapon providing both 100k skill supp as well as the Key of Sagacity effect of 30% skill cap and 10% skill amp. For any skill heavy setup, in another words most setups, it can offer a strong boost to damage output.

Phoenix’s Torch is an excellent mainhand for Manadiver setups providing an additional 6 hit skill nuke after normal attacks, raising Singed stacks, and healing and providing bar to allies.

Agni

Agni grids will likely be mostly stable until UnF. That said, things can always change.

Core

SummonPriorityNotes
3 Overriders★★★★★
2 Crimson Scales★★★★★
1 Phoenix’s Torch★★★★★
2 Lord of Flames★★★★☆
1-2 Sennen Goji★★★★☆

Overrider is both Fire’s exalto weapon as well as providing boostable bonus damage. This goes up to 50% and frees you from the Falsehood key. Crimson Scales offer 50k supp and 7% cap per party and are another major source of cap break.

Phoenix’s Torch is an excellent mainhand for Manadiver setups providing an additional 6 hit skill nuke after normal attacks, raising Singed stacks, and healing and providing bar to allies. It also comes with Big crit and heal cap to help reach 100% grid crit.

Sennen Goji is fire’s best skill boost weapon providing both 100k skill supp as well as the Key of Sagacity effect of 30% skill cap and 10% skill amp. For any skill heavy setup, in another words most setups, it can offer a strong boost to damage output.

Lord of Flames provides 7% special cap, 40% EX ATK, and 25% DEF per copy when at least 4 weapons of the same group are equipped. For certain burst setups, the additional cap up is great to push out more NA damage. Sennen Goji overall has lowered the importance of of having Lord of Flames for burst outside needing one copy for Percival. FA would like to have 2-3 available for the defense against the harder hitting fights..

Good to Have

SummonPriorityNotes
1 Dreadful Flamesword★★★☆☆
2 DEF Extinction Blade★★★☆☆
1-2 MA Ixaba★★☆☆☆
1 ATK Extinction Blade Mk II★★☆☆☆
0-1 Solomon’s Accelerator★★☆☆☆
1-2 Erichthonius★★☆☆☆
0-1 Twelfth Vertex of the Passels★★☆☆☆
0-1 Tiny Logger’s Axe★★☆☆☆For FA and NM250
1 Partly Powerful Popgun★★☆☆☆Keep two copies.
1 ATK Purifying Thunderbolt★★☆☆☆
0-1 Firestorm Scythe★★☆☆☆
0-1 Fist of Destruction★☆☆☆☆
0-1 Cloudblazer’s Broom★☆☆☆☆

Dreadful Flamesword and Ixaba are the main TA boost weapons for fire. Flamesword is an efficient slot for Wamdus setups packing medium HP to help her hit 60k HP, small stamina, medium ATK, and medium TA. Flamesword is best for boostable due to the TA being boostable. On the other hand, Ixaba is a strong damage mod slot thanks to its mix of normal ATK and stamina. It also provides 10% TA from MA awakening which will make it great in unboosted situations like OTK. Other alternative TA weapons are Solomon’s Accelerator which is great if you are missing Flamesword or Erichthonius which is farmable but the HP cut doesn’t pair well with Wamdus.

Twelfth Vertex of the Passels is the main alternative skill supp and cap weapon to Sennen Goji. Vertexes can replace them if you don’t have 2.

Fist of Destruction and Tiny Logger’s Axe are all crit weapons. Typically, going for crit is pretty low priority, but it can be useful for OTK or low button bursts. FoD has Big II crit making it the best as a crit slot. Tiny Logger’s Axe introduces stamina to the crit grid which makes it quite good.

Cloudblazer’s Broom, which is here not JUST cuz its Anna’s weapon, provides skill cap and HP which can be helpful for setups with Wamdus (Holiday).

Partly Powerful Popgun, Purifying Thunderbolt, Firestorm Scythe are Fire’s CA weapons. Popgun is the strongest CA slot thanks to providing big glory and special CA up. Purifying Thunderbolt is all around solid for both the CA cap up, ATK awakening, and Big crit. Firestorm Scythe is a boostable CA supp weapon but there probably won’t be space for it. Still I don’t want to ignore it completely just in case. Overall, I’m not rating the CA weapons highly simply because more NM250 theorycrafting needs to be done. They might all be highly used for it this year but for now just make sure you have the weapons and wait til more research is done before doing more.

Characters

Who to Level?

Below are bunch of characters that see use in various contents. If you have any of them, try to level them beforehand and don’t forget to invest in EMPs, earrings, rings, and artifacts for the characters you’ll use.

Burst

Full Auto

OTK

Who to Farm?

Next up, we’ll go over the Eternals and Evokers for the element that you should consider farming for.

Alanaan

Alanaan is Fire’s strongest buffer with one of the strongest single buttons in the game. His skill 4 Days of Redemption provides 1 turn 2 hit flurry as well as 4 turns of 100/20 crit, 100% TA and 30% TA to the party. This is essential to fire bursting right now and will be widely used through UnF. The two drawbacks for this is that he needs to be swapped into to his skill 4 and it also inflicts shorted to the party. This means you’ll need clarity if you want Manadiver’s nukes.

He does fall off for FA where his skill 4 can’t abused as much, but he’ll still be used up through NM150 as its easy enough to burst down the boss within four turns between his buffs and Percival’s teamwide instant attack.

Fraux

Fraux is an FA based healer and skill damage dealer. She has a double dispel via her skill 1 Crimson Nightmare 400%-500% Fire damage to a foe (Damage cap: ~480,000).
Inflict Nightmare Temptation 2 (Accuracy: 200%, 2T).
(When Solid Fortitude is in effect: Also inflict Nightmare Scarlet 2 (10% of damage dealt Damage cap: None, Accuracy: 200%, 2T) and remove 1 buff.)
and her skill 3 Indominus 400%-500% Fire damage to a foe (Damage cap: ~480,000).
Gain ATK Boosted (Stackable / Can’t be removed) (10% (60% Max), Multiplier: Unique Stackable) and
DEF Boosted (Stackable / Can’t be removed) (10% (60% Max)).
Restore all allies’ HP based on damage dealt (Healing cap: 2000) and remove 1 debuff.
double clears, heals a ton, and inflicts stackables. Like Alan, you will want her FLB with skill 4. Her skill 4 Splendor willl autocast her skill 3 on normal attacks for a ton of healing each turn. She will likely be quite helpful for NM200 and NM250 FA.

Tien

Tien is primarily a bounty bot with some strong output for FA bursting. She can quickly cap bounty and reach high overbounty levels for most FA setups making her great for going for Celestial drops. She deals multiple hit hit count skill nukes that do lots of damage and her GTA, bonus damage, and assassin are all quite nice. She’s not going to outperfom the strongest characters, but for a farmable unit she’s all around excellent for either NM90 or NM100/NM150.

What to Suptix?

In this section, we will go over the Special Suprise Draw Set that will occur before UnF to discuss any characters or summons that may be useful.

Medium Priority

Characters that fill some strong niches.

Ragazzo

Ragazzo is an excellent short term burst character packing GTA and auto nukes as well dispels, double strike, and 100k supp on his skills. He is also particurly useful because he deals lots of damage for two turns before dying and swapping in someone else. This is an easy way to bring in an Evoker in FA without needing Yatima to call death or to bringing an off element sacc. Instead you have a character that deals a lot of damage very quickly and leaving once his job is done.

Clarisse

Clarisse’s FLB has turned her into an excellent support for full auto Manadiver setups thanks to her strong skill damage buffs for MC as well as additional skill damage she brings. She also good debuffs, frequent delays, and a dispel that upgrades to double dispel when her stacks are maxed. Her main drawback is 5 dispels need to be cast before she’s becomes a strong slot. Thus she is best used for longer fights and paired with someone like Ragazzo or Fraux who can provide quick dispels.

Low Priority

Good characters that may be replacements for stronger characters or fill too niche a niche that you could work around for not having them.

Icarus

Icarus is a character that wants to be swapped in order to quickly reach 5 crests. Once he does, he’ll have passive 30% normal ATK, 100% DEF, GDA, 10k supp, and 20% normal amp and can use his skill 3 Primal Sword Deimos Gain Primal Sword Deimos (3T).
(Can only be used when Icarus has 5 Hellfire Crest.)
which gives him 3 turns of double strike and 90% bonus damage. Last UnF, he was apart of the fastest NM200 setups due to the great synergy it that has with Alan. Additionally, he is a great FA swap in from Ragazzo if you happen to not have Alan or Fraux FLB.

Sato

Sato is a CA focused character with quite a fair bit to offer. Her Ninja Art stacks increase whenever she doesn’t take a damage in a turn. This can raise pretty fast due to her dodge all on CA. After that reaches its max at level 5, she will autocast her skill 1 Brown Sugar Blast when she doesn’t take damage in a turn. The skill 1 comes with a dispel which will be helpful against NM250. Additionally, once Singed stacks reach 7 she will start casting her skill 1 on CA for more dispels. She also offers a 3/6 turn uptime 10% uplifted as well as a 10 hit skill nuke on 4 chain. In FA, she can’t use her skill 3 Hidden Ninja Art which does hold her back. However if manual setups do focus on CA teams, it does offer some useful choises of utility like debuff clear, insant charge + CA reactivation, or wind cut.

Elmott

Elmott (SSR) is a good OTK and FA character thanks to him autocasting his skill 1 Searing Scorcher 700% Fire damage to a foe (Damage cap: ~730,000).Inflict Burned (5000, 180s) and remove 1 buff.(When Elmott has 10 or more buffs: Activates twice.) on enemy special. WIth 10 buffs, this becomes a very hard hitting 2 hit nuke that double dispels. This makes him both great for pushing tons of damage in OTK as well as quickly shredding buffs in any buff heavy fight.

Satyr

Satyr is a very strong tank providing some with frequent substitutes, teamwide heals and debuff duration cut, and teamwide dodge all. She will definitely be a handy option for FA if the higher difficulties apply a lot of annoying debuffs.

Anderson

Anderson serves as a solid mix of a offensive and defensive unit. He deals a skill nuke on normal attacks and can also perform an instant attack if needed. On the defensive front, he packs a sub all and dispels on CA. As a result, he can be a useful option for OTK, burst, or FA. He’s not gonna be the best at anything but he’s gonna be the character that can do a bit of whatever you need. So if you really need a lot of slots filled he’s a good consideration.

Anna

I am legally obligated to mention Anna where ever possible even if she is very very low priority.

Anna (SSR) comes with fire’s only one turn assassin. Despite this, she doesn’t offer much offensively due to the lack of personal attack mods, echoes, TA, or other forms of cap break. Still, can be a sub damage dealer if you lack the stronger options.

She also provides 1% skill cap per Singed stack making her a solid backline option for Percy setups.

Summons

As always, summons are always a great option. The usual suspects of the echo summon Red Hare, the 6 Dragon Optimus sub aura summon Wilnas or the Optimus main summon Agni] are all great to pick up if needed.

What to Spark?

For this section, we’ll go over characters found in either Flash Gala or Legend Festival. This won’t go over any 3% banners because I do not trust them. Additionally, this won’t list characters who solely exist for their weapons.

Percival (Grand)

The highest priority spark is by far Percival (Grand). He is an incredibly powerful burst enabler thanks to his skill 3 Koenig Dekret 900% Fire damage to all foes (Damage cap: ~1,020,000).
All Fire allies gain Fire ATK Up (100%, 1T) and Bonus Fire DMG (1 time) (30%, 1T).
All Fire allies instantly perform a normal attack without using up a turn.
(Consumes King’s Blaze after activation.)
providing instant teamwide normal attacks like tag team paired with 30% echoes and 100% fire attack. He will be used at all levels.

Zeta (Grand)

Zeta (Grand) is a powerful sustained damage dealer packing 100% TA, 50% bonus damage, stackables, and dispel on normal attacks via her skill 1 Zeta (Grand) on an at worst 5/8 uptime. The uptime is usually closer to 100% though since she gains a 1 turn skill CD reduction every turn she’s at at least 100% charge. She also deals a skill nuke after every 3 ally TAs.

When it comes to burst setups, she is generally replaced by Wamdus (Holiday), but for sustained damage output and FA she is a lot better. The dispel on normal attacks in particular makes her incredibly useful for FA.

Michael

Michael provides a 20% boost to Omega and Optimus skills that takes effect even from the backline. This is particularly useful for activating Super Faa keys. She won’t be used really from the frontline so she’s a lower priority on that front.

Also her weapon Crimson Scale is fire’s Pact weapon coming with with 50k supp, 7% cap up, and axe voltage. There is no reason to not slot one if you get it.

Yuel

Yuel (Grand)

Fenie

Fenie is an excllent support unit providing some strong buffs to the team via her skill 1, teamwide bonus damage on CA, and heals, 2 turn debuff duration cut, and dispel on her skill 2. Her skill 2 auto activates whenever an ally takes big damage or is in red health. Her main drawback is that she needs to die once before she can reach her full potential making her not good for shorter fights. But for something like NM250 where she has time to die she’ll liklely be very good.

Classes

The following are the most likely classes to be used during UnF. Level them ahead of time, give them EMPs, and make sure to unlock their skills.

General

Full Auto

OTK

Artifacts

Artifacts are another system of character progression offer them additional stats or abilities. They can be equipped to any character who shares the element and proficiency of the artifact. When farming for a specific element drop, farm raids of the element. The artifact which drops has a 50% chance of being the element of the raid its dropped from.

Typically the most useful artifacts are those which provide NA cap, NA supp, damage amp, skill cap, or skill supp. Any source of additional cap break can make a major difference. Typically the NA cap or supp will take priority, but some characters may prefer skill cap.

The other major artifact type are TA artifacts. They will be invaluable for OTK to reach 100% TA on all characters and strong for some burst setups.

Beyond these, other stats may be useful for certain characters. Like characters with dodge mechanics would like dodge rate up boosts.

The max HP up for 70% def down artifact is also one to keep an eye out for. This artifact makes killing off units a lot easier which has plenty of tactical use even in FA.

Manatura

Another thing to farm for are the various Manatura that might see use.

The main three are from left to right the Leviathan Mino, the Ouroboros Mino, and the Dark Rapture Simulacrum. There are the primary three for most uses with Manadiver. All three use the same mechanic of dealing skill damage on normal attacks when MC has at least 1 crest at the cost of 30% charge bar.

Leviathan is the most basic and easiest to obtain especially since it can be traded for. It deals a 6 hit skill damage instance. And it also inflicts a debuff called Submerged with is used by the support passive to give MC 10% bonus damage.

Ouroboros is a very strong upgrade thanks to its 6 hit nuke hitting harder and support passive that provides 30k teamwide supplemental damage with an additional 5k supp per crest. The main drawback is the way to obtain it is from the Alchemy Lab where it costs a hefty 30k points. This cost is pretty significant for anyone who hasn’t extensively bar farmed before.

Lastly, the Dark Rapture Simulacrum is a side grade to the Ouroboros one. It deals a single large skill damage instance that also inflicts amplified damage taken. And its support passive provides MC with 30% perp ATK, 25/25 DATA, 10% cap, and +10 hostlity to MC at the cost of 10% HP per turn. In many cases for burst setups, this can slightly edge out over Ouroboros, but for any FA setup that lasts a significant number of turns, the HP cost can often prove to much.

Unlike the others, the Agastia Simulacrum is a very specialized one focus on setups where the MC will charge attack. The support passive grants the MC 9% (90% max) CA damage, and 3% (30%) max CA cap per buff on MC. And when MC has 12 or more buffs, it deals a massive 10 hit skill damage nuke that can easily deal over 9m damage in OTK setups. Combine this from the skill damage it inflicts on attack for over 10m additional damage after CA.

Upcoming Changes

In general, the period ahead tends to be slow on changes. Still, its possible for some major impacts to occur.

Exo Ifrit Crucible

Exo Ifrit Crucible is likely to rerun soon. With it will bring a new Exo weapon. Exo weapons are typically strong mainhand that see UnF usage so it’s fair to assume the same will be true here.

New EX+

Some new EX+ raid was announced for the next UnF. What this actually entails and how useful it is will remain to be seen.

New Characters

Before UnF, there will be several banners introducing a bunch of a new characters. This time of year is pretty quiet overall as UnF is right before Summer begins. Halloween characters will rerun though none are really needed for Fire UnF. Still, its possible for a surprise character release or FLB to make an impact.
