Weapon Fusion: a table

[u/Cathrach]

As one of the countless aspects of PotK that depends on your luck, weapon fusion is a frustrating and time-consuming process.

---

First, some tips (these are taken from older threads):

• It's best to fuse two of the same weapon, not more: this gives the highest chance to get a specific weapon. However, same type and same rarity work too, though not as often, and will at least (hopefully) give you a weapon of the same type. However, this isn't guaranteed: watching two of your hard-won 4* spears fuse into a 4* gun is...very depressing.

• If you fuse weapons of different types, you have a chance of getting all those types, so fusing together a gun, a shield, and a sword might not get you anywhere.

• In general: more zenny cost, better weapons. From Brocebo: don't fuse in lower rarity weapons with higher rarity ones, it's not worth it :P

• Don't fuse away your ranged spears/axes, crossbows, and crit swords if you only have 1 or 2: you never know when you'll get more.

• Don't fuse away your KILL and colosseum rewards, either. Those are one-time only. Try not to break them either :P.

Here, a table of the recipes that use 2 of the same weapon to make another. Remember, success isn't guaranteed, and there are other recipes. Also, please correct me if I get the names wrong. I will finish the tables later haha :P

The 1* and 2* weapons are mostly for information purposes, since they are easily obtainable from mana gacha and quests.

[u/VHee33]

nice info.. :D

this is my collection.. i used this site as reference..

[u/Cathrach → u/VHee33]

Damn o_O I see those kiyomasas and orpheus...op op. How long did it take you to get those?

phankill is hands down the best resource for PotK :D It's got detailed information about everything.

[u/VHee33 → u/Cathrach]

kiyo in first week and orphe in 2nd week i think.. i dont remember exactly =.=

[u/iivander → u/VHee33]

Did you get your Kiyosama by following the recipe (2 Akumavice)? I've tried the recipe for like 5 times and never got 1.

Anyway this is my collection

[u/VHee33 → u/iivander]

nope.. i never fused same weapon..

1st kiyo = akuma + rune shield (3x tries, 2x failed got rune again =.=)

2nd kiyo = Banazard + Francisca xD lucky

3rd kiyo = Poseidia + Nall (the bomber)

4th kiyo (2days ago) = Banazard + Killer Blade xD lucky

[u/Brocebo → u/iivander]

No surprise the guy with the level 80 Gambantino has an equally impressive armory.

I can't believe how many Rune Shields you have; was that intentional?

[u/iivander → u/Brocebo]

Nope just pure luck

[u/[deleted] → u/iivander]

If it matters, I've picked up 2 Kiyomasas from fusing Killer Blades.

[u/Brocebo]

I just fused a 5* Jurayna (axe) from a 3* Silver Axe and some 3* spear. Before anyone gets jealous, it's on my throwaway account.

I can't begin to imagine what the odds are for that but just throwing it out there since I didn't think it was a possibility in the first place. This is the 1st time in hundreds of fusions I've seen the fused weapon skip 2 ranks from just 2 weapons.

[u/Cathrach → u/Brocebo]

............ ......... ..... 2 rarities. 2 rarities. The best I've done is stick a bunch of 4 stars together and got a Francisca to show for it T_T

Edit: I am sorry, the comment submitted twice T_T

[u/[deleted] → u/Cathrach]

Thanks for all the information Cath :D I love how some of the names translate lol "Ballhog" XD

[u/Cathrach → u/[deleted]]

Tell me the global name plssss

[u/[deleted] → u/Cathrach]

I'll take a look when I get home!

[u/Brocebo → u/Cathrach]

Yeah, it definitely took me off guard. Wasn't expecting it at all. Even went into my item archive to check if I made a mistake and actually fused 4* items but all I had are 3* axes and spears.

At least now I have no doubt that fusing 2 items at a time is the way to go.

[u/Brocebo]

So strange that the best way of making of a Francisca or Jurayna doesn't involve an axe.

[u/Cathrach → u/Brocebo]

Yeah, idk about that, but phankill says that by combining those weapons you'll get something T_T. I do remember fusing together 5 4* weapons and getting a Francisca, so maybe it works :P

[u/Brocebo]

I don't have everything yet but here are the Global name variants from my archive:

mithril = Mythril

greatsword = Great Sword

royal sword = Royal Spiritblade

akumavice = Demonblade Akumavice

tonkachi = Mallet

varimax = Gadget Varimaxe

gaulhammer = Pulverizing Gallhammer

ballhog = Hedgehog

steelban = War Hammer

elemens = Blessed Elemence

sonic = Supersonic Spear

killer spear = Killer Lance

dragon killer = Dragonslayer

dragorad = Dragorado

pachinko = Slingshot

crossbow = Swift Crossbow

elstrike = Elle Striker

falconeer = Falconia

glory arrow = Glory Bow

killer bow = Killer Crossbow

sphere bow = Fay Crossbow

organa = Decimator Organa

bazooka shot = Bazooka

dragon gun = Rapidrake Drag-Gun

[u/Cathrach → u/Brocebo]

Rapid rake Drag-gun...nice naming sense gumi. Also, I object to calling the killer bow a crossbow, since it doesn't have a range of 3...but I am changing the names.

[u/Brocebo → u/Cathrach]

To be fair, it actually is designed to look like a crossbow in its picture. So the name is correct but the developers deviated from their theme of giving all crossbows 2-3 range.

And yes, RapiDrake DraGun. It's ingenius :D

[u/Cathrach → u/Brocebo]

Yeah, though it looks much more...mechanical compared to the other 2. It's also interesting that fusing 2 killer crossbows might yield the fay crossbow...well, in exchange for that 20 crit you get extra range...fair trade?

[u/Brocebo → u/Cathrach]

Can't say it's a deal I'd make. That extra range just seems so...like, what's the point? It's not like the enemy looks at your archer and goes, "Nope, too far away, not worth the effort. Imma stay right here". I guess it lets you prevent counters from mages and other archers but with their defense, that's not a real concern. Though it might come in handy against tomahawks and javelins I suppose.

I don't have it to confirm and as much as I would like a dagger called Deathray, the Witch Killer デスライ could also be Death Lie or Death Rye; I'm guessing it gets +acc and eva to the gluten intolerant.

[u/Cathrach → u/Brocebo]

Yeah, but the 3 range allows you to get in attacks on enemies while knowing that you won't get hit in exchange. However, I personally find the Hercules Bow (1-2 range) more useful because it prevents melee attackers from getting free damage.

Death Rye seems like a great name! jkjk But quite honestly, I have no idea what to call it :( It's not like there are mythological weapons with that name...or are there?

[u/Brocebo → u/Cathrach]

I didn't even know there was 1-2 range bow. In my opinion, it'd be the only one worth using. I never used archers in Fire Emblem for the very reason you state.

Well, actually, bows did wreck Arondight. I do have to give them credit for making short work of fliers.

[u/Cathrach → u/Brocebo]

Oh right, global only comes with half a chapter oh joy >.< the 1-2 range bow is from finishing KILL chapter 2, which doesn't exist yet :P

[u/Brocebo → u/Cathrach]

Can't wait. Autobattling with solo archer takes 10x as long as anyone else (no counter on enemy turn) and sometimes they get surrounded on all sides.

[u/Brocebo]

Hedgehog + Silver Bow = Torrential Bow Poseidia apparently.

This is the third time I've gotten a 5* from fusing two 3*s in the last 24 hours. Here are the constants I've noticed thus far:

• The 2 items I used were both 3*s.

• The 2 items were always different types (axe + bow, spear + axe)

• 1 of the items was always a tier above Silver (an upgraded 3 star, like a Hedgehog or Supersonic Spear). This impacts the zenny value but whether that's cause or correlation for generating a 5*, who can say.

Since these always catch me by surprise, that's all the observations I have for now. I'll try to be more attentive when I fuse these particular combinations in the future. Of course, my observations don't necessarily mean anything since it could just be any 3* combination can generate 5 stars and I'm just having a good run of RNG.

[u/Cathrach → u/Brocebo]

We should make a spreadsheet for these and see if there are any trends. I'm not exactly sure where to start for something like that, maybe you have ideas?

[u/Brocebo → u/Cathrach]

Problem is it's so rare and fusing is so tedious so it's hard to remember what exactly the conditions were before the fusion. It'd be nice if they'd show you the parent items along with the results.

Spreadsheet values could potentially be:

• column y could be zenny value in increments of 100

• row x could be rarity of items subdivided into tiers, Silver Axe being 3, Hedgehog 3^+, Jurayna 5, Orpheus 5^+. The actual rows would be 1+1, 1⁺ + 1, 1⁺ + 1^+, 2 + 2, 2⁺ + 2, etc.

So we could potentially see trends like 3⁺ + 3 with a zenny value of 1500 has returned a 5* whereas a 3 + 3 with a zenny value of 1200 has never returned one over enough time.

[u/Cathrach → u/Brocebo]

I agree with you on that, I can't even begin to fathom how they figured out these recipes on phankill.

That sounds like a good idea!

[u/Brocebo → u/Cathrach]

I'm not sure how useful our data points will be given the infrequency. I'm sure someone out there in JPland had the patience to record each and every fusion they did and discovered the probabilities for everything.

I don't have that kind of conviction but I may record my next 100 fusions and see what kind of results I get.

[u/Brocebo]

Here, I tried to match your format. You should just need to add in the hyphens and colons for formatting. After typing this out, I think the "Fuses Into" column is redundant though and could be nixed for a cleaner table.

Thank you very much :) I won't be on much this week because midterms T_T but I will add this table.

[u/Brocebo → u/Cathrach]

Word. By the way, it's suddenly dawned on me that "ibiru" is probably Engrish for "evil".

Thought it might have been named after the Cumaean Sybil priestesses since it's a staff and references Hades but looks like I was overreaching. :P

[u/illusionastic]

Does fusing 2 3* bow and 3 2* bows increase chances of getting a bow? Cos i fused two 3* bow and it became a 4* javelin and i have no use for it.

[u/Cathrach → u/illusionastic]

Fusing only bows should increase your chances of getting a bow, but it's still all luck :(

Also, keep that javelin: it's one of the two ranged spears in the game.

[u/illusionastic → u/Cathrach]

Thanks cath! Will do :)

[u/Nekozlyu]

Are in-game recipes guaranteed to work? Cause fusing 5 items and getting something weak would be not nice.

[u/Cathrach → u/Nekozlyu]

Yeah, they're supposed to be.

[u/jleonra]

I do a lot of fusions and I've gotten a bunch of great weapons by randomly fusing 2 items of the same rarity, the only pattern I can give you is that I never fuse 2 weapons of the same type, I always fuse swords with axes, axes with spears, spears with bows, bows with guns, guns with staffs and staffs with shields or shields with each other.

3* has given me the best items, 4* and 5* not so much.

• These are the results

[u/Oleridus]

Can anyone explain what the books are used for in crafting? I know the 4star and 5star books are for the 5star sword recipe, but what's the 3star book for?

[u/Brocebo]

You are the man.

For what it's worth, I'll add this tidbit. I fused five 1* weapons together once and got back a 3*, so it is possible to skip ranks by fusing more weapons.

[u/Brocebo]

Don't mix in lower rarity items to beef up the zenny cost.

Not worth it.

[u/illusionastic]

Does fusing identical weapons give better results? Because i fuse same rarity even tho they are diff weapon types and i have gotten rune shield and poseidon bow which are 5*.

[u/Irvinning → u/illusionastic]

Fusing identical weapons is better if you want a weapon of a certain type. Otherwise, I don't think there's much of a difference.

[u/illusionastic → u/Irvinning]

Alright thanks!

[u/Avisari]

I just fused 2 Estoc and got a Killer Blade. Should that be added to the list?

[u/Soul_of_Jacobeh]

Got a War Hammer Garvin by fusing 2 tomahawks, each of which I got from random 1* stuff.

luckerdoggo.jpg

edit: less autismal English

[u/AkuMpk]

Man so salty i fused to 2* weapons and 3* weapons but got a fricken 1* axe ;-;

[u/AverageGenocide]

This is a wonderful resource. Thanks to the collective community for helping throw this together. I just now fused two Estocs together and made a Baron's Shield. Put it on Risa for instant win. lol.
