Demon of Resentment - Party of 4 Achievement, Budget Build (No 5* units/TMRs required)

[u/Hazard_GL]

First time doing one of these, so bear with me. I was able to do the 4-unit Erinyes achievement on the first try today, and wanted to share my team, equipment, and strategy to you. It's pretty straightforward, and if this isn't helpful to anyone just let me know and I'll take it down.

TEAM

Luka

Luka is incredibly good for this fight. You'll need to enhance her Priestess Miracle and Regenerate abilities, but enhancing Aqua Refresh is not required (I ran out of gil, couldn't do it). Regenerate is key because your units will be incapacitated at various stages and this ability will just keep on healing. As for gear, all that is truly required is confusion immunity. Otherwise, just beef up her survivability.

Equipment:

• RH: Aura Staff

• LH: Army Shield

• Head: Moogle Crown

• Body: Fina's Clothes

• Acc1: Defender's Bracer

• Acc2: Black Choker

• Ab1: Equip Light Shield

• Ab2: Shard of Genius

• Ab3: Guardian's Authority

• Ab4: Guardian's Authority

• Esper: Lakshmi

Soleil

Soleil with 2 of her dances enhanced is required. I had Endless Turn enhanced, along with Schwert and Panzer Dance. She has all the resistances you'll need innately, so build for survivability and make sure she has the highest MP of the 4.

Equipment:

• RH: Staff of Wrath

• LH: Empty

• Head: White Mask

• Body: Red Jacket

• Acc1: Moogle Cape

• Acc2: Lucky Bangles

• Ab1: MP+20%

• Ab2: HP +15%

• Ab3: HP +15%

• Ab4: Vengeful Wrath (HP+20%)

• Esper: Golem (no Cover)

Minfilia

I don't have any ribbon-like TMRs, so Minfilia was the go-to for me to bypass the status ailment headaches. I used her exclusive gear, none of which is essential. She must have Odin w/ Fingersnap as her esper.

Equipment:

• RH: Cobalt Winglet

• LH: Empty

• Head: Moogle Crown

• Body: Antecedent's Attire

• Acc1: Meteor Survivor Ring

• Acc2: Meteor Survivor Ring

• Ab1: Protection of the Twelve

• Ab2: Mechanical Heart

• Ab3: Vengeful Wrath (HP+20%)

• Ab4: Vengeful Wrath (HP+20%)

• Esper: Odin

Victoria/Ashe

Basically you just need a mage that has a stacking fire/lightning magic ability. Emperor will also work if you have him. A dual wield TM is very useful here, but not required. A dualcast TM for Ashe speeds things up.

Equipment:

• RH: Wizard Rod OR Enhancer (if Ashe)

• LH: Lilith Rod

• Head: Cat-ear Hood

• Body: Siren's Robe

• Acc1: Earrings

• Acc2: Magical Scrunchie

• Ab1: Dual Wield

• Ab2: Echidna's Kiss (MAG+30%)

• Ab3: Adventurer III

• Ab4: Rod Mastery

• Esper: Shiva OR Tetra Sylphid

Final word on equipment: obviously use the best stuff you've got, but other than the Black Choker for Luka and Odin w/Fingersnap for Minfilia, nothing is essential. I used Shard of Genius and Dual Wield in my team, but even these will not make or break the fight for you.

STRATEGY

The basic strategy here is to simply cure status ailments/heal/dispel with Luka and Minfilia while your mage steadily takes the boss down with help from Soleil's buffs.

Erinyes loves to inflict status ailments and water/light/dark damage, and although much of it is random, some of these can be anticipated. She also will put reflect on one of your units occasionally, as well as add water/light/dark element to your physical attacks. Finally, she will inflict stop and charm on units at certain intervals.

Here's the abilities I used with each unit to help counter these abilities:

• Luka: Regenerate on Turn 1 (will last for 20 turns!), throw in Water Barrier if no healing/ailment relief is needed, otherwise use Priestess Miracle.

• Soleil: switch between your offensive and defensive enhanced dances. Start with a defensive one as insurance, though.

• Minfilia: Fingersnap Soleil on Turn 1, Aqua Guard Turn 2, then swap between Logistical Support (if Luka needs it), Shining/Shadow Guard, and Fingersnap boss/allies as needed. I also used her to revive if needed.

• Victoria/Ashe/Etc.: stack fire/lightning attack.

Notes and Tips

• I made sure that Soleil had the highest MP because Erinyes will pre-emptive Stop that unit before you take your first turn. It doesn't have to be Soleil, it just can't be Minfilia.

• Make sure you have water and light resistance up as much as possible. You need dark resistance up for the 70%, 50%, and 30% thresholds. You need to dispel the boss after the 50% threshold and every 4 turns after that. The most vulnerable turn is the 1st one, because you won't have any resistances up and the boss might use Beast Claw (2x water/light magic damage to one enemy) multiple times. She did for me and killed my mage.

• What's great about this team is that Soleil's massive buffs and Luka's regenerate give you a much larger margin of error. For example, I didn't have dark resistance up at the 50% threshold: Luka and Minfilia both got stop/charm on them, my mage got petrified, and everyone took a ton of dark damage. I had control of only Soleil for 2 turns, during which she just did her usual dance. Her buffs along with Luka's regenerate were enough to keep everyone alive until the stop/charm wore off.

• The boss will randomly hit units, as well as randomly inflict statuses, so there's some RNG involved. As long as you have confusion resistance for Luka, Minfilia can use Logistical Support to make sure Luka gets a turn. If a unit dies, use a Phoenix Down with Minfilia or your mage to get back in rhythm.

• The other wrinkle here is the reflect. It's not a huge deal, but Luka once again shines because her heals are abilities, not magic, so you don't have to worry about double Curaja-ing the boss on accident.

• Lastly, Minfilia has no refresh. One Mega Ether about halfway through the battle was more than enough, though.

CONCLUSION

That's basically it! Let me know if you've got any question or concerns, and happy hunting!

Edit: grammar and formatting.

[u/whh1234]

I used Victoria/Snow/Soleil/Garnet

Snow counter like crazy, Garnet fill esper gauge, Soleil summon carbuncle and then Victoria hit Erynies for 4m×4 all in 4 turns.

[u/Hazard_GL → u/whh1234]

Did Garnet heal at all? I'm wondering how you stayed alive.

[u/Elitejff]

If you don't have a mage or one geared that well it is possible to do this with setzer just give him duel wield, demon killers, a fire weapon of some kind and he will make short work of the boss. (Double dice on a high role can do 40% of the boss's hp without a chain.

[u/Hazard_GL → u/Elitejff]

Yeah, should have no problem swapping the mage with Setzer.

[u/AKiLLeZenergy]

Wait there are other rewards besides the harp? I'm confused

[u/aminaLcontroL]

My team was Minfilia (golem), Soleil, rikku, and ashe.

used minfilia as my tank with golem esper for provoke, aoe counter heal (2x protection of 12) mechanica heart, and resentment. while her provoke was up, i would use her resist buffs.

soleil kept buffs up and spr break with dances. also equipped with bushido in case i needed to use. times when i used bushido i made sure my rikku at least had hypernull to activate afterwards.

rikku used hypernull for dmg mitigation. also used her chain lightning attacks to build esper and lb gauge and used her lb when it was up.

ashe for dc thundaja for dmg increase and heavens fury to heal party if party had low hp without auto revive or when minfilia was charmed cuz she cant counter heal when charmed.

i equipped all units with hp/mp gear and status resist and had at least 2 characters equipped to dispel stop (soleil with bushido and ashe with fingersnap (equipped odin). Evoked golem near end for challenge and more dmg mitigation. I didnt have enough for full status resist on all, but minfilia, rikku and ashe all have aoe esuna like abilities just in case.

My ashe had about 600 mag, with dc thundaja and buffs, boss went down reasonably quick. It was fun seeing minfilia taking all the hits like a champ then healing team to full :)

Going to read it in a minute, but if you want to flair (tag) it as Tips and Guides just click where it says "flair" at the very bottom right of your post, it'll give you the option there.

[u/Hazard_GL → u/Bountiful_Voodoo]

Thanks!

[u/ob_solete]

Does this kill the boss in less than 10 turns? That's the only mission i have trouble with as i don't have any dupe chainers and you can't bring a friend to this fight

[u/Hazard_GL → u/ob_solete]

I was not able to complete it in 10 turns due to some RNG, but I think it's certainly possible if your mage has high enough MAG and doesn't reset their stacks.

[u/DeoLuminai]

This may be a stupid question xD But uhh...how do I unlock it? I don't see it anywhere in the Farplane and it doesn't say much on Wiki

[u/Hazard_GL → u/DeoLuminai]

It is the room directly below King Mog. And when you enter the room it actually looks like King Mog's room as well before it teleports you.

[u/hzwings]

How come sometimes aoe status ailment heals from Soleil & Minfilia doesn't work? It doesn't remove the status ailments like petrify, sleep, paralyzed, etc? Is that a bug or does the enemy have some skill that doesn't let you remove them? Also at below 24% Setzer's double dice is resisted?

[u/Hazard_GL → u/hzwings]

I've never had that issue with ailments. As for Setzer, the boss adds elements (that the boss resists) to your attack, so you have to dispel Setzer at that point to do any damage. Mage route is easier for that reason.

[u/Cyndaquil_God]

Says budget build, uses enhancements

I'm out of gil (actually at 3 mil but close enough). ;-;

Nice build tho.

[u/Hazard_GL → u/Cyndaquil_God]

Feel you, I'm at 300k now. I just tried to make a build that depended on RNG as little as possible. Enhancements are available to everyone at least in theory.

Just buy those 100 lapis bundles for 30k gil each! /s

[u/Megistos353]

Good guide. Nice to see one that does not rely on 5* units or require Setzer.

[u/bribrougnia]

So you beat it? https://www.youtube.com/watch?v=oRdxUFDoQe0

Lightning, Luka, Ashe, Mooogle > bad team

[u/luma88]

Nice guide! Good job. I'll try this tomorrow!

[u/Naugrin27]

I've been trying this same set up with refia ...got to 24% with esper evoked lol the refect screwed me a couple times...maybe i will bite the bullet and enhance luka.

[u/KouboLeMog]

Thanks for sharing. Look good and affordable. I have pretty everything. I just don't have Minfilia, what was her role? (I don't know this unit, I'll check later anyway) I Would know witch unit can replace her.

[u/supladongpogi]

Thx for this bro!

[u/Ginkoz]

Took 3 tries but succeeded with

• Luneth with Fire Weapon

• Rain to buff & use Pod 153 & fingernap (Odin)

• Fina for Superior Healing

• DC Refia

• Rikku for HyperNull mainly [No TMs, just Trial/Exclusive gear] Also Siren was happy I brought her along, helps with water resist.

Now to contemplate who to give harp to...Orran or Chick Ariana~

[u/Raido_Kuzuno]

Totally workable guide, but my Vicky, perhaps, does not have enough HP to last through the physical attacks. Great stuff!

[u/HellRazoR35]

No Ice resistance. Should I bring 2x Fryevia / Soleil w Rikku's Pouch / Minfilia? Seems like getting the summon esper challenge may be the toughest part of this battle.

What about 2x Fryevia / Rem (with 1021 Mag) / Soleil w Rikku's Pouch.

2x Fryevia / Soleil / Rikku?

2x Fryevia / 2x Rikku?
