6th Stratum

Special Strategy: 99999 damage

Your first question should be: is it possible? The answer is YES, it does. With the right setup you can deal 99999 damage to Star Devourer, killing it in one hit. I even did special challenge and managed to defeat it with level 20 party members, the threshold level when one character can take mastery class, although some parts are heavily depended on luck. I'll explain the general strategy with the assumption of level 80 party, and I'll add extra notes for you who want to do level 20 challenge like me.

This strategy depends on one particular class, Impact Brawler, and the prerequisite skills are Heavenly Aid - Death Edge combo. Heavenly Aid raises your damage output based on how much HP is recovered during the turn it's activated, and Death Edge's damage is raised higher when your party's HP is lower and the target's HP still have full or most of its health. The mechanics are too complicated to be explained here, but in short, you need both skills at maxed points.

Impact Brawler also needs to have all STR booster skills and equipment. This means maxed Brawl Mastery, Phys ATK Up, Overexertion, Fortitude, Death Edge, and Heavenly Aid. His weapon should be Polydeuces +5, the strongest cestus in the game, buyable after selling Pachyderm Crown, a normal loot obtained after defeating Primordiphant. His accessories should be Fang Helm (+10 ATK), Bracer (+5 ATK), and Yggdrasil Ring (+30 ATK). His race class doesn't matter, but you should learn Bodybuilding and all ATK booster skills when possible. AGI stat doesn't matter. As a backup, you may also want to buy Endyma, Pugilist's strongest armor in the game.

For the rest of your party members, you need to have 3 DEF debuff skills. Deathguard's Eroding Miasma, Rover's Target Arrow, Masurao's Armor Pierce, Necromancer's Wraith Cry, Impulse Arrow's Rain of Ruin, and other skills may be used depending on your party. You also need to have someone who can cast 1 ATK buff. Masurao's High Ground or Shaman's Ruinous Prayer might fits the job. Your Brouni also needs to learn Aegis Shield to nullify Full Burst damage on the first turn.

Their equipment need to have HP booster equipment as many as possible. High HP booster weapons are Yamato Sickle (Harbinger/Botanist), Sphairai (Pugilist), Sarcophagus (Necromancer), and Hell Shooter (Rover/Shaman/Harbinger), but the other type of weapons also have their own HP booster although not as high as those 4 weapons. Their gears should be Orb Gauntlet (+25 HP), Turtle Guards (+25 HP), and Vigor Belt (+100 HP). That the best HP booster gears in this game. About items, don't forget to bring 1 Medica IV, 1 Bravant, and a few Sleep Gas, preferably 5 or more. The optional items including 2 Nectars, and, If you want EXP booster, you can bring 1 Heavenly Gift.

Once you are ready, land on 30F, reduce your health to 1 on the toxic floors in the west side, then open the northern door to find the boss and skip the conversation. At this point I used Ariadne Thread to save my game. This battle should take a few retries until it finally succeeds, unless you are very lucky with the randomness factor.

Basically you need to land 3 debuffs and cast buffs as many as possible.
2Heavenly AidMedica IVSleep GasSleep GasSleep Gas
In order to produce the best result, the boss must be put into sleep during these three attempts. You are trying to land Sleep ailment to the boss with quite high sleep resistance, and that's without lowered ailment resistance debuff and/or LUC booster equipment, so expect a few retries until it succeeds. If it isn't asleep, you may want to consider reloading your game. If the boss isn't asleep, it'll regenerate Agile Sword. The fight can still goes on but you need to deal with another randomness factors later.

-Death EdgeCast ATK buffDefend (or toss Heavenly Gift if needed)DefendDefend
Death Edge has low speed modifier, so the other characters will act before this skill is activated. If all things proceed as planned (everyone at 1 HP except Impact Brawler whose HP is 100%, Impact Brawler has 3 buffs with Heavenly Aid is activated, the boss has 3 debuffs and is still asleep), your damage should be 99999 and instantly kill the boss.
3 (If the boss isn't asleep)
-Death EdgeCast ATK buffSleep GasNectar to fifth characterNectar to fourth character
On this turn you need to move your characters so that they have 3-2 formation. Agile Sword always opens the battle with Sonic Thrust, and it should hit Impact Brawler. If it kills the other front row character, reload your game. If equipped with Endyma, my level 83 Impact Brawler could barely survive the damage with around 30 HP left. However, Sonic Thrust deals line-piercing damage which kills one of your back character. That's why both back row characters toss Nectars on each other to keep both characters alive. The other front character should manage to land sleep before Death Edge is activated, otherwise you won't be able to reach maximum damage.

With this setup I managed to defeat the boss with level 83 party. I failed to inflict sleep on my second turn, so I needed to go through worse condition on the third turn.

Everyone gains 1 level after the fight. This screenshot is captured AFTER EXP calculation

If your damage doesn't even come close to 90k, you may want to read my level 20 setup below to further increase the damage output.

Level 20 Challenge

Its not actually all five members with level 20. Impact Brawler still have normal level but the other 4 members should be at level 20. Remember that this challenge heavily depends on randomness factors, and many part of the battle can screw up the whole plan.

The lack of maximum HP pools forces all party members to have the maximum HP booster equipment. They also should have maxed HP Up skills. Impact Brawler's class must be Therian. Why? Because Therian has Hunting Skill and Brute Strength race skills in addition to Bodybuilding as ATK booster skills. This character also mustn't learn AGI booster skills, it will be explained later. You should also have Divine Herald since it's Vitality Prayer temporarily increase the maximum HP pools. You also need a Brouni with Herbology so that Medica IV recovers 750 HP to fully heal Impact Brawler's HP with Vitality Prayer buff during the turn Heavenly Aid is activated.

The lack of maximum HP pools also forces Impact Brawler to level up as high as possible but his HP should be kept under 535 AND ALSO an even number. Why? I need to explain the mechanics behind this. At maximum level, Vitality Prayer amplifies the maximum health by 1.4. A Brouni with Herbology skill who tosses Medica IV will heal 750 HP. 750 divided by 1.4 equals around 535. Maximum Overexertion reduces HP by 50% and Fortitude amplifies the damage when user's HP is lower than or equal 50%. If HP is an odd number, let's say 101, Overexertion reduces HP by 50, leaving the user with 51 HP which is slightly higher than 50% of the maximum health, thus doesn't activate Fortitude. If HP is an even number, Fortitude will always be activated after Overexertion takes place. That's why you need to keep track of Impact Brawler's HP when leveling him up. 534 should be the optimal number, but lower number should also does the trick. Remember to multiply the number by 1.4 and make sure that it's an even number. For instance, despite 533 is an odd number, 533 * 1.4 equals 746, which is an even number. As in my case a level 93 Impact Brawler with maxed HP Up has 529 HP. However, I tried this strategy with level 99 Impact Brawler for extra stats.

There is another method to overheal during Heavenly Aid is activated, which will increase the damage even further. Merciful Healer has Herb Boost skill which amplifies maximum health up to 1.3 on the turn a Herb skill restores beyond maximum health. However, I couldn't successfully activate this skill as Healing Herb will always goes before Medica IV. My party was built with the consideration of this skill, but I could eventually win without triggering it.

With all of that being said, this was my party for level 20 challenge.

Two extra notes about this setup:

  • As I've said before, I eventually won the fight without triggering Merciful Healer's overheal effect, so this class doesn't serve its purpose during the battle. You can change it with another class, but that character must be able to equip Impulse Arrow bow, as you need to land debuff on your first turn. The second Shaman with level one Heaven's Gift is recommended.
  • Blade Dancer needs to learn AGI booster skills as they are needed for the final part of the strategy, which is heavily depended on luck. Impact Brawler also mustn't learn AGI booster skills to help Blade Dancer in accomplishing his objective.

The strategy changes a little bit. Basically you need to add Vitality Prayer buff in order to increase party members' maximum health, but you need to dispel it in order to have 3 ATK buffs on your Impact Brawler during Death Edge. Impact Pugilist also always goes first before the other 4 characters.

TurnImpact BrawlerBlade DancerDeathguardDivine HeraldMerciful Healer (or Shaman)
1DefendArmor PierceEroding MiasmaVitality PrayerAegis Shield, Rain of Ruin
Impact Brawler can't activate Overexertion as you need Vitality Prayer to be the first buff on him. Since Impact Brawler's AGI is much higher than the rest of the party, he always goes first but he can't do anything at this point. Another note that Armor Pierce and Rain of Ruin have a moderate chance to miss. Armor Pierce can be performed again on the next turn if it misses, but Rain of Ruin must land successfully on this turn. The reason is explained below.
2OverexertionArmor Pierce if misses, otherwise Sleep GasSleep GasSleep GasSleep Gas
If Armor Pierce is missed on your first turn, you can perform it again on this turn, as Blade Dancer's AGI is the second highest on your team. However, you can't perform Rain of Ruin on this turn. Its activation is the lowest so it can wake up the boss when the other character manages to put it into sleep. You MUST successfully put the boss into sleep on this turn. This is the first luck-dependent factor of this battle. You are trying to land sleep ailment with level 20 characters, so it'll take a lot of retries.
3Heavenly AidBravantDefend (or toss Heavenly Gift if needed)Medica IVDefend
As additional note for Merciful Healer, this is the part when I can't trigger overheal effect on this turn. His Healing Herb always goes immediately after Heavenly Gift, and I can't find a way to lower his speed or increase Divine Herald's speed so that Medica IV is tossed before Healing Herb. That's why my Merciful Healer doesn't serve his purpose in this battle. The boss also MUSTN'T wake up at the end of this turn. It has a slight chance to wake up at this point, so you need to restart when it happens.
4Death EdgeHigh Grounddoesn't matter*read below

The second roll of fate happens here. Basically you need High Ground to be activated before Death Edge. Even though Divine Herald's Heaven's Gift may be used on Blade Dancer, this skill unfortunately heals Blade Dancer's HP, which mitigates Death Edge's output. During my countless attempt on this battle, High Ground can finally outspeed Death Edge without changing any setting; it's purely based on luck. When it happens, High Ground will dispel Vitality Prayer buff and become the third ATK buff, so basically now you have the same condition as the normal strategy (everyone at 1 HP except Impact Brawler whose HP is 100%, Impact Brawler has 3 buffs with Heavenly Aid is activated, the boss has 3 debuffs and is still asleep).

If your fifth character is Shaman, you can try to activate Heaven's Gift to Blade Dancer, so High Ground will always be activated before Death Edge. However, Heaven's Gift will remove Blade Dancer's Vitality Prayer buff, and also restore Blade Dancer's HP even with just level one Heaven's Gift, thus reducing Death Edge's damage output. In order to prevent that, you can command the Impact Brawler on your first turn to toss Bravant so that it'll be dispelled instead of Vitality Prayer buff. This strategy is untested so try it on your own risk. If the damage reaches about 90k, don't worry. On your next turn, perform Heaven's Gift - Death Edge combo to deplete the remaining health.

There are many points that may screw up the whole plan, but with perseverance I believe you can finally achieve it.
