Hey there, welcome to this post, This Touhou SouzinengiV -The Genius of Sappheiros- – Boss Guide and Rewards Guide was written to be of use to you, and it is our honest hope that you will find that to be the case.

Home Turf of the Elemental Emperors

Towards the end of the Barrier Distortion, you can find the Elemental Emperors, who possess the Anti-Releaser. Proceed with caution if you wish to defeat them using Akyuu or potentially dangerous moves such as Jesus Crush and Zalam Iblis. Although they no longer have guaranteed ambush turns, their elemental-themed backup makes it easy for them to fill the land gauge and cast spells every turn. To defeat them, use magic of the opposing element and target their backup first.

Boss Guide

As soon as you’re ready, step towards the shrine and confront the game’s final challenge.

Chaos may look intimidating, but it’s a bit more manageable than Chronos. It gets three actions per turn and has access to many skills spanning all magic elements but Light. Expect to see Vacuum Wave, Fire Breath, Onibi, Cold Breath, Thunder Breath, Smoke Bomb, Acid Breath, Toxic Mist, Nerve Destruction, Flare, Peta Flare, Cosmic Liner, Dark Giga Flare, Void Slice, and Meteor. Additionally, it has access to two unique skills: Tartarus Hand, a single target physical Void skill that dispels, and Void Effect, a potent All target magic Void skill that dispels. If it uses Concentrate, it’ll follow it up with either Combination Nova, an All target magic Void spell with 100 Exo, or (if HP is below 50%) Supra Naturalis, an All target magic Void spell with 100 Exo that ignores barriers. On top of everything, Chaos is immune to Void, and its Unknown species means no Slayer effects will work on it.

Right away, it’s essential that none of Chaos’ single-target attacks (Vacuum Wave especially) hit anyone other than your tank. Run Poison Shield with Alice in the decoy slot, and use Hourai Doll on turn 1. From that point, she should use Marionette/Rainbow Parar at every turn. Make sure she has both the Kagami and Magatama equipped. While the descriptions don’t state it, they also reduce Void damage. This is unfortunately not true for the Regalia or Soli Deo. For buffing, stick with Byakuren and only buff Res on your physical attackers and PAtk/MAtk. Having more buffs active seems to make the Void Effect more likely to be used. To deal with Combinatio Nova, use Reimu’s Great Duplex Barrier or Satori’s Reflect Wall to negate the damage completely. If they’re both on cooldown, has Alice use Little Legion and be ready to revive her afterward?

As for Supra Naturalis, the fact that it pierces barriers means that your only real option is Alice’s Little Legion, so once again, be ready to peel her off the floor. Damage-wise, stick with Light damage. You can benefit from land power without Chaos getting the same benefits. Reimu should use Spirit Strike Particle Scatter to cap out Light land on turn 1, then use True Innate Dream, Dream Seal -Zero-, and Hyper Amulet for damage. Try to keep some bombs for Great Duplex Barrier. Satori should spam Punish the Judgment, then swap to Divine Gate when her bombs get low. Try to keep some bombs for Reflect Wall. Your last party member can be anyone, though I recommend Patchouli or Youmu. Patchouli has a chance to double-cast magic if the land power is high enough, and she can score crits with magic. If using her, spam Royal Flare until she runs out of bombs, and then use her skills according to whatever currently has the highest land power. Youmu has a chance to use physical attacks twice in a row, and her DPS is incredible, especially if running Human Realm Sword Stance and Fearless Before Danger to increase her crit damage.

If using her, set Human Realm Sword Stance and Fearless Before Danger on the first two turns, then use Matsuyoi-Reflecting Satellite Slash and Cycle of Reincarnation Slash whenever they’re off cooldown. If spells are on cooldown or Youmu runs out of bombs, switch to Full Moon Slash and Crescent Moon Slash. Reapply her stance and crit buff whenever necessary. As for your commander, Mokou is your best bet. The passively endure chance alongside Phoenix’s Tail and Phoenix Rebirth makes her incredibly helpful for survival. With enough bombs, she can even help you recover after a Void Effect or Meteor gone wrong. High-level Moon Curtains and Galaxy Curtains are important, followed by multi-element resist accessories such as the Soli Deo and Hakurei Garter Belt, PAtk/MAtk boosting, and Light damage boosting equipment.

No matter what, it’ll be a long fight, but with patience and perseverance, you should be able to push through.

Rewards and Final Notes

Upon defeating Chaos, you’ll receive another batch of recipes.

Specifically the Great Orichalcos Crystal-tier weapons.

Additionally, you can retake this quest anytime to revisit the Barrier Distortion and farm Chaos for God Idols. Returning to the shrine will also reveal the actual final two investigations.

These two quests will give you Great Orichalcos Crystals and God Idols, respectively for rematching the Three Goddesses and Resentment Incident with no actual changes to the fights. If you’ve cleared every other quest up to this point, then clearing these last two should get you the achievement “The One Who Clears All”.

Congratulations on clearing Genius of Sappheiros’ final challenge. Give yourself a pat on the back, and enjoy the power trip with your new super hyper ultimate weapons as you wrap up the last little bits of 100% completion.
