Scarlet Devil Tower Floor Guide - 21-30F

For the first iteration of the Scarlet Devil Tower (7/17), the effect icons for Solo and All Resist were accidentally reversed on the 5th, 10-20th, and 30th floors. If you aren’t sure of which resist it is, each floor guide mentions the resist type.

So you’ve made it past twenty floors of the Tower, and earned some great rewards along the way. Well, time to take on the next ten floors! This section of the tower goes back to a 3 enemy setup, with the following setup: One named character with a Spell Gauge is accompanied by two generic enemies. The first generic enemy will raise the Yang DEF of all enemies by 2 Levels for 3 Turns and lower the damage all enemies take of a bullet type (such as Missile, or Ofuda) by 30% for 3 turns. The named character will raise all enemies Accuracy by 2 Levels for 2 Turns. Finally, the second generic character will restore 2 Barriers to all enemies and remove 1 Barrier Status from all enemies.

If you think about it, it’s almost like this floor is a series of Touhou sandwiches...

This is a guide to floors 21-30 of the Scarlet Devil Tower. If you’re looking for an overview of  how the Tower works, click here. To return to the floor index, click here.

This first floor basically shows you what you’re in for. Since the third enemy recovers so many barriers per turn on each floor, you have two primary strategies to handle these floors. Firstly, you can take out the enemy that recovers Barriers for all enemies ASAP: this frees you up to break the other two enemies at your leisure. Alternatively, you can aim for some combination of ATK Up and DEF Down to supercharge your All targeting Last Word nukers, as none of the enemies are able to recover HP. 

For this floor, make sure not to bring any Missile-type Last Words, unless you absolutely have to. If you don’t know what damage type a unit’s Last Word is tagged as, you can check either ingame by tapping on the Last Word or by checking their page on GamePress!

Same deal as 21F. This time around, try to avoid Body bullets. Perhaps this is the fairies way of telling Youmu that they don’t want to work their bodies, and instead they want to hurt somebody…? Note that two of the characters on this floor are weak to Fire: an excellent chance to get mileage out of people heavy on Fire breaks.

Same deal as 21F. If you want to aim for Breaking the typeless Tengu, make sure to take out the Earth Tengu as fast as possible, as it’ll quickly remove any Barrier Status you try to apply. This time around, make sure not to bring any Slashing bullets. Training against swords - Sanae couldn’t possibly be teaching them to be knights of the wind, could she?

Same deal as 21F. This time around, try to avoid bringing Energy bullets. Motoori and the fairy maids are just too energetic for that to work! Perhaps they’re just too excited about cleaning Suzunaan - or more likely, they’re up to some mischief. 

Patchouli Knowledge is a particular standout for this floor, as she can quickly Break the Sun Fairy Maid to eliminate the Barrier restoration, and then Break Kosuzu for good measure.

The first major obstacle in this miniboss fight is that both enemies have a Spell Gauge of only 1. Make sure to carefully manage your Barriers, otherwise you’re going to get wiped out in no time. The other major obstacle is Reimu: as she’ll constantly either massively raise the Evasion of her and Kasen for a turn as well as restoring 2 Barriers to them both or lower the Yin ATK of all of your units by a ton for a turn, she’ll make it extremely difficult to take them down, grinding you out until you run out of Barriers and promptly Game Over. In comparison, Kasen is something of a pushover; the Lunar Rabbits do not count as Lunarians, so you only need to avoid bringing Spirits against them for her skills to be relatively unthreatening. 

As such, it’s highly advised to take out Reimu first if possible, as once she’s out of the picture Kasen has no way of keeping herself alive and will thus quickly fall to either damage or Breaks. Alternatively, you can attempt to Break them both on the same turn and then wipe them both out to avoid dealing with the Eva altogether, though you may need to retry the fight if Reimu’s Eva Up causes some inopportune misses.

Since both Kasen and Reimu are weak to Moon, anyone heavy on the Moon breaks such as Luna Child, Patchouli Knowledge, or Reisen U Inaba will cover this fight in a Break eclipse. And as always, for any miniboss or boss floor not immune to Poison, Medicine Melancholy is a fantastic option.

Same deal as 21F. Unfortunately the typeless Spirit is also the one that restores Barrier Status, so you may find it difficult to Break them. If all else fails, remember they can’t heal up! It seems like Byakuren might be trying to lead these spirits to nirvana, but they’re probably just tuning her out whilst smiling and nodding to keep the monk happy. 

Same deal as 21F. Rather odd to see Mokou hanging out with Lunar rabbits, but perhaps she wound up on the moon. Or perhaps she’s just doing it to piss off Kaguya somehow - getting chummy with the Lunarians certainly would do the trick.

Same deal as 21F. Don’t bring any Liquid bullets this time, the spirits don’t appreciate being mistaken for flames. Did you know, the LostWord Discord used to call the Spirit enemies “Fire Homies?” They even used to be an emoji! Alas, they’re no longer our homies. Not since the accident. 

Same deal as 21f. Don’t bring Normal bullets, you wouldn’t want to bore Suwako. Hey, wait a minute, Suwako, you haven’t even shown up in the game yet! Good going, spoiling everyone on how cute your sprite is.

Do note that since Suwako and the Moon Fairy are both weak to Star, units like Marisa Kirisame (both of them) and Star Sapphire will really make them shine! Or - Break their Barriers. One or the other.

Welcome to the third Boss Floor! I think Patchouli might’ve gotten mad at my earlier comments, because not only is she bringing Koakuma along to beat you down, her Extra Attack is specifically designed to counter this guide’s sagely advice: namely keeping you from swapping out in the first place!

The fight is clearly set up in a particular way: Patchouli is meant to bait you to lowering her below 50% HP due to her annoying All resistance and Barrier recovery, just to raise her own Cri ACC to make the most of Koakuma lowering your team’s CRI Def. However, since her base critical hit ratio is pretty small in the first place, this isn’t really much of a detriment.

As such, the best way to handle this fight is to drop Patchouli below 50% HP as soon as possible to remove her annoying first skill, and then promptly take them both out at your leisure. 

A particular standout for this fight is Medicine Melancholy, who can set up a 6 Barrier Break on both foes in a single turn. Additionally, Marisa Kirisame (Witch of Scarlet Dreams) can deliver 3 Breaks to both of them at once with her first Spell Card.
