The Demon Spire is home to some of the most challenging content in the game. Like the tower mode of many other similar games, you clear up to level 60, with each level having increasing difficulty and better rewards. Rewards are calculated based on how many stars you get cumulatively – if you get 3 stars for all 60 stages, you will have 180 in total, allowing you to obtain all possible rewards. However, the requirements for each stage vary and are displayed before you start the battles. Early stages also lock your team to a certain level, forcing you to have evolved units or investment in potentials for the higher levels of the Spire. This guide will attempt to make Spire completion as accessible as possible. Before we begin, please check out the Team Builder to see what basic preparations and team compositions will work well here. 

Every new season the floors drop by 20. Sunken Floors can be found here.
If there’s any mistake or question in the guide, feel free to ask them in Discord.

09/20/22 Update: Since Season 10, the format of the Spire is Changed.
The first 30 floors are migrate of Story Bosses. 35~45 will be the previous Spire’s 50~60. 50~60 will be new Bosses and with SP-level version in 61~63.

Season 10







Heat Blaze Song~!

Smooth Crooner Noel

Dancing Automaton KS-VIII

Troublemaker Mesmiia

Social Butterfly Shizuka

Goal: Kill everyone except Noel.

A very straightforward stage as well. Simplely bring a tank to absorb the silence/paralyze then you can proceed as normal.

Since Mesmiia and Shizuka only attack specific position, you can avoid putting weaker ally on those two positions. Put someone with elemental advantage so they take less damage as well. 

Preferably get rid of Shizuka first because of the Recovery Rate reduction. Or Mesmiia since her paralyze is scary. KS-VIII’s AOE is not threatening even though her debuffs are strong. But after you get rid of other two ST dealer she has no threat.

Sexy Lady's Revenge

Undead Guard Spade

Undead Guard Heart

Necromancer Queen Elizabeth

Undead Guard Diamond

Undead Guard Club

Goal: Reduce Elizabeth’s HP below 25%

A huge stat-check stage for either survivability or burst. If you do not have a META healer or one with recovery rate up like HM Fiora/Christmas Lana (All need 5*), then you would need very high investment to make it up. (If your only healer is Aiko, then you can stop trying) Team like Caesar/Usagi for quick basic attack down targets, or combo team like Bride Baal to burst down targets on combo turns. (Or Bride Baal with Iris, kill fire by fire amirite?)

Remove the guard as early as possible to avoid stacking up too much DOT.
A small mechanic on abilities triggered by Guards’ Death. If you kill X guards at the same turn, all previous abilities will not trigger. Ex. if you killed 3, Absorb Magic I & II will not trigger. Preferably kill 2 guards at the same time to at least avoid the 33% Attack Power buff.

If you have issue sustaining, then kill off Heart and Diamond first to prevent healing reduction. Otherwise kill off Spade/Club if you lack damage. Mix and Match depend on your own situation.

Illusory Mirage

Always Prepared Miru

Big Joystick Usagihime

A straight-forward stat-check stage (yes, again…). Since it asks you finish within 20 turns, it is heavily testing your damage.

The most important thing is to guard your weaker stat ally at 4n turn, since Usagihime’s attack will force taunt on the target, so the rest of her attacks will hit the same target. At 4n+1 turn, DO NOT manually guard, because she would initiate a very heavy ST attack while removing your guard stance. Using a tank will easily able to tank the hits. You can burst Usagihime down to 0% when she’s below 32% HP.

Miru gains total of 80% Damage Reduction plus 25% from her passive, basically Miru has 105% Damage Reduction outside of 4n round when she starts charging. You can try burst her down on those turns. During her charge, u need to hit her 4 times to break it, follow-up attack counts, so usagihime is perfect for this stage.

If you have problem surviving you should get rid of Usagihime first, otherwise get rid of Miru first if you don’t have enough damage. Basic Attack team with Vulnerability Debuffer like Mina/SShizuki can take her down pretty quickly.
