Tower of Infinity Guide

MementoMori's Tower of Infinity is a game mode that rewards players with gear and items to strengthen their characters as they progress up the floors of the tower. This guide will teach you about the Tower of Infinity, how to unlock it, the best teams to conquer it, and how to beat the more challenging floors.

Tower of Infinity Guide

Tower of Infinity Gives You Gear and Materials

The Tower of Infinity is a Trial mode that gives you Diamonds, Kindling Orbs, Gold, upgrade materials, and Gear. It's an alternative way to gather resources if you're stuck somewhere in the Main Quest. It's highly recommended that you switch progression between the Tower of Infinity and the Main Quest often to get as many resources as possible.

The difference between Tower of Infinity and the Main Quest is that every Tower stage has MementoMori characters as enemies, unlike in the main quest, where generic non-witch enemies are sprinkled in with the witch enemies. This means every enemy you'll face has unique skills, which you'll have to counter with specific lineups.

Tower of Infinity Unlocks at Quest 2-14

The Tower of Infinity gets unlocked after reaching Quest 2-14, which is a good time to get a boost of resources early on in the game since the tower's first few floors are made up of fragile enemies. The Cave of Space-Time should also be unlocked once you get the Tower of Infinity, which gives you access to even more resources.

Soul Towers Unlock at Quest 8-28

Later on in the Main Quest, you'll have access to four other towers where the enemies are witches of a single Soul type. The caveat here is that you'll also have to use your own witches of a specific soul type as well. For example, if you have access to a Crimson Soul tower, you can only use your own Crimson Soul witches.

Only one of the Soul Towers is open, depending on what day it is of the week, and you can only clear up to 10 floors a day.

Tower of Infinity Tier List

Best Team Comps for Tower of Infinity

Tower of Infinity Team Comp

Buffer	Attacker	Buffer	Debuffer	Buffer
Merlyn	Florence	Mimi	Primavera	Dian

Like in the Main Quest, having a main attacker plus four supporting witches is the most flexible setup when climbing the normal Tower of Infinity. Florence or Cordie will be your main damage dealers, supported by Merlyn's CRIT buff, Mimi's resonance, EVD buffs from Dian, and Primavera, who both buff the party's SPD and prevent the enemies she hits from benefiting from their own buffs.

Azure Tower Team

Buffer	Attacker	Tank	Tank / Debuffer	Debuffer
Fenrir	Florence	Amleth	Soltina	Moddey

For climbing the Azure Tower, you'll have a similar setup with Florence as your main attacker supported by Fenrir and her skill cooldown decrease, Soltina with her Sleep debuffs, and Moddey with her Poison debuffs. Meanwhile, Amleth acts as a tank and a last-resort attacker who will deal great damage to your enemies if she's been brought down to 1 HP.

Crimson Tower Team

Attacker	Tank	Buffer	Buffer	Debuffer
Rean	Amour	Freesia	Dian	Sabrina

Here, your main damage dealer will be Rean, supported by Amour as your tank (with Blight debuffs that will prevent enemies from getting healed), Freesia with her healing ability and EVD buffs, Dian for additional EVD buffs, and Sabrina who will inflict SPD debuffs on your enemies.

Emerald Tower Team

Buffer	Attacker	Buffer	Debuffer	Attacker
Merlyn	Cordie	Mertillier	Nina	Ivy

This is another powerful team featuring one of the two most powerful attackers for PvE: Cordie. She'll be supported by Merlyn, one of the best support witches in the game, because she boosts CRIT and removes debuffs from allies. Mertillier is another good support who can boost Cordie's ATK by 65% provided that she's still alive by Turn 2. Nina and Ivy are here to fill out the roster, but the former has very high EVD, and the latter gets more powerful each time one of her allies is defeated.

Amber Tower Team

Attacker / Debuffer	Buffer	Buffer	Debuffer	Buffer
Mimi	Primavera	Olivia	Hathor	Carol

The Amber Soul category doesn't have a dedicated attacker who is not a limited SR unit aside from Mimi and, probably, Tropon. But the former also has a Resonance ability that allows her to damage enemies with high DEF by attacking the enemy with the lowest DEF instead.

Here, Primavera will support Mimi with her SPD buffs, Olivia with her ATK buffs, Hathor with her ATK debuff for enemies, and Carol with her healing and DEF buffs. If you don't have Carol since she's a limited SR unit, you can slot in Tropon instead to fill the roster out.

How to Beat Tough Tower of Infinity Stages

Tough Tower of Infinity Floors
Floor 110	Floor 118	Floor 137
Floor 145	Floor 153	Floor 185
Floor 216	Floor 245	Floor 250

Floor 110

Floor Enemies
Mertillier	Nina	Soltina	Iris	Illya

The main problems you'll have to deal with are Soltina and Nina. Fortunately, Nina is pretty soft and has a high chance of dying in the first turn, especially if you've been giving ACC runes to your main attacker.

Soltina, meanwhile, has shields that will need to be dealt with, so place a front-attacking witch like Primavera along her line and bring Dian along to raise your main attacker's EVD and prevent them from getting Sleep debuffs.

Floor 118

Floor Enemies
Amleth	Florence	Amleth	Theodora	Arianrhod

You'll face off against three main attackers simultaneously: Two Amleths and a Florence. Luckily for you, however, neither of these Amleths has any Invulnerability buffs (yet), so bringing out a good attacker and having a higher SPD than the enemy should be more than enough to deal with them.

Floor 137

Floor Enemies
Nina	Merlyn	Soltina	Loki	Arianrhod

Watch out for Loki because she can be fast enough to inflict Silence on your main attacker for one turn, leaving you open to attacks from Nina and Soltina. You can either try outspeeding her or, if you have Merlyn, give her just enough SPD runes to act before your main attacker and remove the Silence debuff from them.

Floor 145

Floor Enemies
Soltina	Fenrir	Amleth	Mertillier	Monica

Amleth already has access to her 1-turn Invulnerability buff, so she won't die immediately with 1 hp left and all the power-ups her other abilities grant her. Since it's just for 1 turn, she's not too dangerous, but she's still a risk. You would want to bring along someone who can dispel her buff to make sure she won't pose as big of a threat.

Floor 153

Floor Enemies
Soltina	Merlyn	Florence	Libra	Theodora

This floor can be a bit random in that Merlyn will either buff Soltina or Florence's CRIT and once that happens, your party could be in for a world of hurt. Make sure to outspeed the enemy party with runes and hope that Florence gets taken down first, followed by Merlyn and then Soltina.

Floor 185

Floor Enemies
Amleth	Moddey	Fenrir	Fenrir	Fenrir

The battle can get really crazy because of the presence of three Fenrirs, who can all decrease Moddey and Amleth's skill cooldowns on top of their healing abilities. Make sure your main attacker can deal enough damage to take out most of them in the first turn and bring along a witch that can inflict Blight on the enemy party.

Floor 216

Floor Enemies
Amleth	Cordie	Merlyn	Hathor	Shizu

Another floor that can be dangerous depending on who Merlyn gives her CRIT buff to, on top of Amleth being there with her Invulnerability and Hathor with her ATK debuffs. Merlyn should be able to remove any debuffs your main attacker gets but bring along a second one just in case. Or maybe someone who can steal buffs like Nina.

Floor 245

Floor Enemies
Amleth	Fenrir	Soltina	Freesia	Soltina

This floor can be challenging, depending on who your main attacker is. If it's Cordie, you can bring Dian along for support. If you have Florence, you'll have fewer issues dealing with Soltina, though you could position who does forward attacks (like Primavera) in front of one of the Soltinas.

Floor 250

Floor Enemies
Cordie	Cordie	Mertillier	Fenrir	Rean

Here is a battle straight out of a spaghetti western. Whoever strikes first will most likely win the entire match, with two Cordies supported by Mertillier and Fenrir being capable of wiping your party if you're not prepared. You better have those SPD runes for your main attacker ready.

Tower of Infinity Tips

Get Ready to Switch Gear Between Your Witches

When you finally unlock the Soul towers, you'll be moving your best gear between a lot of witches, especially the gear pieces equipped by your main attacker, as well as any attached runes. It can be annoying to do this all the time, but if you want optimal results, you'll need to be patient and remove your main attacker's gear to give them to your other main attacker for a specific Soul tower.

How to Collect and Enhance Unique Weapons and Gear Sets

Switch Between Tower of Infinity, the Main Quest, and Other Trial Modes Regularly

We said earlier that the Tower of Infinity gives you enough resources to progress through the Main Quest, but this also goes the other way around. The Main Quest can give you the resources necessary to climb up a few more floors on the tower, which will then give you better rewards.

When you're stuck on a floor in the Tower of Infinity, go back to the Main Quest, progress through a few stages, clear a chapter, and then return to the tower. Progression through MementoMori is a marathon, not a sprint, so take your time.

There are also other Trial modes you can gather resources from, such as the Cave of Space-Time and the Fountain of Prayers.

Keep Your Tickets of Infinity

Just like with Boss Tickets, don't use up your Tickets of Infinity immediately. Instead, save them so when you get to floors beyond 200/250 or so, where you can farm lots of materials and gear to make your witches more powerful.
