MementoMori's main quests are split into chapters, and in each chapter, there are some especially difficult boss fights. Read this walkthrough to find out which teams you can use to clear Chapter 18, what enemies you'll face, and strategies for defeating them.
List of Contents
If you have this team or one similar to it, you should be able to clear the entire chapter without issues.

Cordie's your main damage dealer in this team, to be supported by Merlyn and her CRIT boost. It's important that you speed tune your team by giving Merlyn just enough SPD runes so she is the first to move in battle, cast her buff on Cordie, and then have Cordie move immediately after.
Nina is there to steal the enemy's buffs, a skill that becomes particularly useful once you run into Amleth in this Chapter as she can steal her Immortality buffs. Mimi is here to help with her Resonance ability (which can help break up Soltina's multi-barriers; you'll be seeing her a lot), while Primavera should be placed in front of particularly dangerous enemies that are a threat to your main attacker like Sonya.
Make sure that your main attacker (who is most likely Cordie) already has some of the named Gear sets like the Astaroth Set, as well as her unique weapon. That's on top of having a full complement of Runes (PM DEF Break, SPD, ACC, and DEX if you have them), with the PM DEF Break and SPD runes leveled as high as you can afford.
Aim for level 11 PM DEF Break runes on all three of your left-side equipment, as well as level 9 SPD runes. Having them at these levels is not required, but you will have an easier time getting through the chapter if you do.

Fia and Sivi are not only some of the heaviest-hitting witches you can get in the game, but they're also absolute powerhouses in PvE with their ramping damage and tankiness that helps sustain themselves in battle.
However, most free-to-play players will probably not have them from the get-go. If you do have them though, use them.

Amleth is good to bring along as a tank (if you don't have her, Soltina is also a decent alternative). Florence meanwhile can help in breaking multi-barriers with her multi-hit attacks, while Lunalynn can make multiple witches faint with one attack. This makes her useful in stunning whole parties of hard-hitting enemies.

By the end of the first turn, Luke will use her first skill Herald's Flash, and hit your main attacker. Unless you're using Florence as your main, this will most likely kill your main attacker because of the follow-up critical hit Luke will do afterward. The key to preventing this is to get a unit capable of Fainting her and moving before she does. This is most likely going to be Primavera's job, so put her in front of Luke and that problem should be taken care of.
Resonance won't only damage Soltina, but the hits it causes will decrease her Multi-Barriers, eventually breaking them and leaving her open to attack from Cordie by the time her first skill becomes usable again.

When Cordie pops off her nuke in the first turn, one of the possible outcomes is Amleth getting a one-hit KO, though she will revive with her Immortality buff. Having Nina on hand ensures that Amleth's enhanced attack won't become a problem, and she can be taken out as quickly as possible.
If Sonya isn't killed by Cordie's first move, she will in turn kill Cordie with her skills. So it's important to have Nina along for the resonance debuff; it will link Sonya and the Hraesvelgr enemy together, making sure that she gets so many hits that even if Cordie's nuke does not kill her, then your other witches will. Though, for backup, have Primavera on hand so she can faint Sonya.

Sabrina is the most dangerous unit in the enemy team, so she'll have to either be taken out first or, failing that, be Fainted by Primavera. If you fail to faint her, she'll immediately take Cordie out, leaving the rest of your party open to attack.
This should be easy to do because most of the time, Cordie's first skill will target Monica and Mimi's Resonance will send half of all that damage Amleth's way (which should be enough to defeat her and trigger invulnerability). Speed-tuning your Nina to move just after Cordie will make sure she'll be able to snatch Amleth's buff as soon as possible and she stops being a problem.
