Chapter 17 ←Prev

Chapter 19 Next→

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.

Kingdom of Chekkos Chapter 18 Guide

Best Team to Clear Chapter 18

If you have this team or one similar to it, you should be able to clear the entire chapter without issues.

Buffer	Attacker	Debuffer	Debuffer	Debuffer
Merlyn Lvl. 180	Cordie Lvl. 200 - 220	Nina Lvl. 180	Mimi Lvl. 180	Primavera Lvl. 180
Recommended BP: 16-19 million

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.

Alternative Party Members

Attackers

Fia

Sivi

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.

Support

Amleth

Florence

Lunalynn

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.

Note on PM DEF Break Runes

If you somehow haven't been giving the proper runes to your main attacker but still managed to progress through the Main Quest, Chapter 18 is where you will definitely need to start using the right runes. Without PM. DEF Break runes, your main attacker simply will not do enough damage to the enemies on this stage.

The only way to get PM DEF Break runes is by buying them through the shop with Rune Tickets. There are various ways to get Rune Tickets, from farming them in the Temple of Illusions, buying them from Event Shops with Event Currency, buying them with Guild Coins and Grand Coins, and other methods.

If you need to buy a bunch of Rune Tickets quickly, you can buy the Gear Upgrade Gift, Sealed Chest Gifts, and Sealed Key Gifts from the Shop with Diamonds. These packs can get you a good amount of Rune Tickets - maybe even enough to buy a Level 9 PM DEF Break rune straight from the Shop (assuming you bought all the packs).

Premium Gifts

If you want to save time farming for Diamonds that you can use to buy Sealed Chest Gifts, Sealed Key Gifts, and Gear Upgrade Gifts from the shop, Achievement Packs which gives 46,500 total Diamonds for $18.99 can give you additional Diamonds. The Diamonds can be unlocked based on the Chapters you cleared.

Premium Packs	Price	Inclusion
Monthly Boost	$5.99	Diamonds x 150 Gold (24hrs) x 2 Daily
Achievement Pack	$18.99	Diamonds x 46500

Alternatively, You can also get the Monthly Boost for $5.99 which gives 150 Diamonds and Gol (24 hrs) x 2 daily.

Kingdom of Chekkos Quest 18-4 Walkthrough

Notable Enemy/Enemies
Soltina	Luke	Libra	Puppet Soldier	Warlock

Minimum Viable Team

You need at least a team this strong or similar to it to be able to defeat this boss.

Debuffer	Debuffer	Tank	Attacker	Buffer
Mimi Lvl. 180	Primavera Lvl. 180	Amleth Lvl. 180	Cordie Lvl. 200	Merlyn Lvl. 180
Minimum Recommended BP: 17 million

Tips and Strategies

Faint Luke As Soon as Possible

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 Helps Take Out Soltina's Shield

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.

Kingdom of Chekkos Quest 18-7 Walkthrough

Notable Enemy/Enemies
Sonya	Nina	Amleth	Merlyn	Hraesvelgr

Minimum Viable Team

You need at least a team this strong or similar to it to be able to defeat this boss.

Debuffer	Debuffer	Debuffer	Attacker	Buffer
Primavera Lvl. 180	Mimi Lvl. 200	Nina Lvl. 180	Cordie Lvl. 180	Merlyn Lvl. 180
Minimum Recommended BP: 18 million

Tips and Strategies

Have Nina Steal Amleth's Buffs

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.

Resonance Will Help Kill Sonya Quickly

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.

Kingdom of Chekkos Quest 18-20 Walkthrough

Notable Enemy/Enemies
Amleth	Sabrina	Theodora	Arianrhod	Monica

Minimum Viable Team

You need at least a team this strong or similar to it to be able to defeat this boss.

Debuffer	Debuffer	Debuffer	Attacker	Buffer
Mimi Lvl. 180	Primavera Lvl. 180	Nina Lvl. 180	Cordie Lvl. 220	Merlyn Lvl. 180
Minimum Recommended BP: 19 million

Tips and Strategies

Put Primavera in front of Sabrina

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.

Have Nina Take Away Amleth's Buff ASAP

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.
