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 10, what enemies you'll face, and strategies for defeating them.

Holy See of Hainz Chapter 10 Guide

Best Team to Clear Chapter 10

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

Buffer	Attacker	Buffer	Tank / Debuffer	Buffer
Merlyn Lvl. 120	Florence Lvl. 160	Primavera Lvl. 120	Soltina Lvl. 140	Olivia Lvl. 120
Minimum Recommended BP: 4 - 4.5 million

There wouldn't be too much of a difference between your party in Chapter 9 and Chapter 10. A properly-leveled Florence with the correct runes (SPD, PM DEF Break) and reforged equipment will be more than enough to tear through the enemies in this Chapter.

You may, however, want to switch out Mertillier with Primavera since the former may end up defeated before she can even cast her ATK buff. At least Primavera still has party-wide ATK buffs and the potential to act as a secondary debuffer with her Faint debuff.

Alternative Party Members

Attackers

Cordie

Belle

As always, Cordie is a good attacker, though she might run into trouble during stages where she'll have to face Soltina and her Multi-Barrier. Belle is also another option you can consider, though her status as a limited character makes her tough to build up consistently.

Support

Amour

Mertillier

Like in Chapter 9, there are stages in Chapter 10 where you'll be coming up against healers like Monica. So having Amour along for her Blight debuff is always a good idea. Mertillier will also still be useful as a supporting character, though make sure she'll survive long enough to cast her Maintenance skill at Turn 2.

Holy See of Hainz Quest 10-4 Walkthrough

Notable Enemy/Enemies
Olivia	Illya	Skuld	Loki	Garmr

Minimum Viable Team

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

Buffer	Attacker	Buffer	Tank / Debuffer	Buffer
Merlyn Lvl. 120	Florence Lvl. 140	Primavera Lvl. 120	Amour Lvl. 120	Olivia Lvl. 120
Minimum Recommended BP: 3.5 - 4 million

Tips and Strategies

Make Sure Florence's Stats Are Optimized

You'll be fighting an all-witch party that has an array of skills that can heavily damage your party. The key is to make sure Florence has the right runes and her equipment has been upgraded and even reforged so she has the highest ATK, CRIT, and PM DEF Break and SPD stats possible. She'll need it to take out a majority of the enemy party right at the very onset of the battle.

Bring Amour along to nullify Skuld's Healing Abilities

Skuld's healing abilities can be very potent, making the battle last longer than it should be. So bring Amour along so she can inflict Blight on your enemies, preventing them from getting healed by Skuld.

Notable Enemy/Enemies
Hathor	Olivia	Illya	Monica	Yojimbo

Minimum Viable Team

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

Buffer	Attacker	Buffer	Tank / Debuffer	Buffer
Merlyn Lvl. 120	Florence Lvl. 160	Primavera Lvl. 120	Amour Lvl. 120	Olivia Lvl. 120
Minimum Recommended BP: 4 - 4.5 million

Tips and Strategies

Watch Out for Hathor’s ATK Debuff

Florence might be able to take out Hathor on the first turn, but if she survives, she might be able to use her skill 'Dance of Butterflies' - which has a 50% chance to cut the ATK of the units with the highest HP by half. If Florence gets hit by that, she'll end up with less firepower, which may lead to your defeat.

Holy See of Hainz Quest 10-28 Walkthrough

Notable Enemy/Enemies
Nina	Merlyn	Cherna	Garmr	Military Tactician

Minimum Viable Team

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

Buffer	Attacker	Buffer	Tank / Debuffer	Buffer
Merlyn Lvl. 120	Cordie Lvl. 160	Primavera Lvl. 120	Soltina Lvl. 120	Olivia Lvl. 120
Minimum Recommended BP: 4 - 4.5 million

Tips and Strategies

Make Sure to Outspeed Nina

Nina can get very tough to defeat, so make sure that Cordie's SPD and ACC runes are sufficiently leveled enough for her to make the first move during this battle and try to hit her. There's a good chance that she'll take out the entire party outright, or at least take out the more dangerous witches like Nina and Cherna.
