Notes

Ch 1

First chapter, first boss fight!
Flauros is similar to the first encounter against him back in Septem.
He takes 2x damage from Cavalry classes:

He takes 1.5x damage from:

Avoid Knight classes as they are weak against his attacks.
With the correct classes, one should win the damage race with a good Support Servant.

Ch 2-1

Boss Fight!
Melting Furnace Naberius has normal Saber class weaknesses to Archer class Servants, so bring your Archers and this fight should be straight forward. His multi-hitting normal attacks will fill your Servants' NP gauges quickly, enabling you to pile on the damage. Its NP hits AoE but can be nullified with Evade or Invincibility skills.

Ch 2-2

Boss Fight!
A repeat encounter with slightly more HP, although the rules of the fight are essentially the same. Bring Archer class Servants, saving Evade or Invincibility for his NP turn.

Ch 2-3

Boss Fight!
A third encounter with slightly more HP than the previous, although the rules of the fight are still the same. Bring Archer class Servants, saving Evade or Invincibility for his NP turn.

The walkthrough will cover the Main Quest fights in numerical order, but II - VII can be done in any order. All must be completed to unlock Chapter 9.

Boss Information

Solomon has the same weaknesses as a Caster class enemy, but will frequently cast Evade on himself. Invincibility pierce or Sure hit skills and CEs are useful.
Bringing Riders is highly effective.
Normal attack: AoE, Crits: AoE
NP: AoE dmg

Boss Fight!

Boss Information

This encounter ends immediately on Goetia's NP turn (before it is used). As long as the team survives up to this point, the encounter completes successfully. He is Beast I class, and hits AoE with all his attacks, dealing 2x damage to Knight classes and Berserkers, 0.5x damage to Avengers, and 1x damage to all other classes. Since surviving is the only goal in this encounter, as long as low level Knight or Berserker class Servants are avoided, the encounter should be easy to clear.

Boss Information

A detailed guide for this encounter with Solomon can be found here.
Solomon: King of Demon Gods - Goetia 12-2
TL;DR: Weaknesses to Cavalry class Servants, so Riders, Casters, Assassins, and Berserkers are good choices for damage output.
Will insta-NP first turn after casting Invincibility Pierce on self, so either buff block / skill seal / NP seal him or be ready for your front line to be decimated by buff stacking and moving your DPS to the back line.

Boss Fight!

Boss Information

A detailed guide for this encounter with Solomon can be found here.
Solomon: King of Humans - Goetia 14
This encounter is not as difficult as the previous. He has a special passive that allows him to take 1.0x damage from all classes despite being Caster. Rider and Ruler class still resist his attacks. His second passive inflict various debuffs on targets whenever he attacks.
Normal attack: ST (3 types), Crits: ST (3 types)
NP: AoE dmg + Max HP down by 1,000.
He has a total of ten skills.
When he is under approx. 200,000-300,000 HP remaining, he will use a skill that instantly charges his NP gauge, drains his own HP to 1, and will immediately use a high damage AoE attack which will probably eliminate your entire party if unprepared. Thankfully, his normal attacks do not do much damage and have many hits, which will fill NP gauges quickly.
