Bit of a tough trial this one!

Thought I'd share what we've worked on in the discord and managed to get a few clears mostly using a team along these lines so if it helps anyone, here it is.

Team gear:

CG Sieghart with 100% passive provoke tank build for DEF and SPR evenly. All he does is guard every turn.

Aerith with Raven Cape for camouflage. Pod 153 equipped. Death resist.

CG Fina with pod equipped. Prompto TMR if possible.

CG Charlotte build for high SPR, aim for at least 900 DEF as well. Death resist.

Summer Folka/Citra as our DPS built for minimum 10k HP. SPR as priority then EVOMAG%.

Strategy follows a simple enough pattern apart from turn 1 and 2.

Turn 1:

• Fill summon gauge with Cilkas.

• Use Charlotte CD for mitigation.

• Fina summons Fenrir.

• Aerith uses mitigation and reraise on Sieghart.

Turn 2:

• Fill summon gauge with Cilkas.

• Aerith pod mitigation or reraise on Charlotte Heal if needed.

• Fina summons Fenrir.

• Charlotte activates magic cover.

Turn 3 onwards:

• Aim to keep mitigation, Pod mitigation and Charlotte DEF/SPR buff with magic mitigation active.

• Debuff resist via Aerith is also very useful.

• Reraise up on everyone at all times.

• Sieghart just keeps on guarding.

Damage strategy:

• Push moon down to between 45-50% HP as quick as you can, then get all apostles down to ~30% HP.

• May need to ST damage the water and light apostles here.

• Aerith using Ancient Holy CD for imperil when needed.

• The turn before crossing 40%, we use Cilka LB for imperil. Very important.

• As we cross 40% we want Charlotte cover, AoE reraise up. Moon will AoE death but then no further actions.

• This turn we will now use Cilka to remove the apostles via her AoE water chaining her CD AoE chaining!

For the rest of the fight it's a little RNG depending on which apostles the Moon will summon. Best bet is to remove them as soon as possible then target moon.

If opposing pairs of elemental apostles are alive (e.g. Light and Dark) then we start getting 1T snorts, 5T berserk etc so avoid at all costs.

Moon will AoE death again at 20% so make sure you have your AoE reraise up at this point as well.

When killing Moon we use CG Fina dualcasting Ultima for magic kill mission.

Each remaining apostle will snort a unit once Moon is dead, so leave no more than 1 alive ideally since they don't hit hard alone and you can survive losing your provoke tank.
