Just want to share a strategy I used to beat this final stage with 35k scores (81 turns, 0 HP dmg, 0 breaks).
Lightning
- 35CP LB1 (equipped)
- 15CP Passive
- 5* Armor 1LB
Papalymo
- 35CP LB1 (equipped)
- 15CP Passive
- 4* Armor MLB
Vincent
- 35CP (equipped)
- 5* Armor 1LB
Summon: Ifrit
Support Friend: Papalymo (3 turns)
The strategy is very straight forward, I go all out since first battle as fast as possible. By the final battle, make sure to have following abilities left:
- 3 charges of Papalymo’s Fire
- 1 charge of Vincent’s Beast Flare
- 1 charge of Vincent’s Livewire Shot
You can use other abilities for 3 first battles since we’re gonna burst the last boss and it will only requires the abilities I mentioned above.
- After entering the last battle, use Beast Flare to weaken the boss to fire elemental, then summon Ifrit.
- Replace Lightning since she’s running out of all her abilities already, swap in Papalymo friend and spam the boss with Fire attacks.
- Use Livewire Shot when it’s Vincent turn. By the end of the summon, I was able to kill it with 2 more turns (HP attacks) and end the battle with 81 turns.
