Stage Tips

Each turn, the puppets will attack Dante and Edmond, and increase stacks of "Lure Enemy" and "Lure". When "Lure Enemy" or "Lure" exceeds 6 stacks, the challenge will fail.
When Dante uses "Prepare to Swap", positions 4/5 must perform Strong Attacks on Dante to remove the "Lure Enemy" stacks on him. When Dante uses "Resist Puppets", positions 4/5 must guard to reduce the high turn-by-turn damage received next turn. When Dante uses "Short Rest", positions 4/5 must guard Dante to increase the HP recovered when Dante receives healing next turn. When Dante uses "Run for the Exit", positions 4/5 can attack Dante to help him recover HP.
When Edmond uses "Prepare Change Position", positions 1/2 need to Strong Attack Edmond to remove the "Lure" stacks on him. When Edmond uses "Counter Puppets", positions 1/2 must guard to reduce the high turn-by-turn damage received next turn. When Edmond uses "Brief Rest", positions 1/2 must guard Edmond to increase the HP recovered when Edmond receives healing next turn.
When Edmond uses "Rush for the Exit", positions 1/2 can attack Edmond to help him recover HP.

There is a 17 turn limit, so you must finish by that time!
Focus on the puppets unless otherwise noted. They must all reach 1% to end the fight.
Dante and Edmond cannot reach 1% or you will lose.
"Lure Enemy" stacks also cannot reach 6 or you will fail. Follow directions to avoid this!

On turn 4/12: Use ultimates with slots 4 and 5 on Dante.
On turn 5/13: Guard slots 4 and 5 to lessen the upcoming turn-by-turn damage.
End of turn 5/13: The puppets deal strong turn-by-turn damage on slots 4 and 5.
On turn 6/14: Guard slots 4 and 5 again while targeting Dante.
On turn 7/15: Use basic attacks with slots 4 and 5 on Dante to recover his HP.
On turn 8/16: Use ultimates with slots 1 and 2 on Edmond.
On turn 9/17: Guard slots 1 and 2 to lessen the upcoming turn-by-turn damage.
End of turn 9/17: The puppets deal strong turn-by-turn damage on slots 1 and 2.
On turn 10: Guard slots 1 and 2 again while targeting Edmond.
On turn 11: Use basic attacks with slots 1 and 2 on Edmond to recover his HP.
The above loops immediately, so prepare to use ultimates on Dante on turn 12.

Contraption 02: "[Horror] Challenge - 02"

Enemies

Trial Run Stage Puppet (72,749 HP)
Advance Planning Rei (45,447 HP)
Trial Run Stage Puppet (72,749 HP)

Team Recommendations

At least 4 units that can attack
- Buffers that can attack are helpful
Slot 3's ultimate must be under 4 turns
A multi-target ultimate unit in slot 3 OR units with paralysis resist

Stage Tips

When puppets use "Toxic Gas Leak", you need to attack each puppet 2 times separately to completely remove the stacks from Rei inhaling large amounts of toxic gas, otherwise next turn Rei will fall early due to "Toxic Gas Spread". Attention! If you attack the same puppet too many times, "Puppet Resentment" will increase the puppet's damage, making it impossible to withstand its subsequent damage.
When puppets charge power, the mechanism will restrict all allies except position 3, and position 3 must perform Strong Attack to break the charge, avoiding negative effects from puppets next turn. Especially if the wood-type puppet's charge is not broken, it will cause items to take increased damage, making it harder to withstand "Puppet Resentment" next time.
When Rei charges power, please check the usage instructions of each item, as well as the hints from puppets' "Shadow Flash" and "Rapid Charge", have positions 1/4 perform Strong Attack on the wood-type puppet, and other positions perform Basic Attack on the water-type puppet to trigger the mechanism. Only after successfully triggering at least 4 times can Rei break his charge and avoid falling early. If items are not used according to instructions, you will be ambushed and suffer powerful negative effects.

The puppets must be brought to 1% to end the fight.
Rei and your party cannot die or you will fail.

On turn 3/10/17: Attack the puppets two times each and only that much, no extras (4 hits total)!
End of turn 4/11/18: Slots 1/2/4/5 will be paralyzed this turn.
On turn 5/12/19: Use an ultimate with slot 3 to clear the enemies' charges. If you have units with paralysis resist, you can use their ultimate skills too!
- If you do not have an AoE unit here to clear both charges, focus on the WOOD puppet.
On turn 7/14/21: Use ultimates with slots 1 and 4 on the wood puppet, and basic attacks with the others on the water puppet. Do not use the wrong type of attack, even with buffers/healers, or you will take 300% damage next turn.
The above loops on turn 10, every 7 turns.

Contraption 03: "[Horror] Challenge - 03"

Enemies

Jasper's Essence Box Contraption (642,236 HP)

Team Recommendations

Turn-by-turn damage is more helpful here
Healer in slot 3 or 4

Stage Tips

At the start, "First Experience! Newbie Bonus!" will be provided. Please use the reward to perform Ultimate Skills 5 times to insert essence tokens and activate the contraption.
After "Activate", the "Newbie Tutorial" stage will begin. Please pay attention to the hints on characters - prioritize having position 2 guard and alert the ally in position 1. Have position 1 ally guard, to have position 5 ally gain Taunt effect to smoothly pass the subsequent "Evaluating Results". After "Newbie Tutorial", when the box contraption uses "Work Together", pay attention to hints on allies. Prioritize having the Psychic act first, then have assistants attack to jointly seal 5 times, or else severe punishment will be received.
After "Work Together", pay attention to hints and guard in time before "Essence Release".

Basic attacks make your party take increased damage and reduce your healing, so be careful if you don't need to use them.
To make the enemy take damage, 5 ultimates must be used to activate the box.

On turn 1/7/13: Use all 5 ultimates this turn.
On turn 2/8/14: Guard slot 2, then guard slot 1, then guard slot 5 (they should be taunted). You can do what you want with slots 3 and 4.
End of turn 2/8/14: Slot 5 will be hit if taunted properly, then the whole party will receive damage.
On turn 4/10/16: Attack with your psychics in slots 1 and 4 first. Then attack with the zombie assistants from the right (slot 5, 3, then 2).
End of turn 4/10/16: The party will be hit with a small ultimate.
On turn 6/12/18: Guard all.
End of turn 6/12/18: All party members will be hit with an ultimate.
On turn 7: The above begins to loop so try to have ultimates ready. If for some reason you don't, the turns may shift based on when you activated the box.
