Fluorescent Sea Whispers

Chasm - 01: "[Fluorescent] Challenge - 01"

Enemies

Challenge the Unknown Kuya (14,869 HP)
Understand the Unknown Olivine (16,810 HP)

Team Recommendations

Bring at least 3 attacking units, and at least 2 of those should be strikers or saboteurs.
No turn-by-turn (bleed) units, and avoid anti-recovery (Kuya) units.
No allies that generate shields.
Supports that deal damage are useful here.
AoE units are also very useful.

Stage Tips

At the start of the battle, Olivine will perform "Weaken" 4 times. Please enter guard stance to protect yourself from falling early.
Once "Unknown Power" affects Olivine, Normal Attacks can be used to heal him. When Kuya performs "Locked On" and Olivine assists with "Suppress", all allies will gain a massive shield. Perform Normal Attacks to consume the shield and withstand Kuya's "Counterattack".
When Kuya begins charging and Olivine uses "Draw Attention" to Taunt, one ally must attack to let the <Striker> and <Saboteur> gain "Fluorescent Splash". Then, allies with "Fluorescent Splash" must perform a Strong Attack to remove Olivine's high ATK. Next, let the allied <Striker> and <Saboteur> gain "Flesh Rift". Finally, allies with "Flesh Rift" must perform another Strong Attack to break Olivine's Taunt. Note! Ultimate Skill damage still cannot be dealt to Kuya at this time; use Normal Attacks to interrupt Kuya's charge.

While Kuya needs to be brought down to 1% HP, Olivine must be healed instead to 100% HP. From turn 3 onward, he will be healed by every basic attack you perform on him.
Focus on Olivine first! If Kuya is brought to 1% and must have his charge interrupted, you may lose the fight.

On turn 1: You can't do anything, so just guard.
On turn 2: You still can't do anything so guard again.
On turn 3/8/13: Kuya will taunt, so just use basic attacks to try to remove your shields.
End of turn 3/8/13: Kuya will attack the party based on the amount left on the shield, and Olivine will also take damage.
On turn 5/10/15: Attack with anyone (preferably a support unit) to grant strikers and saboteurs the ability to lower Olivine's attack. Ultimate with one striker/saboteur, which then grants the next striker/saboteur the ability to remove Olivine's taunt. Finally, attack Kuya with a basic attack to cancel his charge.
- TLDR: Support Attack on Olivine > Striker/Saboteur Ultimate on Olivine > Striker/Saboteur Ultimate on Olivine > Any basic attack left that hits on Kuya
End of turn 5/10/15: Olivine will use an ultimate on the party.

Chasm - 02: "[Fluorescent] Challenge - 02"

Enemies

Deep Sea Strange Freak (215,843 HP)

Team Recommendations

Elements don't matter here.
Turn-by-turn and ultimate users are recommended but not necessary.

Stage Tips

On specific turns, <Deep Sea Freak> will cause all allies to fall into "Absent-minded". Basic Attacks can help reduce the shields of adjacent allies to deal with the upcoming "Mental Shock".
When <Deep Sea Freak> causes "Mental Dissolution", please enter guard stance to reduce shields or use Basic Attacks to increase shields based on the team's HP to deal with the subsequent "Attempted Attack" of <Deep Sea Freak>.
When <Deep Sea Freak> causes an ally's "Worsening Infection", using a Strong Attack can protect oneself from the effects of the "Call of the Abyss".

Basic attacks will cause you to attack the two units surrounding your attacker. This includes those who do not damage the enemy!
Attacking your party members is a GOOD thing to deplete their shields. Damage will be dealt to everyone based on the shield amount, so you don't want it to be too high.
You will be hit nearly every turn by attacks based on your remaining shield, and granted another one.

On turn 3/9/15: Guard all to remove the shield effect. If you end up damaging yourself too much, try to basic attack once or twice before guarding to not remove too much past the shield, or just use your healer last.
End of turn 3/9/15: The party will be hit by a strong ultimate, which is stronger if any shield remains.
On turn 6/12/18: Use ultimates with everyone to remove the shield effect this time.
End of turn 6/12/18: The party will be hit by a strong ultimate, which is stronger if any shield remains.

Chasm - 03: "[Fluorescent] Challenge - 03"

Enemies

Mysterious Flesh (144,485 HP)
Trance Olivine (882,565 HP -> 617,796 HP)

Team Recommendations

Bring basic attackers if you have them!
Low cooldown ultimate users are recommended as well.

Stage Tips

When <Trance Olivine> is in "Struggle for Consciousness", please use at least 4 Strong Attacks to strengthen his will. Otherwise, he will fall into "Dazed Consciousness", increasing the damage he deals.
When <Mysterious Flesh> performs "Mental Contagion", use Normal Attacks to stay conscious. If any ally remains asleep, Olivine will experience "Loss of Consciousness", leading to battle failure.
When <Mysterious Flesh> begins "Mind Devour", attacking will grant the entire team a shield to resist "Mental Shatter". Note that Ultimate Skill cooldowns will be frozen for 3 turns. If you cannot counter the following "Struggle for Consciousness", allowing Olivine to enter "Dazed Consciousness" too many times will significantly increase the challenge difficulty.

Focus only on Olivine unless noted since the Flesh cannot be damaged. Only Olivine must reach 1% to win the fight.
Do not let Olivine's HP recover to 100% or you will lose the fight early.
Olivine will gain effects when he hits certain thresholds to hinder you further, so be prepared:
- 50% HP: Olivine's attacks will do more damage.
- 30% HP: Olivine will heal faster.

On turn 5/12/19: Use at least 4 ultimates on this turn on Olivine.
On turn 7/14/21: Use basic attacks in order of the allies that wake up.
End of turn 9/16/23: The party will be hit with a small ultimate this turn.
On turn 10/17/24: Attack with everyone to gain a shield, but your ultimate cooldown will be paused for 3 turns. If you think you can survive, you can guard instead.
