Mizuki & Caerula Arbor: Cognitive Symbol
| Mizuki & Caerula Arbor features | |||
|---|---|---|---|
| Light | Die | Cognitive Symbol | Cognitive Shaping |
| Memory Mapping | Ecosequence | Caerula Recorder | – |
Unique to Mizuki & Caerula Arbor, Cognitive Symbols are various effects that can influence the player's performance and divided into Enlightenments, Rejections, and Calls of We Many.
Upon entering a new floor except at the start of a run, the player will roll a die which determines whether they would receive an Enlightenment, Rejection, or neither. This die roll's result can be swayed by Light, as shown in the table below.

Enlightenments[edit]
Enlightenments are powerful buffs similar to Plays in Phantom & Crimson Solitaire; the key difference is that multiple Enlightenments can be active at the same time and they will be retained across floors, making Enlightenments much more useful than Plays and can significantly reduce the run's difficulty.

Rejections[edit]
Rejections are debuffs that cripples Operators in the player's lineup which may be afflicted in the die roll upon entering a new floor when the player's Light falls below 100 with increasing frequency at lower Light (see above) or from the effect of 
Caerula Animus, 
Caerula Memory, 
Failed Specimen, and 
"Endless Life" regardless of Light, and can be suppressed by temporarily sending them away through Emergency Dispatch or obtaining 
Dario's Lantern, 
Paraffin and Balsam (costs 30 Light), and 
Tulip's Secret Formula.
Operators being afflicted by a Rejection are marked by their name and rarity turning purple, and a purple mist below their icon. In addition, only one type of Rejection can be afflicted on Operators at a time.
From Mizuki & Caerula Arbor Another Tides, if the player has the "养育者基因种" Collectible, Operators afflicted with Rejections will "assimilate" two Operators in the surrounding 8 tiles that do not have Rejections (including those deployed after them), inflicting them with the same Rejection for the duration of the operation. When an Operator assimilates two healthy Operators, it will instead become Evolved for the rest of the operation (see below).

Hemopoietic Inhibition Operators with this Rejection will continuously lose HP whenever their HP is not fullAccelerated blood cell apoptosis, inhibited bone marrow hematopoiesis
|
|---|---|
 |
Concentration Disorder Operators with this Rejection will automatically activate their skillImpairment of sensory functions, loss of coordination, loss of control over stress mechanisms
|
 |
Neurodegeneration Operators with this Rejection will be Frozen for 15 seconds after deploymentAtrophy of neurons in the brain, delayed reactions, dissociated consciousness
|
 |
Metastatic Aberration Operators with this Rejection have -50% Max HP, ATK, DEF, Deployment Cost, and Redeployment TimeExternal cells observed in circulatory system, ectopic electrical signaling, whole-body tissue spasms

- Hemopoetic Inhibition can be mostly offset if the player have strong Medics who can keep the affected Operator's HP in check.
- Concentration Disorder is irrelevant on passive and automatically triggered skills since the former does not require manual activation and the latter will only be activated at specific conditions. Be sure to switch the afflicted Operator's skill to the auto/passive one if they do have them.
- Neurodegeneration is a death sentence for "helidrop" Operators and can be a major issue for damage-dealing/core Operators, and in Operations where enemies dealing increased damage to Frozen targets are prominent (most notably Leviathan's Followers). Using Therapist Medics can help them get out of the Freeze sooner (or remove it outright if one uses Lumen).
- Metastatic Aberration is the most debilitating, as being at half-strength (but easier to (re)deploy in return) means that the Operator is basically powerless and would incapacitate the whole lineup if the afflicted Operator is their core!

In Mizuki & Caerula Arbor Another Tides, Combined Rejections are introduced, which combines two of the four original Rejections' effects into a single instance that makes them even more crippling. Fortunately, Combined Rejections will only ever be afflicted in a Surging Waves 17 and 18 run, also introduced in Another Tides.

Evolution[edit]
WARNING!
This section contains unmarked spoilers for a subject that is not yet released in the Global server. Read at your own risk!
Added in Mizuki & Caerula Arbor Another Tides, Evolution is a mechanic where an Operator suffering from Rejection manages to overcome their affliction and become stronger, gaining the following effects:
- Name and rarity turn golden.
- No longer suffers the effects of their original Rejection(s) and can no longer be affected by new Rejections.
- Gains 35% Sanctuary.
- Ignores 35% of DEF/RES when dealing damage.
If the player has the "养育者基因种" Collectible, Operators afflicted with Rejections that "assimilate" two healthy Operators in an operation will Evolve for the duration of the operation. Using "Improved Genes" can permanently Evolve one Operator, while using "Improved Genomes" permanently Evolves all currently owned Operators with Rejections.
Calls of We Many[edit]
Calls of We Many are functionally identical to Hallucinations in Crimson Solitaire, but none of them are exclusively detrimental; all Calls provide a positive effect and a negative effect simultaneously, making them more manageable than Hallucinations (although Calls can still put the player in a difficult position regardless).
Calls of We Many will never be heard upon entering a new floor until after the player had completed a run, and the odds of hearing one starts out small but increases at lower Light. Sometimes the player can even hear two Calls at once.

- As with Bewildered in Crimson Solitaire, Echoes: Exploration can be both a blessing and a curse: while one can obtain more resources than normally in the floor, leaking in any operation is twice as punishing, hence one may consider avoiding Operations, especially Emergency Operations, to reduce the chance of messing up.
- Echoes: Predation renders all sources of healing on friendly units impotent which makes taking damage punishing, moreso with faster-attacking enemies. Instead, try to use many helidrops, preferably Specialists or Guards, to make use of the Call's ASPD buff to deal with enemies quickly.
- As with Obsessed in Crimson Solitaire, Echoes: Assimilation allows one to obtain more Originium Ingots, but will be wasted if they aren't spent at all by the time they entered the last node's floor, which can be very punishing if one has Collectibles dependant on the amount of Ingots (e.g.
Chivalric Commandments - New Edition). Hence, one may prioritize spending as many Ingots as possible on Rogue Traders or Downtime Recreations to avoid wasting them. - Echoes: Death and Rebirth is a double-edged sword: on one hand, the player can obtain much more Ingots from operations, while on the other hand, entering it will cost Life Points which may be troublesome if one doesn't have any Objective Shields, since if the lost LP aren't recovered, one may have to face operations without any sort of error! Therefore, if one wasn't confident enough, avoid Operations at all costs to preserve LP for others.
- Echoes: Proliferation allows the player to obtain more Rec. Vouchers than before, which is a plus especially if the player have Operators that deal high Physical damage to work around the enemies' buffed RES.
- Echoes: One Among Many allows the player to increase their Command Level faster, which is a plus especially if the player have Operators that deal high Arts damage to work around the enemies' buffed DEF.
- Echoes: Overgrowth allows the player to increase their Life Point cap, which is great if not because of the fact that LP losses from leaking are doubled, which can be problematic on Dreadful Foes. Hence, one need consider if the Operations ahead can be cleared flawlessly; otherwise, avoid them altogether.
- As with Blind in Crimson Solitaire, Echoes: Adaptation can be easily countered by picking nodes with the most branches and does not matter at all in the 6th floor because its four nodes are fixed. The player is guaranteed to receive its benefit in the 2nd, 4th, and secret floors, as the former two's last node and the latter's first is Wish Fulfilled.
