It is unlocked after the Commander reaches Level 12.

Skill Training

 
Skill training bay.

Training a T-Doll to improving their T-Dolls skill effects and it's activation rate.
Requires Training Data that is acquired from data collection missions. It is also gained via random drop points. To start, tap on an empty slot and select the T-Doll you wish to train.

Research will be completed when the timer hits 00:00:00

The amount and level of training data required for T-Doll skill training varies based on the level of the skill.

Level Training Data Time
Lv. 1 → Lv. 2 100x   1:00:00
Lv. 2 → Lv. 3 200x   2:00:00
Lv. 3 → Lv. 4 300x   3:00:00
Lv. 4 → Lv. 5 120x   4:00:00
Lv. 5 → Lv. 6 200x   6:00:00
Lv. 6 → Lv. 7 300x   9:00:00
Lv. 7 → Lv. 8 400x   12:00:00
Lv. 8 → Lv. 9 200x   18:00:00
Lv. 9 → Lv. 10 300x   24:00:00

Unlike for T-Dolls, the amount of data used for skill training fairies depends on the kind of fairy being trained.

Level Training Data (Strategy Fairy) Training Data (Battle Fairy) Time
Lv. 1 → Lv. 2 200x   200x   2:00:00
Lv. 2 → Lv. 3 400x   400x   6:00:00
Lv. 3 → Lv. 4 600x   600x   10:00:00
Lv. 4 → Lv. 5 240x   200x   14:00:00
Lv. 5 → Lv. 6 400x   400x   20:00:00
Lv. 6 → Lv. 7 600x   600x   26:00:00
Lv. 7 → Lv. 8 800x   200x   32:00:00
Lv. 8 → Lv. 9 400x   400x   40:00:00
Lv. 9 → Lv. 10 600x   600x   48:00:00

Now unlike both the T-dolls and Fairies, HOC's possess 3 skills which require training, not only do they cost a significant amount of data and the fact that all 3 skills must be trained individually, they also require batteries to do skill training. Skill's 2 and 3 have the same amount of data costs as well as the same skill training times, whereas Skill 1 costs double the data and time to complete their skill training.

Level Training Data (Skill 1) Training Data (Skill 2 and 3) Time (Skill 1) Time (Skill 2 and 3) Total Costs
Lv. 1 → Lv. 2 200x   + 50x   100x   + 50x   2:00:00 1:00:00 400x   + 150x  
Lv. 2 → Lv. 3 400x   + 50x   200x   + 50x   4:00:00 2:00:00 800x   + 150x  
Lv. 3 → Lv. 4 600x   + 50x   300x   + 50x   6:00:00 3:00:00 1200x   + 150x  
Lv. 4 → Lv. 5 200x   + 80x   100x   + 80x   12:00:00 6:00:00 400x   + 240x  
Lv. 5 → Lv. 6 400x   + 80x   200x   + 80x   18:00:00 9:00:00 800x   + 240x  
Lv. 6 → Lv. 7 600x   + 80x   300x   + 80x   24:00:00 12:00:00 1200x   + 240x  
Lv. 7 → Lv. 8 200x   + 100x   100x   + 100x   30:00:00 15:00:00 400x   + 300x  
Lv. 8 → Lv. 9 400x   + 100x   200x   + 100x   36:00:00 18:00:00 800x   + 300x  
Lv. 9 → Lv. 10 600x   + 100x   300x   + 100x   48:00:00 24:00:00 1200x   + 300x

Neural Upgrade

The Neural Upgrade system (colloquially called Mod or MOD, translated "Digi-mind upgrade" in CN) is unlocked when the player reaches Commander Level 60.

Certain T-Dolls may undergo neural upgrade, colloquially known as "modding". There are three stages that can be progressively unlocked, each of which unlocks additional benefits. To date, the bonuses granted by all neural upgrades have followed a specific pattern:

Level Benefits
Mod 1 Increases level cap to 110. Increases star rarity, increases buff tile coverage and/or buff value, improves skill multiplier numbers, and increases base stats.
Mod 2 Increases level cap to 115. Unlocks a 2nd skill which must be trained separately and increases base stats.
Mod 3 Increases level cap to 120. Provides a 5 star equipment exclusive to that T-Doll, increases the affection cap for oathed T-Dolls from 150 to 200, unlocks a special skin for the T-Doll which replaces their default costume (Old CG can still be picked and will retain previous voice lines during sorties), and increases base stats.

Unlocking each new modification stage requires that the T-Doll meets certain level and affection requirements, and consumes cores and memory fragments according to the table below. After unlocking Mod 1, oathed T-Dolls gain experience at double the normal rate, including experience gained from auto-battles, combat simulations, or combat reports.

Level Requirements Item Cost (2-Star) Item Cost (3-Star) Item Cost (4-Star) Item Cost (5-Star)
Mod 1 Level 100, 100 Affection, 5x Dummy Links   x200,   x10   x200,   x15   x200,   x20   x200,   x25,   x2
Mod 2 Level 110, 100 Affection   x600,   x20   x800,   x30   x1000,   x40   x1200,   x50,   x3
Mod 3 Level 115, 100 Affection   x1200,   x30   x1600,   x45   x2000,   x60   x2400,   x75,   x5
