Research allows T-Dolls to improve their skills and Upgrade Equipment,

It is unlocked after the Commander reaches Level 12.

Skill Training[edit]

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[edit]

The Neural Upgrade system (or Digi-mind upgrade) 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
