| “ | A facility where Rhodes Island Operators can train themselves using the wide variety of equipment available. | ” |
| —Description |
The Training Room is one of the nine RIIC facilities in Arknights. It can only be built on room B305; below the HR Office and to the right of the third Dormitory.
Usage
Once an Operator's skill is upgraded to Level 7, it can be further improved by undergoing Mastery training at the Training Room. Only Elite 2 Operators are able to undergo Mastery training and it only applies to each of their skills instead of all of them simultaneously.
Mastery training can be done by simply assigning the Operator whose skills want to be improved at the Training Room. Another Operator can be assigned as a trainer to speed up the Mastery training process by 5%, which drains their morale as the training progresses. Many Operators have base skills which speeds up the training further, though some also influence this in certain ways such as raising the morale drain rate of the trainer.
Do note that the trainee Operator cannot be removed/replaced throughout the training process. This also prevents the alternate versions of certain Operators to be assigned into any facilities if either is undergoing Mastery training and the player cannot switch between Amiya's versions either.
Levels
| Level | Material | Prerequisite | Training level | Power |
|---|---|---|---|---|
| 1 |  10  2 |
Level 1 Human Resources Office | Mastery 1 | -10 |
| 2 | 60  6 |
Level 3 Control Center | Mastery 2 | -30 |
| 3 | 120  10 |
Level 4 Control Center | Mastery 3 | -60 |
Tips
- If there is no Mastery training in progress, the morale of the trainer Operator will not be drained. This allows the player to assign two Operators in the Training Room for extra Trust.
