Fuga: Melodies of Steel

Hi tank-lovers,

You will unlock the dormitory during chapter 2. After unlocking it, the game will guide you through the facility.
In order to unlock this achievement, you need to be in an intermission, i.e. not in battle.
There, you will need to put a child with a specific status in the dormitory and to sleep.
This will cost you 5 AP of the intermission.

There are 4 status that can/should be healed through sleeping in the dormitory:
- fear: hit rate reduced by 50%
- depression: kid can't use skills or link attacks
- injury: can't go to expedition. Another injury puts you into KO
- KO: kid knocked out, out of combat
This status will be inflicted to the kids during combat, especially if you are struggling.

Put any kid with one of those 4 status in the dormitory to sleep and cheevo will pop.
Hope this helps. Keep on rollin'.
Greetings
