Rest Time

When Girls adventure in Labyrinths, any HP and MP lost remain with the girls and most be recovered by resting. Girls who have full HP and MP returning from a Labyrinth do not have to rest.

Beds
There are 5 possible beds, with 2 beds unlocked at the beginning. The other 3 beds must be bought from the Cash Shop. Bed 1 has no bonus, Bed 2 reduces time by 1/11. and Beds 3-5 reduce time by 25%.

Formula
The current accepted formula in seconds is: Base Heal Time ＝{(HP Lost×13)＋(MP Lost×2)}×{(Girl's Level＋10)/10}×(Bed Heal Rate) Minimum Heal Time ＝(Girl's Level)×6   *Disregard Bed Heal Rate If the Base heal time is less than the Minimum Heal Time, the Minimum heal time is used instead.

Sleep Aroma
You can use a Sleep Aroma to instantly heal all girls in bed. You can earn Sleep Aromas from Quests and Dailies or find them occasionally in chests.
