As a reminder, I would like to leave some notes on this thread.
1.How to heal a slave's stamina during training.
Some races heal the slave's own stamina when training.
However, it is possible for other races to heal their stamina.
Slaves heal about 20% of their stamina by drinking semen.
In order to give a blow job, the slave's pride must be 0% and one of the slave's (Lust, Affection, Taming) must be at least 50%.
To make a slave drink semen, you must have at least 50% Lust, 60% Affection, 50% Training, and half of the maximum skill level.
The maximum skill level of a slave is determined by the number of the slave's arms (or more precisely, the number of hands that can give hand jobs).
If the maximum skill levels are 50, 100, 150, and 350, they should be 25, 50, 75, and 175, respectively.
When a slave drinks semen to regain strength, it does not necessarily have to be a blow job.
As long as a finger or vibrator is in the mouth, it does not matter whether the ejaculation is vaginal or anal.
However, it is after the inserted object is removed from the mouth that stamina heals.
