I started with one male 3 year old, three male 14 year old and one female 14 year old. I took turns with the males converting the blue masked heathens. As the blue masked and master heathens converted, I included any new male converts in the cycle of conversion. Eventually I had 10 males with at least trainee level Devotion. I choose males because I'm using Grant Youth to cycle them through a few life times to master all disciplines. I'm not using females because there is a bug when you Grant Youth to a female. When she starts nursing, her clock never runs down and she nurses for the rest of her life.
