Usually I have villagers that once they learn how to do a skill it is hard to teach another. They can learn as we know because of the elders. But I have a villager who is in his late 30's (I"M not sure of his age,the last time I checked I think he was 38) and he already had his 3 skills, his building, research,and farming. I thought once he had his first two, That I would have to push for the 3rd like all my others. But he took right to it the first try. He is now doing parenting and he is doing well. He is by the way a runner.
Has anyone ever had a villager complete all the skills? And what would happen if they did? Anything special?

Well i had a villager that was a master in 4 skills and 3/4 adept in 5th but he just wouldnt make it

I have once, but an event caused it ,

It was my first tribe and one of the kids got their name changed to ??due to an EVENT
but to get tech points on all fields, with only a few villagers it was easy to guide him , although what I did , rather than make him master one , then master another I kept him on his toes, so he got points for farming, then I would make him build, oops doc needed , tick , doctor , then go fish , when he had master four I piut him on parent duty , I renamed him John DOE and he died age 72 with a happy totem..
He had a good start in life though so to have a master in all without help , the GAME should reward you !! it is some achievement!!
