Will there be this? This is how most people learnt their trade. Sounds a nicer idea then sticking a tick in a box somewhere.
The ‘master’ having to teach the younger generations to pass on their trades… it would happen with most profession/skills I should think.
If it isnt kept on top of them you might lose a valuable skill from the community. Afterall, you cant learn them out of thin air!
Havinga master culd take you up into the higher levels of that skill. Without there would be slow going to learn with many of the harder levels and skills being impossible to learn.
Though taking people into your tribe that wander in could add new or lost skills back on occasion (if you live that long!)
