I see your point. Well, how would you create a Witcher in Burning Wheel? Specifically?
I realize that it is a funnel, but that’s the way being a Witcher usually is in the fiction. I suppose if I compare it to the other Lifepaths, Rogue Wizard for example (which can be entered by meeting 1 of 4 requisite LPs), there could be more variations on the Apprentice Witcher regarding how one comes to be a Witcher.
30 years old. Born villager (10) + lead (1) + Apprentice witcher (5) + Witcher (8 ) + Student of the signs (3) + Witcher alchemist (3).
