I think that Barbarians shouldn't be without magic because
dwarves are essentially physically strong, at least as much as Barbarians)
+dwarves have magic, and what magic it is!
so we need to invent some kind of magic, something like that
magic in the form of totems or maybe blood magic) in general, I don't know, it's just my opinion)
Although, it would be good to make the magic stronger...
But we shouldn't make this magic available to all Barbarian heroes,
only to combat mages (Shamans)...
Divide the "Shaman's Yurt" into two halves, for Barbarian warriors (rituals) and for Barbarian shamans (rituals + magic)...
