But offensive pewpew magic have been there as long as Fuling shamans.
It's not new to Valheim.
Only difference besides the type of pewpew, is now our chars can channel into that, no longer just being in the recieving end.
Rubbing the strung head of a dead boss to recieve its power and being able to manifest it at will seems rather magical as well, and has been in the game as long as strining up boss trophies have been a thing.
