It could be said that the actual ranged wizard’s case is not yet present in the game. The mage in NRFW is a “Battle Mage”, the runes that cost stamina are a modification of previous runes that previously had a 50 focus Cost and they inflicted much more damage, which made sense with their slow animation, for this reason they are very clunky, especially when compared to the basic attacks of bows which are instead designed as basic attacks.
