Yes the Hunter still practice the Spirits' Way but there are some... teological drifting. For exemple the hunters still see the community as a collection of individuals (more alike the diabolist faith) rether than the more olistic spiritist's way (the community is something to which the individual interact).

Similar from a more metaphysical point of view the Hunters downplay the idea of the mana field, and the spirit that inhabits it, as the seed of the new cosmos.

They still belive the mana field as a degree of sentient and magic will revoleve around calling spirits to perform task (rather then knotting and bening it).

Fo this reason they use the most common tecnique of the summoning sigil (a pattern drawn on a surface, either on the spot or pre prepared papers or fabric) and put there offerings (aka material components).

Since they are eager to find the best solutions they will not shy away from more exotic styles of magic: mechanical hounds in the dwarven style; bardic magic to mimic calls; energy bolt in the infernal style to snipe quarries, etc.
