Arcanist or Witch: Is there an Archetype that changes the casting stat to Wisdom?

[scary harpy]

I'm wondering if there is a Archetype that changes the casting stat from intelligence to wisdom for the Arcanist and/or Witch?

Thanks.

Nope, only to Cha for Witches if I remember correctly.

However, if you want Wis-based spellcasting, hexes and a familiar, you might be interested into Shaman.

Not allowed by RAW, but you could Ask Your Doctor GM if you could use Blood Arcanist to take the Empyreal variant of the Celestial Bloodline.

If 3rd party material is allowed, you could take the Spell Finesse (Wisdom) feat. Note that this feat does not modify the ability score used for non-spell related class abilities such as hexes.

Good to know.

Thanks to everyone who replied.

For future reference, here's a very nice list of caster variants. There's also a link to a Google doc.
