I was wondering if There is a way to change the artifcer on the site to function of wisdom instead of intellect for home brew / re skin the class as a shaman. I think the class would work really well as shaman with just flavor tweaks but wisdoms would make more sense to me.

 I was kinda blown away how well it transfers. Steel defender = Spirit wolves enhancement shaman, artillerist= totem elemental shaman, alchemist= healing buffing restoration, and my favorite armor = living treant armor.

No, you can't change base class features at the moment. Base class homebrew is on the roadmap.

I'd maybe look at a ranger subclass homebrew to accomplish the same thing

You might be able to change spellcasting ability in subclass settings, but it is for adding spellcasting, so may not work.

You can make a homebrew copy of the subclass and change the spellcasting ability. However, that only affects spellcasting. You may be able to edit some of the other subclass features to work off Wisdom.

You will not be able to edit any base class features outside spellcasting ability.
