Is there any law in particular that's good for a cultivator that I want to specialize in artifact crafting?
Also how relevant is passion for inner disciple skills? It seems like the only way to improve them is via inspiration XP and it doesn't seem like passion for the skill affects inspiration cost. I have a disciple with 2 stars in magic crafting & magic but 50% match for every law I currently have. Pretty frustrating.
As unknown says Myriad Artifact Law is the king for artifact crafting. Eventually once you brain suck enough people a neutral law like Jade Purity or Primordial Talismans would probably be better.
Passion doesn't really matter at all. It 1) Makes them learn the skill faster, 2) Increases their initial skill in it as a outer by a few ranks, 3) Makes them happier while doing the task.
1 and 2 help, but if you just stick them tailoring a bunch or making a million things of medicine as an outer they get to 20 anyways eventually.
The main thing for 2 is it helps for stuff you can't rank up like qi sense... but it isn't any more helpful then just getting a decent roll on the skill anyways.
For medicine or alchemy I've come to the opinion that the starting skill ranks don't really matter that much and you just want to get a dude with good stats and qi sensing (and artisan for crafting) then just pay to rank the stuff up to 20 once they become an inner.
But if you want to start with a decent alchemy/artifact crafting skill then you want the dude to have a good magic crafting+medicine/craftubg skill.
E: Note that while the starting alchemy skill doesn't matter that much, their compatibility for crafting does, which means you want to either have certain stats high at the start or push them high using cultivation. A maxed out perception+int skill is the difference between 110 alchemy at rank 20 and 40 alchemy at rank 20.
Crafting 50% PER, 20% INT, 30% LUK
Medecine 60% PER, 40% INT
