Question about Artha for Beginner's Luck

When my character makes a Beginner’s Luck test and spends Artha, where should I mark the Artha? On the skill or the ability?

If I use Beginner’s Luck to make a Falsehood test and spend 2 Persona Points do I mark 2 Persona points spent for Falsehood OR Will?

Mark it against Will. I’d find the page reference, nut I’m not near my book at the moment.

Beginner’s Luck tests are stat tests, so the artha goes to the stat. I believe it’s page 37 of BWG. I’ve posted it a few times here before.
