How did Milo do that thing with the quarterstaffs? I thought Craft could only be rolled by the day or week?

It doesn’t actually say how long in a day you have to work to craft something. It’s a fair assumption that what you’re making probably takes a solid working day in most cases, but when the thing you’re crafting *literally* takes zero time (because the gp value of a quarterstaff isn’t just very low, it’s actually 0) my opinion is that time isn’t really an issue.

I’d never let that fly in an actual game, though, of course, and you shouldn’t try it.
