*sighs* My honour demands an honest answer.
You spend the LP on EXP and grind PER because the second best curio in the game that can be run reliably is glimmer moss. It takes more PER*EXP to find than rustroot, so being able to see rustroot is effectively free. Test mining walls is very much the best way to go when rustroot are a far off dream, but due to rustroots range bonus from Vit quality, you can scan much larger areas much more quickly once you get things rolling.
Beyond that, the subterranean levels become much harder to mine. Even if you can mine second level, it's far more sensible to mine cave level and prospect with a "view range" from rustroot of 10-15 tiles in all directions of your tunnel.
