I wasn't referring to you
The self levelling Lapis/fortune is so slow (as someone else pointed out with some nice math, thank you Peppe) it's hardly noticeable to me, thus my ignorance and confusion about self levelling fortune tools.
I never said the tools were expensive, but that you had to do some work to get the good materials. For this I'm referring to Cobalt and Ardite.
To get significant amounts of these items you need flying (as I find most Ardite is found on the underside of overhangs, but that might just be my luck) and an appropriate pick or the Equal Trade wand foci.
These things are simple to get sure, but it takes some time.
