Frustration is caused by mistaken assumptions..
After chatting with Moor and confirming something i'd heard..
Minecrafting isn't a stand alone skill. It references other skills..
I tried boosting my Carpentry to 90, and now i can reinforce up to 7
times in one mine. This was a single test and I still wasn't able to
reach true bottom with that mine but it gives me options to try.
I'll try boosting Carpentry to max AND mining to same.. assuming that
if it references one relevant skill.. it probably references others.
I'll also try experimenting with better woods for initial supporting as
they seem to be the strongest...
I know i'm talking to myself
