Download memu, install the amazon apps, download the game from there. Log into facebook on your account. Follow Arus' instructions to create a basic macro for a single run of earth shrine (don't forget to leave excess time/delays to account for slow connection, and slow dual-wield lightnings). Once you have the basic macro, just run it for a while. Alternately, do some math for better efficiency. For instance, I have a spreadsheet that I threw together that lets you input current NRG, length of script (ie, 74 seconds), and desired end time. It tells you how many repeats to do and how long of a delay in each so that you run out of NRG exactly at the desired time. And for what it's worth, Nox and memu both allow delays between scripts, so that shouldn't be a problem.
Alternately, go back in this thread a few pages where I linked to the reddit thread talking about the "blazingfast" script. Follow that. Buy amazon coins, then buy lapis (right now it's $40 for 10200 lapis, black friday sale!). Get TMs in a week. Expect to spend some money, but still a way better bargain than dropping on 10+1 pulls unless you just *need* specific units.
I've personally been abusing the blazingfast macro and I'm finally making some progress on my TMs. I'm only running about 12 hrs per day instead of 24, but it still moves at a decent clip (about 45 seconds per run, each unit gets about 10% per day).
