Alright, this is literally copy/pasted from my notes. I'm sure a lot of it won't be applicable to a TAS (like refilling on potions), but I really liked the route for RTA. I did the 100-enemy grind before Ortah so I could really blow through that and Sektra. I also did a bit of leveling in the Sektra temple in the room with the 4 water clone (level 3 lightning clears the entire room in one cast). I highly doubt you need to do that for the TAS, but it is a GREAT way to gather exp.
This outline literally just covers the order in which I collect the powerups and which directions I run on the map. I had all the dungeon maps memorized so I never wrote them down. If you need those, I can try to remember and write something up.
The desert/Miraj section has some interesting options. I collect the MP upgrade in the desert cave because I use it for the grind; a TAS will collect this after you get the gloves, when you get the HP upgrade. You can also do the ancient forest fruit grind later (after Ortah, on the way to Orusort), but I do it at that point in the RTA to gain a few levels to make the 100-enemy grind easier and to scoop up the MP upgrade. I also do the save/reload in Miraj after getting the score. You may find a better time to do it, but that has always worked out for me.
