Ch13 v3:
http://dehacked.2y.net/microstorage.php/info/1977039107/FE6%20TAS%20Ch13v3%20WIP.vbm
Well, not only did I redo Ch12 AGAIN, I've redone Ch13 too. Managed to make some further savings across both chapters, but made a bit of a loss in one place.
Ch12 is almost exactly the same, except Roy keeps the Door Key and doesn't trade it across to Alan, so I save time by not having to take it back. Slight improvement by not getting hit on turn 20 enemy phase too. 67 frames saved here, on top of the 171 from the previous version.
Ch13 was a new kettle of fish. I reverted to getting the first version's turn 1 enemy phase, with 2 critical hits and a HP, Str, Skl, Spd level up. I actually set up the RNG in the previous turn so that I needed no manipulation to do this. Alan takes a hit on his first enemy though, but its not a problem
Turn 2: Less trading here, since Zealot wants to empty his inventory. Roy takes the Steel Lance and Steel Sword from him. Alan had taken the Javelin and Killing Edge as before in the previous turn. Marcus again crits the Troubadour, and finish in the same positions as last time.
Turn 3: More new changes - Zealot drops Roy, so Miledy can pick up Zealot and save me having to move him next turn to avoid the enemies on Turn 6. Marcus picks up Roy and moves as normal. Alan positions himself forward, holding a 10 use Hand Axe and full Javelin in second position. You might not think it, but this is the exact RNG manipulation used in the previous version - something caused Alan to miss on the second-to-last enemy, which is the biggest loss in this entire version. Still, I finish overall much faster. I save time by skipping the Sophia visiting Cecilia cutscene early.
Turn 4: Again, more cutscene savings by skipping the move back across after a unit moves. Marcus finishes off the awkward cavalier, and I finally realise I don't need a crit to kill the Troubadour, which makes manipulating the double miss on Lalum easier.
Turn 5: Pervical recruited, Marcus deals with his inventory issues (dumps the Hammer, Hand Axe and 12 use Javelin on Roy, destroys the 1 use Javelin). Alan crits the wyverns as before.
Turn 6: Now that I have Roy C support, I can reach an earlier critical than before on the boss (RN for crit is 33, Alan has 31 crt with Killing Edge, 36 with Roy support).
Turn 7: Marcus goes shopping. Roy seize.
Total saving 77 frames in Ch13, 144 between Ch12 and 13 in this version.
I think I can stop optimising here. Time to move on Ch14, finally.
