lol nice. I just retried a bunch and he always goes next to takumi does the swipe (I guess it's actually judge?) I did get the other pattern before in my video in the first post.
Desperation potion strats:
Day 44: might save a couple seconds, haven't figured it out.
Day 55: Can't find a way to save time.
Day 65:
Day 72: Could be a backup if you get armor at the start. Haven't checked if it actually saves time on waves 2/3.
Day 79: Might save time on wave 1. Wave 2-3: (vid also uses Eat This which I didn't use before, also messed up and forgot to do kurara's attack before takemaru at the end, I don't think waves 4 and 5 change but there's a lot of extra voltage)
Day 86: I don't think it saves time on wave 1 but for waves 2-3:
Day 87: might save time, haven't thought about it yet.
Day 94: 1st battle becomes trivial, could be a backup for wave 2.
I improved the day 72 wave 2 strat. I tried optimizing the shouma strat but this was still better than anything I got using shouma.
There's a very strange thing that can happen where 2 enemies occupy the same spot, specifically at 1:27 in the vid sometimes the yueffoh can go right on top of the darumarr it stopped in front of. If that happens you can't kill the darumarr it's on top of until you kill the yueffoh and start the next turn.
Also here's day 65 with desperation potion that actually works. Depending on the emeny positions, dashing with takumi and agility potion nozomi may not be necessary.
Here's an improved day 1 thanks to shadowfax, also for some reason this skips Sirei's dialogue in the middle of wave 2.
Here's a funny strat for day 79 wave 1 w/ desperation potion using a turret. Could be something better, but this is decently fast.
