StreetPass Mii Plaza - Find Mii 2 Main Quest Speedrun Any% in 4:33 (USA)
Bad video layout, I apologize for that. When I try for a better time to beat, I'll make the video layout much better compared to this. I am going to try again just for a sub 4.30 time.
Despite being a great time, this run had a completely unsatisfying ending I did not like in the slightest. I'm going to try and get a better time. A sub 4.30 is possible after this so that will be my goal for this. I apologize for being sad and negative at the end.
Pretty much everyone who did this run went with the same strategy of having all of their Miis line up with only all red colors, and that strategy is the safest option to go for. I came up with my own strategy from the Find Mii 2, 16 Hero Run video I uploaded a few months ago.
I have the first 2 red Miis go through all of the levels. I have a light green on my line for it to be used on the Ultimate Ghost, so it can be put to sleep while the area is filled with intense daring by 2 pink Miis in order to finish it off in 4 strikes. This can kill your run if the Ultimate Ghost wakes up, because he can immediately nullify the magic the pink Miis caused. The Dark Lord thankfully does not nullify any magic so filling up the area with incredible daring by 2 pink Miis will make defeating it less time consuming.
Filling up the room with incredible daring by 2 Miis is very useful against the Ultimate Ghost and the Dark Lord, since they can be taken down with a minimum amount of critical hits. It does come with a risk. You can still miss your attacks, but your accuracy won't be as extremely low compared to one pink Mii filling the room with daring.
I was motivated by @GamingtheOtter since my method of doing this might be the fast way to clear the game according to this. This did spark my curiosity to see if this is in any way a good strategy, but I guess I'll leave that opinion to you guys. This wouldn't be recommended unless you are ok with going through all the risky RNG stuff that happens on the final level. I might change things up at the ending just a bit to see what else can work.
