I'm giving myself 15 days to obtain 40,000 beads.
I must get 40,000 / 15 = 2667 beads per day.
If I aim to get 200 beads per sortie, I must make 2667 / 200 = 14 successful tries each day.
Amount of koban required = 45,000 (taking into account 2 free refills per day)
Hotarumaru (lv 92) , Ishikirimaru (lv 91), Tarou Tachi (lv 70), Iwatooshi (lv 71), Kogitsunemaru(lv90) / Mikazuki (lv68) / Ichigo(lv67) / Tsurumaru(lv 63) in rotation.
Hotarumaru is sometimes able to survive the stronger enemy's hit (2nd card and above)
Level 90 Kogi and Level 67 Ichini seem to be as easily knocked out in 1 hit when facing stronger enemy.
Iwatooshi is most of the time able to one-hit all enemies or a couple, but against stronger enemies, he usually can't one-hit a single enemy.
Have been able to survive up to 3rd-time reinforced enemy. Have not gone up against 4th-time reinforced enemy. Apparently that's a sure defeat?
2nd-time reinforced Naginata have sometimes failed to one-hit any one.
