Thread: Ryuujin Invasion Revival event guide

Not taking into account trying to CR Aria and Echidna, as mentioned before it's 1020 MC.
1020 MC / 20 per run (I typically get 21, sometimes 24, occasionally 18 but for simplicity's sake we say 20) = 51 runs - 1 for previous maps

50 runs x 12 stamina = 600 stamina = 25 days (so obviously, natural regeneration alone will not suffice)

THE FOLLOWING ASSUMES LEVEL 200+ SO YOU HAVE MAX OF 18 STAMINA

If we assume you ONLY use SC to refill stamina (and never charisma, since Stamina is the primary issue here):

To reduce 25 days to 7 requires a reduction of 18 days; conveniently, that's our max stamina, therefore you need 24 SC spent on Stamina to reduce it to one week (24 hours in a day x 18 days / 18 stamina per SC spent)

This is to get one copy of each TP unit at a rate of 20 MC per run, assuming no level ups (level up would take out 1 SC), IN THE FIRST WEEK!

If you're willing to go into Week 2, we can cut down our SC spending because we have 7 extra days. 168 extra hours/stamina / 18 stamina per SC = 9.333 SC saved, let's call it 9 so 15 SC spent in 2 weeks to get ONE copy of EVERY TP unit in 2 weeks.

Min-costing Aria and/or Echidna will depend on luck with the CR rolling.
