If, like me in the previous events, you clear your event missions without remembering how many stamps you collect, here is what I found for the second phase:


Event 2-1
15 stamina
1 stamps 0.0667 Stamp/Stamina

Event 2-2
30 stamina
3 stamps 0.1 Stamp/Stamina

Event 2-3
50 stamina
5 stamps 0.1 Stamp/Stamina

Event 2-4
80 stamina
9 stamps 0.1125 Stamp/Stamina


At least, 2-4 gives more than other stages, unlike in phase 1 where all gave 0.1s/s

(of course, feel free to correct me if I'm wrong)

Aaaaand just now, reading my txt file for this event, I see that I don't have any values for special stages. In fact, I don't even remember getting one from this event, just the raid bosses.
