And the great soul ticket even has returned. Last time it ran, I got 48 soul tickets out of beating the end boss 6515 times. Fortunately, I've been saving my koban ever since then and now have over 5000 to use for this event. If it takes you a whole bunch of battles to beat the boss, it's not worth it. But if you've got a fairly strong team, this is where you get your SSR and UR generals.
