I hope you like soul tickets, because as soul ticket events go, this event ("the rebellion") is the big one. Even the 2000 koban and 2 jade tickets reward for first place is a pittance compared to the soul ticket bounty to be had. I'll be disappointed if I only come away with 50 soul tickets from the two week event.

This event has run before. When it ran before, I beat the end boss 188 times. My totals for that were:

30k copper: 131
weapon: 16
armor: 12
accessory: 12
SSR Takeda Shingen card: 2
100 souls: 13
soul ticket: 2

On that basis, I'm guessing that the loot probabilities go something like:

30k copper: 70%
weapon, armor, accessory: 7% each
100 souls: 7%
SSR Takeda Shingen card: 1%
soul ticket: 1%

If you count getting 100 souls 10 times as a soul ticket, then that's a soul ticket every 60 attempts. Last time the event ran, it took me about 5 battles to get a victory at the start of the event, and was down to 2-3 by the end of it. Now, it's one battle, every time, and nearly always only a two-round battle. I just timed it at 83 seconds from the start of one battle to the start of the next, though that was watching it to click immediately when one battle ended.

And that's without using a fast battle ticket. Spam fast battle tickets and you can burn through it massively faster. If 60 battles costs 60 fast battle tickets and 6 standard rations, that's a pro-rated 120 koban per soul ticket--or slightly more than they charge for a gold ticket, and much less than for a platinum ticket. As of this writing, TruelyNice has already beaten the battle 1131 times. That's a whole lot of soul tickets, and it's just the first day of a two-week event.

That, of course, is assuming that you have a strong team. Most events have the difficulty tuned to cater to newer players with weaker teams, as you don't have to be terribly strong to beat most or all of the opponents of many events. This event is the great outlier. Yes, a weaker player can beat it. But taking 10 or 20 battles to do so rather than 1 scales rewards down accordingly. Even so, this is the second time the event has run, so I'd bet on there being a third in the future once you're stronger.

Normally, I go through and do daily challenges and clear the convoys. Not during this event. Soul tickets are so massively more valuable than the other stuff you can farm. Daily world bosses are still worth it if only because you need the battle rations, though.
