Shami's Trove

Any of the bcnms themselves have anything worth doing a particular one over the other?

I was curious about this myself. I was spamming Kindergarten Cap because of how fast it was, and I was only running it with my main and pocket BRD. In about 15 runs I've yet to receive a 3rd reward - only the The Thesis and normally a single Dynamis currency. I have received one HMP pouch.

I was curious if doing one of the 6 member BCs might open up the 3rd reward more often.

Hmp pouch is the third reward
Go look at your log, it should be in slot 2

Not really Shami related but I just did a V Formation BC and only the NM spawned.

niiiice~ I got one today as well, but I didn't think much of it.

I've seen that happen twice. I also started the fight with only 10 minutes on the clock once... and with three hours on the clock once.

I don't think it's an event thing, I've had Up In Arms short me on time before too, I imagine it's just something wonky that comes up in the BCNM system that only gets exposed when people start doing a lot of fights in succession.

Heavy Metal Pouch from Gold Chest.

My first time doing Kindergarten Cap only Malodorous Mort showed up. After I finished it I went back to the Wiki page wondering if I read the thing wrong. Each time since then the 2 adds popped with the fight.
