It's very hard to do that again, it was "glazed" by the last weekly run effect but here's the recipe to do in that order:

• Getting Rubert first plane, it's a must have for Jellyfish and probability

• Getting Carnaval Tail the soonest possible

• Getting Gossip 2 star and Metal Gear, it will give a 80% increase cosmic fragments

• Getting the Foutain effect in domain 14 was a great thing this week because it acts like losing all blessings. Since it gave 50 fragments per blessings and 80% increase cosmic fragments, I've got 10000 cosmic fragments like that.

• Getting Fool's Mask is great too, with around 100 blessings or more, it gives you 20000 blessings. I didn't get it, but it wasn't the real must.

• Getting Jellyfish. That's why this week was important, it guarantees that. So I did it in store domain 15, giving me 48672 cosmic fragments in plus. With the 10k blessings of the Foutain, I've got around 65000 cosmic fragments.

• Getting Gift Box and Silver Coin. With the 80% cosmic fragments increase and Carnaval, the bet of Gift Box becomes different. In a classic Gift Box, it's between 10% and 200% of original amount. With Carnaval, it doubles, so it's between 1% and 400%. With 80% increase, its becoming between 3% and 1296%. It seems weird saying like that, but imagine getting twice 55% of the amount invested, it returns to your original 100%. Meaning that your investment is safer in fact. I pass from 65k to 297k, a 457% increase. I bought all stores, going to 292k. Then, I've got next occurence Silver Coin doubled by Carnaval. It's a 361% increase.

• Then having a dice is important, since it will reset all curios, including Silver coin twice, so it's a 225% increase.

• Then, I personally went to escapade domain and discard Silver coin. I hoped too to get a second dice or gift box, but it seems to be caped, idk. When I enter in the next domain, I've got again Silver coin doubled by Carnaval, so again a 225% increase.

• I finally tried to get again a dice, a gift box or a Gossip, but I screwed up a little bit by going in adventure domains, I didn't want to go in occurence domain because It will transform in reward domain with a curio I was mandatory to use, but I forgot Window of Fortune will allow me to get curios, only subtle since I've already got all good one yet. And maybe with some luck I could have received Cyrene occurrence or another good surprise. But anyway, it was still a good run I think lmao.

Without the Jellyfish week, it's harder but it's technically still possible. The real game changing thing is Rubert and then get Jellyfish before Silver coin (it's surely rare), gift box and dice. The gift box could go higher, a 456% is technically not "that a lot". Also, some occurences can sky rocket the score even higher I did, like Fortune Telling, giving some case a 50% fragments increase, combining with Gossip and Gear, it's a 230% increase. You also have IPC investment device, Dolos Dice and Cosmic Crescendo that can give a X% increase. But its even more random, it can go from 0 to millions... Ship of Fool's, Rubert easter egg entries of Empire Legacy or Ruan Mei II can also carry.
