From my calculations, one can acquire
Jubilant fragment boxesx28, 1x per stage from the jackpot 1-9, and then x19 at stage 10.
Jubilant keys from the notes, x1 from 3/3 dc, so 7/week AND 3 from 4/4 weekly challenge(WC not mentioned in the notes, besides the removal of orb fragments being troubling), for 10/wk. x5 week event, 50 jubilant keys. Are there any other sources of jubilant fragment boxes besides? Thats before we ponder what to do on all the characters that didn't get the jackpot that are doing DC's and Weekly challenges. instead of having upto 22 extra keys, those cats will have upto 50 extra keys, which would have been orb of ascension fragments.
Perhaps extra jubilant keys could be fused 6 into an orb of ascension? Kinda feels like this Jubilant event is taking systems that we kind of liked, and making them less good.
Note: Please do not discuss how Jubilant fragment boxes are inferior to dungeon treasure selection boxes for acquisition of elder scale fragments in this thread.
