Obviously just a coincidence, but across three accounts when I upgraded Alyssum for the first time (skill/dressblooms plus three blue level five manyus) , all three got the special bonus upgrade to level 29. If only my luck with the gacha was that good.

Maybe you don't know but you can use all of the skill/dressbloom at the same time. It will cost less gold for the same result.

Yeah, that's what I just posted...the seven skill/dressblooms plus three manyus, for a total of ten upgrade materials. Been doing it ever since the first dressbloom event (Mountain Lily?)

Okay. Actually I just missread. I think you got 3 super upgrade in a row but on the same account.
