80 bonus stage is 900 Feathers.
fairly sure the 'slots have been loosened' so to say on the gacha got a gold while doing my quest for new faces and took it as a sign
4 golds, 2 new, and the 2 dupes were dupe number 3 - so unlocked the 4th and final slot....does make me realise in over 400 days playing just how many knights I have
Of the 2 new ones, one I really wanted - and Aloe....ah well
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?)
