I'm trying to evolve Bipina as well and not a single lv100 bloom dragon try after try...

Supposedly it's like 10% drop rate.

I already evolved my Cosmos ages ago, but it took me the whole day of farming to get three level 100s, I think.

I guess I got lucky then got enough for both my 5*s needing evolving. Used up most my stamina before leveling and after to do it though...

Does anyone know whether the 80 stamina or the 50 stamina one is more efficient for farming lv100 blooms?

80 stam is better odds of getting the 100 level dragon if you learn how to get all four chests easily. If you already have the 3 medals it pretty easy when not have to worry about getting all monsters

Even if you get only three chests odds are still much better.

Oh the number of medals plays a part? I've been having poor luck with rng and always leaving 1 enemy missed. Thank you, btw.

no I don't think the number of medals matter. It just that if you aren't trying to get medals it is easier to get all chests If you are going solo for chest you can place your team differently
