Encounter with the (Blue) Dragon (Advanced - 80 Sta)

[Zenithale]

I am desperate... do you know the odds to get a Level 100 Bloom Dragon here?

Seriously, already last week I had to run this freaking stage too many times for almost nothing, impossibility to Evolve Bipina cosmosmos for 1 whole week, and today again, 9 tries (= 720 Sta!) for ZERO Level 100 Bloom Dragon... ... and 1 try in the 50 Sta stage and I get one...

(
While I really love FKG Gameplay, especially the Team management I would have loved in Kanpani Girls outside Battlefield, I think the only "difficulty" in that game is just the RNG who might troll you again and again (Bloom Dragon and Arrow Spot who randomly choose the direction for you...). IMO that's a huge potential wasted by pure RNG...
)

I ran 8-9 times this morning/last night and got 6 level 100s... Not sure the odds but I did notice before that I didn't get any lvl 100 until after I got 3 medals, but that could just be do to RNG also...

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?
