Honestly I need something like that to happen. When Im pulling good things it makes me want to pull more and spend more, which is bad (but exactly what Goomi intended). I spent way too much last weekend on Cloud's banner but seeing one or two rainbows every other 10+1 made it hard to stop until I snagged that second Elfreeda.This type of fortune has given any motivation I had to spend money on this game to disappear.
I got my kid doing pulls for me... but he likes the yellow crystals the best. So I've burned a few 4* summon tickets and now I think I've created a monster.
edit: hopefully he never pulls a rainbow or I'm boned.
Also- unrelated question, how many dupe 5*s do you need for the STMR when the 7* nonsense goes in?
