The odds are 1 in 300 without shiny charm according to bulbapedia, and 1 in 100 with shiny charm.Are there higher odds of getting a shiny legendary from dynamax adventures?
As I have wanted a shiny palkia for a long time (to complete my palkia collection of course) but have never had good opportunity to find one.
So yes, they're much higher. Only problem is you have to go through the entire gauntlet for each attempt.
I'm still stunned that I got it today. I took a break that lasted months, and only picked it up on Monday because I figured I might as well. Didn't have much time for hunting on Tuesday and Wednesday, and then on the attempt where my hopes were on the Ivysaur, bam, shiny Cresselia...
