Koda's Blessing required to get "master star"
Koda’s Blessing is not required. I have A Crack in the Ice Mastery without having it.
I wasn’t referring to that achievement, I am specifically referring to the master star under the story panel.
You can fill out all the masteries, including raid masteries, without completing that particular point. You have a choice about which of the options you personally prefer to use.
I know which ‘star’ you mean. It is, indeed, unfortunate that one must complete ‘all’ the available achievements before getting that Story Journal star.
Since you don’t even get anything functional for “story mastery” and this is a relatively minor flavor point, realistically it’s doubtful they’ll spend the development resources to address this. IMO bugs and quality of life should take precedence over these sorts of things, just my 2 cents.
