How to buy in the current event?

I was looking at this post from u/ByWillAlone that shows the cumulative costs for upgrading hero equipment, and I was wondering... Does anybody know what the best buying strategy for these are? (Assuming I won't be able to purchase everything) https://preview.redd.it/4ffesss04wtc1.png?width=1159&format=png&auto=webp&s=6ebcca7c182ec25d67931584b8a79ee03a2dcddc I know you get more ores per medal for the ones in the first row, but should I first try to buy all the starry ores? Maybe the best strat is something weird like "buy the 2*400 glowy first, then 20*350 shiny later" but idk submitted by /u/spartandone [link] [comments]
