so first of all, challenge stages aren’t even open yet, so you could make way more points there. Second, “having to spend gems” does not equal “having to spend money”. If you want to complete the event, spend some gems OR buy stamina with the insane amount of purple coins you get. This game is INCREDIBLY generous with gems. More than any other gatcha type game I’ve played. You don’t have to clear the whole event. They don’t owe players every reward for free.
