@DeNappa Rostering (and championing) doesn’t technically train a power. So by the letter of the daily mission, it shouldn’t count. My workaround for this is to constantly update my 1-star characters that I never use. Instead of selling 3 1-star covers for 300 ISO, I use them to swap powers and claim the daily quest (worth 700 ISO)
Is rostering a character for the first time different than adding a new power (also going from 0 covers to 1)?
Certainly adjusting powers of a championed character should not count for the daily quest. I think that any activity that consumes a cover (or the shard equivalent) from your queue and adds it to your roster should count. I’m unsure about saving a cover, perhaps that should only count when the character is actually championed and the saved covers are applied.
