It appears that Spark will increase the bonus in events when using a promoted TF, up to +50%. Only collected through daily quests. First promotion (+5%) is 500, second (+10%) is 1050. Going to take a loooong time to promote up. I promoted Greyslam Grimlock since he’s my go-to when I don’t use the bonus squad, particularly on missile day.
