No air summon strategy
I saw a screenshot in one of the Windrunner groups about a fascinating strategy using no air summon at all and using a level 10 gold Runestone of Yoke (Increase Wing Star scores, +50 points) and Runestone of Happiness (Character Wing Star multiplier, x40).
The way it seems to work is that the air summon tends to collects most the wing stars, especially after a start dash going into fever mode. The multiplier is so high that it seems to outweigh the benefit of having an air summon at all.
I read that it works best with Kylie, Scarlet, and Luke. With Kylie, I believe that floating wingstars collected right after getting into fever mode counts with her fever multiplier.
For Scarlet, it's possible that it might still be counted with her dash...?
But why Luke? I don't see anything particularly helpful about Luke for this strategy. Perhaps he is holding some sort of item that was picked up during the start dash.
I don't have the runestones for this strategy so I can't test it but it's fascinating how with all these relics, people are getting creative with different combinations to get high scores.
