Please explain what these raidboss slaughter are. Everytime I see a girl with that x% damage against raidboss I just think "Pfff! What a shame this unit only have one useful ability."
What's the point of these x% atk to raid bosses?

On a different note, I still don't understand how that swan race works. I bet on the girls, after checking the results the game says I won and tell me to check my giftbox. I check and there's no rewards. Am I missing something?
