Just out of curiosity can you explain why this card is a healer the same as Euterpe? I thought all the new raid bosses were going to have different leader skills so it seems strange to have two with the exact same one. Is there a reason?
There is no hard rule whether cards in a serie will have same passive skills or different passive skills. Since Euterpe and Calliope were quite popular, we are making the light/dark Muse to have their passive leader skill.
