|Sky Olivia is an amazing upgrade from her normal version with great stats and an (almost) perfect base kit. She’s prepared to be a brave knight and fight for the Shepards.
While Skuld is not an actual weapon in Awakening, it is very useful to have as it boost all the stats to the ally she dances to.
Galeforce is a very important special for dancers and singers to have. Once Sky Olivia defeats an enemy, she will gain another turn to either defeat another enemy or dance to a nearby ally.
Bracing Stance makes her more bulky to any physical or magical attacks. However, that doesn’t mean she can withstand arrows from archers. Distant Counter is also a nice option to have but it’s not 100% crucial. It’s probably best to keep Bracing Stance since Sky Olivia is gonna need a lot of bulk.
Wings of Mercy is also a very important skill for a dancer/singer to have. When her allies are in danger, she can swoop in to finish off the enemy or dance to them allowing her teammate to escape. Aerobatics is also a nice option to have especially since she’s a flier. This will allow her to move farther to her allies. However, Aerobatics is a very rare skills to get and won’t allow for too much movement so Wings of Mercy is a better and more cheaper option to have.
Guidance also makes Sky Olivia even more useful where she allows her allies to travel farther in distance or let’s them cross over small gaps on the maps. It’s just as useful as dancing.
If you happen to get a Sky Olivia with pretty good IVs like +Atk, she should have Breath of Life so she can do some last minute healing to her allies like a Falcon Knight in Awakening. Another option to have (especially if she has -Def) is giving her Distant Defense so she won’t get killed easily. If she has -Atk then she’ll probably need Attack +3 or Attack/Defense +2 unless you don’t expect her to fight a lot.
Overall, Sky Olivia is a very great flying dancer to get. Hope you’re lucky enough to pull her.
