The last dance.
I leveled up a lot for the optional post-game bosses (I'm level 181 now) so that they don't take a literal century to beat lol.
Strategy:
Sword Dancer 3 might be the easiest Sword Dancer fight just because I have elemental resists now. With Flare Cape, Elemental Guard, Star Bracelet, and Elemental Circlet; I will be immune to fire and earth. This means that the only spells I have to look out for are his lightning spells which are Spark Wave and Indignation which are pretty easy to dodge.
The melee attacks function the same as they did in the second fight.
Sword Dancer 3 also uses Soul Infusion which periodically buffs his ATK/DEF throughout the fight. There's not much I can do about this.
The attack plan I employed here is basically the same as I did in Sword Dancer 2, but it's a lot easier to execute here. I attack him after Death Spiral or a spell and sometimes I'll move back to cast a spell after pushing him into a wall. Backing off to cast a spell is now a lot safer because of my elemental resistances and having access to Mystic Mark alongside Angel Song to boost my casting speed.
I do wonder if there's a good and consistent way to reset combo against Sword Dancer. It's pretty hard because Colette can't get behind him.
