Mirabilis

Weapon: Flower of Ease

Assist: Whimsical Dream

Passive A: Distant Counter / Fort. Def/Res 3

Passive B: Sabotage Def / Aerobatics

Passive C: Ground Orders / Guidance

Seal: Guidance / Chill Res

• This set is meant to synergize with non-flier allies on Aether Raids Defense in order to make movement as unpredictable as possible, while also inflicting massive debuffs on Mirabilis' opponents via Whimsical Dream and Sabotage Def.
• There is some overlap between Ground Orders and Guidance, though Guidance is intended for Mirabilis to act as a positional support for allies even if she does not start off next to them to them. If you'd rather rely on Ground Orders, then Chill Res also works well in her seal slot to further debuff her foes and allow her Flower of Ease to activate against them. While Mirabilis does not herself benefit from Chill Res, it can be helpful if she is being used alongside a unit like Thrasir.
• Distant Counter serves to give Mirabilis some opportunity to defend herself if she is attacked by a unit like Kronya or Tharja - both of whom are common on Aether Raids Offense. If positioned well, Mirabilis can be difficult to bait because of her limited melee range, which will often force ranged Vantage users to try and initiate on her to try and prevent her debuffing their Attack in her next turn. If she can KO them in retaliation or simply damage them enough for her team to finish them off, it makes it much more difficult for a Vantage team to defeat her.
• Bracing Stance is superior to Fort.Def/Res but if you do not have the fodder then her native A slot will work just fine.

Weapon: Flower of Ease

Assist: Whimsical Dream

Special: Moonbow

Passive A: Bracing Stance / Distant Counter / Fort. Def/Res

Passive B: Sabotage Def / Flier Formation

Passive C: Air Orders / Ward Fliers

Seal: Flier Formation / Quick Ripsote

• This is very similar to her first set, but tweaked in order to serve flierball defenses. With Ward Fliers from her allies and Bracing Stance, very little threatens Mirabilis, which ensures that she will generally survive in order to utilize her Whimsical Dream dance in your defensive turn.
• Since most flier defenses use Ward Fliers and Goad Fliers to bump up their stats to ridiculous heights, Mirabilis fits right in with her intensive enemy debuffs which further creates a disparity in stats.
• Just like in her other build, Mirabilit can utilize Air Orders and Flier Formation to encourage her team to move unpredictably and catch her opponent unaware.
• Quick Riposte is a necessity if Mirabilis anticipates being attacked by an opponent, as it is the only skill she can learn which will allow her to double - though you want to try and keep her from combat as much as possible.
