• Spring Sonya’s strengths perfectly align themselves for an offense-heavy approach (and honestly very little else), so this build aims to complement this by emphasizing her damage first and foremost. An Asset to either of her offensive stats generally works well, though +ATK should ideally be prioritized for greater chances of landing OHKOs.
• The Dazzling Rabbits are fortunately pretty straightforward when it comes to general gameplay, as their primary course of action is simply to initiate against foes as desired while being careful of not overextending too far into enemy range with their warping — and, in case greater burst is needed, use their Harmonized Skill to make up the difference. 
  • For such purposes, Spring Sonya’s base kit works well enough on its own, though switching out Atk/Spd Unity for something that offers a more consistent ceiling (such as Atk/Spd Catch and Swift Sparrow) may be preferred. 
  • Additionally, while it’s not unusable, her default Chill Def/Res is… pretty underwhelming and should ideally be replaced. Among her albeit limited options, S/R Far Trace stands out for the modest damage enhancement it brings via an in-combat Spd/Res debuff and occasional 【Canto (Rem.)】effect should she not warp. Even the more widely-available Wings of Mercy (to augment her potential mobility to its maximum) and Desperation (for consecutive follow-up attacks to circumvent the issues of her bulk) often serve Sonya better than Chill Def/Res, allowing for more consistent benefits to be reaped.
• Further, as she can enable the Duo Hindrance structure and efficiently threaten challenging teams with insane range and commendable upfront damage, Spring Sonya also shines as a compelling choice for one’s Aether Raids Defense team. However, with this setting change, the necessary considerations to make for her build do become a little more intricate as well.
  • Firstly, it’s important to consider the fact that the main draw to Spring Sonya’s offensive prowess — that being Magic Rabbit’s ability to instantly charge her Special without outside assistance — is considered a “start-of-turn” effect, meaning that it can be readily shut down by Elimine’s【False Start】debuff. This can make it slightly unwieldy to utilize her during Astra / Anima Season due to the Scouring Saint’s presence.
  • Her default Atk/Spd Unity interestingly becomes a much more compelling A skill here, as the ubiquity of sources of Atk/Spd-targeting debuffs (e.g. Temari, the Bright Shine structure, etc.) on challenging teams translates to easy exploitation of the skill’s debuff reversal effect. That being said, Sturdy and Mirror Impact are also potential alternatives that should be considered if wishing to give Spring Sonya’s initiations a greater degree of safety.
  • For her C skill, though Spd/Res Hold works perfectly fine for both Sonya and her allies to obtain stat superiority over foes, one can consider replacing it with Fatal Smoke to punish foes even further for baiting her through denial of all healing. Other abilities like Distant or Close Guard may be more impactful depending on Sonya’s specific team composition, though, so her C skill is ultimately flexible.
  • Any Sacred Seal that raises Spring Sonya’s damage can be taken, including those that simultaneously supplement her weaker bulk like Sturdy Blow. Quickened Pulse is an option as well if aiming to use Dragon Fang instead of Luna for her chosen Special, though this makes it doubly imperative to not field her during Elimine’s Season.

Sacred Seal: Quickened Pulse

• Spring Sonya retains the same aggressive playstyle as outlined in the previous build, though this one offers slight differentiation by hinging her offensive performance on the usage of AoE Specials. These Specials offer a particularly high ceiling of potency given their ability to affect multiple foes at once and scale quite nicely with Sonya’s great visible Atk, in addition to working around in-combat detriments as they trigger before.
• Besides her Special, the main difference in terms of her actual build lies in Spring Sonya’s choice of A skill: since the damage calculation for AoE options relies purely on visible stats, it’s necessary to use either Life and Death or Fury to maximize the Dazzling Rabbits’ proficiency at wielding them. Further, the Quickened Pulse Sacred Seal becomes non-negotiable to ensure such Specials are fully charged on turn one, and Chill Def/Res slightly increases in effectiveness due to tampering enemy visible Res (though it’s still far from ideal).
• It’s also worth mentioning that while AoE Specials can be pretty deadly, they’re not very effective if using Spring Sonya in Aether Raids Defense and she’s generally better off using Luna or Dragon Fang instead for such purposes. However, they can be put to decent use within Aether Raids Offense instead. 
  • Given the general closeness of Defense compositions, Spring Sonya can exploit the wide radius of these AoE options to massively wound multiple foes at once while likely taking down at least one — and while Structures and Traps generally make it difficult for traditional nukes to get close enough to actually have an impact, her warping mechanic substantially reduces the strain of having to maneuver around these obstacles.
  • While using her in this context, it’s extremely important to destroy the opposing Healing Tower to ensure the chip damage from her Special activation does not go to waste; for maximum safety, one may even consider using Fatal Smoke to avoid problems if destroying this structure is not possible. 
  • Her Harmonized Skill’s ability to grant two immediate Special charges synergizes nicely with Galeforce strategies, so using Spring Sonya as a support battery at the same time certainly is an option as well — just keep in mind that the ubiquity of the Duo Hindrance structure complicates things if one over-relies on her Harmonized Skill for successful Offense runs.
• Lastly, as for what AoE Special to equip, this will mostly be up to personal preference. Blazing Specials offer a higher damage modifier to secure OHKOs (with Blazing Wind and Blazing Light also offering generous ranges), whereas Growing Specials trade damage for more expansive layouts.
