• This build remains largely centered around maximizing the use of Kronya’s fantastic exclusive weapon, Athame, which allows her to establish a rather potent one-shot playstyle via its unique Vantage-esque effect. Since the primary focus here is her raw damage output, a +ATK IV is thus ideal to further increase Kronya’s firepower, though a neutral IV set is still workable if Trait Fruits are unavailable; further support to her damage output is highly recommended here to solidify her effectiveness. 
• The basic game plan here remains largely the same throughout most game modes, with room for variances depending on the team composition and map one is fighting against: during the initial Player Phase, Kronya should safely initiate on a foe to spread her debuffs and chip damage to debilitate her opponents (thus enabling Athame’s effect), and then unleash havoc in the following Enemy Phase. 
  • To ensure she can safely do so without getting ruined by melee units, Close Foil is recommended (as dragons are not very common in Aether Raids Defense teams) to enable her to counterattack regardless of range; this allows her to cleanly sweep through most enemy forces, and Close Foil even comes with an Attack boost to boot. However, if unavailable or one wishes to stay on the safe side, Close Counter can be taken instead. 
• Since Athame already comes with Vantage built-in, Kronya’s B slot is open to several different options and each are quite effective -- the choice largely depends on personal preference and the type of obstacles one more commonly runs into. 
  • Null C-Disrupt is a highly lucrative option that allows Kronya to mitigate one of the biggest counter strategies to Vantage setups: counterattack negation. This is especially useful in Aether Raids given the prominence of Dazzling Staff users (primarily Brave Veronica) and Firesweep weapons. For a more specialized Aether Raids skill, Disarm Trap makes for a worthwhile consideration to improve her positioning flexibility and safely initiate against her desired target without regard for trap placement.
  • On the other hand, Special Spiral is another exceptional choice for a more damage oriented approach; when paired with Specials that possess a two-turn cooldown and Athame, this allows Kronya to immediately unleash an activation against her opponent in the Enemy Phase before they can even attack. This is also a much more useful generalist choice, unlike Disarm Trap whose functionality exists only in Aether Raids. 
• Kronya’s Special choice depends on her choice of B slot skill. If using Special Spiral, those with a two-turn cooldown are ideal for immediate Special activations; Ruptured Sky and Moonbow are both standout candidates, and Glimmer can be considered as well once one feels confident enough in Kronya’s base firepower. While such Specials can also be used with other B slot skills, using something other than Special Spiral does open up the ability to use Miracle which provides a greatly useful layer of protection -- since even with Athame, taking damage isn’t always avoidable. 
• In either her C slot or seal (or both if so desired), Kronya should be equipped with Savage Blow to apply AoE chip damage on her opponents and activate Athame’s effect, which requires that her foe be below full HP; this also makes it much easier for Kronya to sweep through them in the Enemy Phase. However, one can choose to swap out Savage Blow in her C slot in favor of Pulse Smoke to shut down Infantry Pulse compositions in Aether Raids, which can be some of the most difficult to face otherwise. 
• Although she should typically carry Savage Blow at least as her chosen seal, one can remove it here if they have a reliable external source of chip damage elsewhere on the team, such as through Halloween Hector’s Duo Skill. In such instances, Kronya can take Fierce Stance to further enhance her raw damage output during the Enemy Phase. Note that unlike other Vantage units, a Brazen skill isn’t too great of an alternative here since Kronya can actually maintain relatively high health since her effect is dependent on her foes’ HP instead.
