Naga (Unit)

Weapon: Divine Breath (+Eff)

Assist: Positional Assist

Special: Moonbow / Luna 

Passive A: Fury 

Passive B: Chill Skills / Snag Skills / Near Trace Skills 

Passive C: Divine Fang+

Sacred Seal: Ground Orders / Air Orders / Guidance / Drive Skills / Chill Skills 

• Naga’s primary value in a given team remains firmly as an offensive battery for her team via her upgraded Divine Fang, so doubling down on this support role to buff allies while sticking in the backline naturally thus becomes her best option — especially given her inability to equip Galeforce. Since she typically won’t be seeing combat much here, her IVs don’t particularly matter so any can work here.
• Fury is Naga’s ideal A skill here to supplement her overall statline modestly in case she ever does need to engage in combat — while not comparable to some of the more high-end offensive A skills available, it’s more than enough for her purposes and its third tier version thankfully remains readily available. For her Special, Moonbow or Luna are good for their short cooldowns and usefulness against bulkier opponents.
• For her B skill, as she already provides a whopping +6 visible Atk/Spd for free with Divine Fang+, Naga is generally better off going for debuffing skills to round out the stat swings she can impart. Chills and Snag skills are both great for these purposes (with the latter working well if using Smite has her Assist), with Sabotages being a non-option due to her Res being rather abysmal. Alternatively, one can consider a Near Trace to have Naga safely destroy opposing structures and retreat.
• The Ground Orders Sacred Seal is a phenomenal choice to further supercharge allies with flexible mobility in addition to Divine Fang’s benefits, leveraging her flying status. A potential alternative, if unavailable, is Guidance, but it requires that Naga actively approach the enemy team alongside her allies to reap its benefits (as opposed to Ground Orders which extends the buff at the start of the turn). Otherwise, a Drive or Tactic of your choice can work for more stat swings.

Weapon: Divine Breath (+Eff)

Assist: Positional Assist

Special: Moonbow / Glimmer / Luna

Passive A: Swift Sparrow / Atk/Spd Catch / Atk/Spd Solo 

Passive B: Dive-Bomb / Near Trace Skills

Passive C: Divine Fang+

Sacred Seal: Atk/Spd Form / Swift Sparrow / Atk/Spd Solo 

• Alternatively, since Naga keeps the crux of her utility by simply keeping Divine Fang+ equipped and is able to simultaneously apply its buffs to herself, she can opt for more of a combat focus to clean up lingering foes that her allies may have left behind. A +ATK or +SPD Asset work well to elevate her damage potential.
• Keep in mind, however, that Naga relies heavily on Divine Breath’s in-combat boosts for her combat performance, which makes it very important to keep allies adjacent to her for her dragonslaying buff (since most Player Phase focused Offense teams are unlikely to carry other dragons). 
• Moonbow and Luna once again shine as Naga’s Special of choice here, helping her cut through enemy defenses with more ease; if confident in her damage, though, you can also consider Glimmer for its short cooldown and higher ceiling. For her A skill, anything that enhances both Atk and Spd works well, with Swift Sparrow, Atk/Spd Catch, and Atk/Spd Solo being among her best options. (Please don’t stick with her default AR-O Atk/Spd, though — it’s really bad).
• Dive-Bomb synergizes excellently with the automatic follow-up effect from Divine Fang+, allowing Naga to strike against a foe twice consecutively with minimal effort — just be sure she doesn’t take too much damage should this skill remain equipped. A choice of Near Trace (though ideally A/R or S/R Near Trace) may also work well for more of a hit-and-run approach, or for more flexible movement in general.
• Similar to her A skill, any Sacred Seal that boosts her two offensive stats should be prioritized over all other options. Atk/Spd Form synergizes nicely given that she already requires nearby allies for optimal performance (and carries a higher ceiling than most other skills to boot), but standard options like Swift Sparrow and Atk/Spd Solo remain considerations for consistency.
