Sacred Seal: Atk/Spd Solo / Heavy Blade / Blade Session

• Panne can follow the standard protocol for a 2022+ offensive cavalry unit: utilize her great movement to close in on enemies, attack, and retreat back with the post-combat movement offered by S/D or A/D Near Trace (or Hit and Run on a budget). Thanks to the various perks offered by Taguel Fang, especially the spectrum stats, Guard, Impact effect, and automatic follow-up, Panne's initiations also tend to be very safe and powerful.
• High-grade Atk/Spd swinging skills in the A-slot and Sacred Seal improve Panne's offenses and hit-and-run reliability. As long as the skills chosen are player-phase friendly like Atk/Spd Solo, Atk/Spd Catch, and the Sparrow series, most will do. Surge Sparrow, in particular, synergizes immensely with Taguel Fang, making initiations almost completely risk-free thanks to its healing on Specials and keeping Panne above the weapon's full 25% HP conditional.
  • The only exception to this is if you're using Heavy Blade to quicken the trigger rate of Galeforce. That may be a heavy tradeoff, however, due to Panne's lower Atk disallowing her from confidently beating Atk checks sometimes. Regardless, when successfully done, Panne can go in for another attack and utilize the newly-refreshed movement for a complete retreat via Near Trace.
• The C slot is open for a variety of self-strengthening options. 
  • Rouse skills, in particular, encourage Panne to upkeep her transformation conditions by staying away from other allies. 
  • Menace skills are less positioning reliant — as close contact with other allies is sometimes an inevitability — and debuffs a neaby enemy in two chosen stats as a nice secondary effect for a total stat swing of +14 each. Any Atk-based Menace especially aids in meeting Heavy Blade checks.
  • Smoke skills inflict helpful stat penalties on the enemy after combat, and if you can get their fourth-tier variations, Panne greatly benefits from added secondary effects, including Speed-based damage reduction (Spd Smoke 4) and follow-up denial (Atk Smoke 4). On a budget, their third variations are perfectly accessible from low-rarity units and still helpful where it counts in combat. Def Smoke is a default on Panne that allows her to deal more damage, especially after triggering Galeforce or being Dance'd into another action.

Weapon: Taguel Fang

Assist: Reposition / Swap / Draw Back

Special: Moonbow / Noontime / Sol

Passive A: Atk/Spd Solo / Atk/Spd Catch / Distant Dart / Distant Stance / Distant Counter / Kestrel Stance 3 / Spd/Def or Spd/Res variations of listed skills

Passive B: Lull Atk/Spd / Lull Spd/Def

Passive C: Spd Smoke / Atk Smoke / Joint Drive Atk or Spd / Atk/Def Menace / Atk/Spd Menace / Spd/Def Menace 

Sacred Seal: Atk/Spd Solo / Spd/Res Solo / Spd/Def Solo / Mystic Boost

• Of course, we can't leave the horse barn without mentioning the cavalry class's access to Lull skills, the Spd-based variety of which suits Panne perfectly as they cancel Spd bonuses on her opponent and make her Spd-conditional guaranteed follow-up easier to fulfill. Besides this, Lull skills are also Panne's best B-slot choices for a mixed-phase skillset, which Panne can run reasonably well due to her well-padded out defenses after considering Taguel Fang's effects.
• Besides the choice of Lull skill in the B-slot, a few differences arise here compared to the offensive builds. Specifically, as this build is geared towards survivability and incoming combat, skills that grant healing, increased defenses, and dual-phase flexibility are favored. 
• Since Panne's guaranteed follow-up effect and an additional Atk/Spd/Def/Res +4 lie on Panne keeping herself above 25% HP, it's in her best interest to have some form of healing prepared. If outsourced forms (dedicated staff teammates, Sparkling Boost, Reyson/Leanne's passive healing, etc) aren't an option, you may consider running Noontime, Sol, Mystic Boost, or some combination of these to keep healthy.
• The usual A-slot and Sacred Seal recommendations apply, though we favor Solo and Catch for their ability to work in both player and enemy phase. For ultimate counterattacking flexibility, running some sort of Distant Counter variation in the A-slot allows Panne to take on ranged enemies as well. 
  • Distant Dart is preferred above all else for its Spd increased factor, and unlike Distant Pressure, it does not inflict recoil. The only disadvantageous factor about it is that it merely pigeonholes Panne a bit more into enemy phase. 
  • For more Res bulk, Distant Stance is a good choice as well.
• Since Panne will likely see herself in the thick of battle without a Canto movement effect to fall back on, a Smoke skill of choice allows her to take on nearby mobs of enemies easier. Spd Smoke 4 highly grants Spd matchups in her favor while fortifying her bulk further with Spd-based reduction, making it a preferred C-slot choice. Else, Atk Smoke or some Menace skill of choice will perform almost as well.

Assets/Flaws: +SPD &/OR +ATK / -HP

Weapon: Taguel Fang

Assist: Reposition / Swap / Draw Back / Ardent Sacrifice 

Special: Moonbow / Luna

Passive A: Swift Sparrow 3 / Surge Sparrow / Atk/Spd Catch 4 / Atk/Spd Solo 

Passive B: Windsweep / Watersweep / Desperation

Passive C: Fatal Smoke / Rouse Spd/Def / Atk/Spd Menace / Rouse Atk/Spd / Atk/Def Menace / Spd/Def Menace / Atk Smoke / Spd Smoke

Sacred Seal: Atk/Spd Solo / Blade Session

• Not much really changes here from the other Player Phase build; Panne still uses the usual Atk/Spd boosting passives to strengthen herself, whichever C-slot skill help her hits bite harder, and a short-charged Special like Moonbow for reliable burst damage, all stacking with the goodies that come packed in her weapon. 
• What fundamentally differentiates this build, however, is the choice of B-slot involved. Because Taguel Fang grants a guaranteed follow-up attack if Panne bests her opponent in Spd, Panne can run a Sweep skill of your choice to prevent counterattacks from your preferred group of targets. Your choice lies between Windsweep to safely assault physical enemies, while Watersweep might be an attractive alternative to handle Panne's usual countermeasures, those being magic and dragon enemies.
  • Note that most mages don't run Close Counter nowadays, and Panne doesn't get certain bonuses by attacking dragon foes, making Watersweep sometimes a somewhat stunted option compared to Wind. 
• The magic of Taguel Fang and your chosen Sweep skill lies in Panne still maintaining her follow-up, assuming she 1) meets the 5 Spd requirement of a natural follow-up attack, and 2) the opponent doesn't have follow-up denial effects of their own. 
  • Even if conditions aren't exactly optimal, Panne can also still fall back on the Impact and Guard effect of Taguel Fang as preventive measures to powerful punishment. 
  • Note that no matter which type of Sweep skill you use, as long as Panne bests her enemy by 5 Spd, she will still manage to maintain her follow-up hit regardless of the enemy's weapon type.
  • Alternatively, if you're confident you can set up Panne safely (perhaps through safe initial matchups or Ardent Sacrifice), Desperation is a nice budget option that allows Panne to make safe double hits; she is likely to make her kill before being retaliated against. Unlike the Sweep skills, however, it doesn't totally prevent counterattacks if Panne DOES fail to kill within two hits, and Panne will have to keep herself within a sweetspot between 25-75% to make the best use of Desperation and all effects present in Taguel's Fang.
