Fae

Weapon: Eternal Breath (+Atk)

Assist: Positional Assist

Special: Moonbow / Glimmer

A Passive: G Duel Infantry 4 / HP+5 / HP/Res 2

B Passive: Sudden Panic / Even Pulse Tie / Sabotage Atk

C Passive: Canto Control / Inf. Null Follow / Infantry Pulse

• Fae’s main niche is her ability to provide visible bonuses to all stats. This can be useful as a support unit in both Aether Raids Offense and Summoner Duels. The focus of the build is to provide support on top of her weapon’s usual effects. As an Infantry unit with a rather significant HP value, Fae poised herself with the ability to provide HP support, such as either for allies with the likes of Infantry Pulse or inflicting debuffs such as Even Pulse Tie or Sudden Panic.
• The choice of C Passive is largely dependent on which mode would Fae be used. In Summoner Duels, Canto Control is likely the best form of support to prevent hit-and-run attempts on her allies, while it is likely that Aether Raids Offense would prefer other support such as providing Null Follow-Up support with Inf. Null Follow. 
• The rest of the build rounds out her niche further by ensuring that she meets HP checks. G Duel Infantry 4 provides the most stats on top of providing the HP, while HP boosting skills can also be used on a budget. If a player is opting for Sabotages instead, consider Res boosting skills such as Fortress Res. instead. 
• The choice of refining is largely inconsequential, with stat refining being prioritized over special refine due to having a higher HP value. One could go for the special refine, however it is unlikely to be useful as Fae would likely be taken out in single combat with a support-oriented build.

Weapon: Eternal Breath (+Eff)

Assist: Positional Assist

Special: Glimmer

A Passive: Atk/Def Unity /  Atk/Res Finish / Distant Stance

B Passive: Dragon’s Wrath / Dragon’s Wall / Atk/Def Bulwark

C Passive: Joint Drive Atk

Sacred Seal: Atk/Def Form / Distant Counter (D)

• This build focuses on taking the foe out in a single hit. Due to Fae’s relatively low Spd compared to the modern competition, Fae is likely reliant on taking the foes out before the foe can retaliate. One possible issue is the increased prominence of Miracle effects such as the likes of Ascended Celica and Brave Seliph. 
• Dragon’s Wrath provides Fae with the damage boost. On top of Eternal Breath’s cooldown acceleration on foe’s attacks, Fae can charge up Glimmer from foe’s attacks, and likely take the opponent out in one hit. The rest of the build revolves around providing Fae with enough Atk boosts to increase the scaling of Glimmer and Dragon’s Wrath. Bulwark skills are also decent options to allow Fae to protect her allies and stack more support, although it is likely that Res-based Bulwarks are ideal. 
• For a more defensive option, Dragon’s Wall is also a decent option due to Fae’s decent Res and high HP, however, it is worth keeping in mind that Dragon’s Wall is weak against skills such as Deadeye and Lethality.
• Whether to counter against ranged units is also dependent on the mode; it might be worth countering ranged units if a player is opting for a super-unit strategy in Summoner Duels, while in Aether Raids Offense it might be a better idea to opt for a melee specialist approach and leverage on a Far Save unit instead.
