Kaden

Weapon: Kitsune Fang (+Eff)

Assist: Positioning Assist / Flexible

Special:  Moonbow / Luna

Passive A: Fury / G Duel Cavalry / Triangle Adept 

Passive B: Link Skills / Even Pulse Tie 

Passive C: Distant Guard / Rouse 4 Skills / Drive Skills / Tactic Skills / Flexible

Sacred Seal: Drive Skills / Distant Guard / Spur Skills / Tactic Skills / Flexible

• Kaden’s best bet by far — and what he’s most known for —  is doubling down on the supportive aspects of his Kitsune Fang, with the stat swings and Guard effect he can distribute among nearby allies being quite impactful for defensive strategies (as this already lends itself to units bundling closely together). As he generally won’t be seeing combat, his choice of IVs don’t really matter beyond anyone seeking to stack HP to leverage Pulse Tie skills, in which case +HP should naturally be prioritized. 
• His Special and A skill here are… largely unimportant in the grand scheme of things, as Kaden’s should rarely be engaging combat outside of last minute clean-up duties. With that in mind, Moonbow and Luna are perfectly solid for their low base cooldowns, and both Fury and Triangle Adept work fine for generalist purposes while bearing generally minimal investment costs. 
• For anyone seeking to maximize Kaden’s scoring potential and/or ability to wield Pulse Tie, however, G Duel Cavalry becomes the prime choice, with its fourth-tier version even operating similarly to Fury without the detriment of sustained chip damage.
• For Kaden’s B skill, his options become a bit more diversified:
  • Link skills are a classic for support builds — and for good reason, as they immediately enable an effective +12 boost to your choice of two stats on affected allies stats given how Kitsune Fang works. The choice between which to use boils down to personal preference.
  • Even Pulse Tie stands as one of Kaden’s best supportive tools as well despite its lack of influence on his stat swings. Although it does require sizable investment into his HP, the +2 Special charge it applies to the foe with the lowest HP is well worth it to bypass pre-charged Specials, which are extremely prominent in all competitive modes. Combined with his Drive Guard effect post-refinement, Kaden can readily help subvert otherwise complicated enemy mechanics.
• The Kitsune Braggart’s C and Sacred Seal slot should typically be filled by some form of in-combat boost to build on the enhancements innately provided by his PRF, such as Distant Guard and Drive Atk. As for the visible buffs Kaden needs to actually maintain his effects, they should generally come from either Link skills or fellow support units so that both Kaden and the main carries receive them. 
  • To that end, it’s worth noting that Kaden pairs extremely well with Ashera during Astra Season in AR-O (as explained in his Strength section), particularly for access to the Null Panic buff — he can equip a Rouse 4 during Light Season to mimic this, but positioning restraints in many enemy maps make this unwieldy.

Weapon: Kitsune Fang (+Eff)

Assist: Positional Assist / Flexible

Special:  Moonbow / Luna 

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

Passive B: Near Trace Skills / Lull Skills / Desperation

Passive C: Joint Drive Skills / Tactic Skills / Rouse 4 Skills / Flexible

Sacred Seal: Swift Sparrow / Atk/Spd Solo / Drive Skills / Tactic Skills 

• Considering that refined Kitsune Fang potentially grants him a Spectrum +10/+10/+2/+2 and Guard (in addition to his transformation bonuses), Kaden may also opt for a more offense-tuned build as well to develop this Player Phase potential. To be clear, this is more of a “fun” build for anyone seeking for an alternative to his usual playstyle, as it can be pretty resource-intensive — and ultimately, he is better off as a support. 
• With that out of the way, Kaden’s primary gameplan here is to stack further offensive bonuses to serve as a reasonable source of damage output, making it best to seek +ATK or +SPD IV as well as a complementary Atk/Spd enhancing A skill. Among those available, Swift Sparrow, Atk/Spd Push, Atk/Spd Solo, and Atk/Spd Catch are some of his best candidates, though ultimately anything available can work in a pinch. 
• For his B skill, one may consider an available Near Trace or Lull for either greater mobility or stat superiority respectively, with both offering modest in-combat debuffs on foes. Desperation also works on a budget to ensure Kaden’s ability to engage in continued rounds of combat, regardless of how much damage he incurs. 
• Both his C and Sacred Seal slots are flexible and open to anything that operates either selfishly or supportively, altogether coming down to how much one is willing to invest in the fox’s performance within the context of this build.
