Spring Henry

Weapon: Reindeer Bow+ (+Def) / Tannenbow+ (+Def) / Plegian Bow+ (+Def) / Sunflower Bow+ (+Def) / Spendthrift Bow+ (+Def) / Courtly Bow+ (+Def) / Carrot-Tip Bow+ (+Def)

Assist: Positional Assist

Special: Bonfire / Ignis

Passive A: Close Foil / Close Reversal / Close Counter

Passive B: Lull Atk/Def / Quick Riposte

Sacred Seal: Quick Riposte / Atk/Def Solo / Atk/Def Form / Atk/Def Bond / Shield Session / Sturdy Stance / Close Def

• Unlike the Ruse support build, this build focuses resources on building up Henry's physical tanking more selfishly. A lot of elements do transfer over though with a simple goal: utilize a weapon and all passive slots possible that improves his physical tanking capabilities.
• To make good use of Henry's standout Def, running a close-countering skill gives him leverage versus a multitude of melee units. Close Foil and Close Reversal are generally your best choices as they add relevant extra stats in combat. 
• Additionally, to account for a lack of additional combat effects in close countering skills, Henry should compensate with a weapon with good effects. Reindeer Bow+, in particular, would be best as it's very accessible from Heroic Grails and comes with Special denial (aka Guard) — something Henry values to help prevent himself from getting blown away by enemy Specials. Similarly, Tannenbow+ is accessible from Grails and grants a form of penalty protection by reversing any Atk/Def debuffs that comes Henry's way.
  • There are also a ton of bows that are very similar to these ones with various useful effects. In a nutshell, Plegian Bow+ grants penalty doubling, Sunflower Bow+ is basically budget Spendthrift Bow+, Courtly Bow+ offers first-hit damage reduction, and Henry's default Carrot-Tip Bow+ gathers all enemy penalties into a single powerful first hit. 
• We swap out the default Ruse skill for a more direct combat skill, and Henry's ranged cavalry status pretty much cuts this to two options: Lull Atk/Def cancels out existing enemy bonuses and further cuts down those two stats by -3. Meanwhile, Quick Riposte helps Henry secure kills by adding a guaranteed follow-up. It's recommended to have Quick Riposte at least somewhere on the build — whether it be through the Sacred Seal or B-slot — for that reason.
• There's a variety of C-slots that aid Henry's tankiness. Atk Smoke, for instance, is easily available at low rarity and applies a widespread debuff after finishing one combat. Atk/Def Menace automatically buffs Henry and debuffs a nearby enemy within four spaces, making it a preferred and more potential, passive option. Finally, if you're grabbing Close Reversal from Gatekeeper, might as well leverage Joint Drive Def from him as a solid option that benefits both Henry and nearby allies.
• If you aren't already using Quick Riposte as the Sacred Seal, this slot is open for a number of great choice to top off Henry's tankiness. Depending on your preferred phase or positioning requirements, this ranges anywhere from Atk/Def Bond, Form, Solo and other similars. 

Weapon: Brave Bow+

Assist: Positional Assist 

Special: Bonfire / Luna

Passive A: Death Blow / Atk/Def Catch / Atk/Def Push

Passive B: Lull Atk/Def / A/D Far Trace / Chill Def

Passive C: Rouse Atk/Def / Joint Drive Atk / Def Smoke

Sacred Seal: Death Blow / Atk/Def Solo / Blade Session

• We're definitely not inspiring a grand spring of creativity with a simple Brave Bow+ build, but it does work out in the end thanks to the weapon's strong hits per strike from Henry's great Atk and essentially turning Henry's weird Spd into a total nonissue. 
• At the end of the day, it's the same song and dance: bolster Henry's Atk as much as possible with direct passive skills like the cheap and accessible Death Blow (or Atk/Def skills if you want bigger and and fancier Bonfire numbers) for strong player phase hits, and keep Henry away from absolutely any semblance of enemy phase whatsoever as Brave Bow+ negatively lowers his performance there.
• Several B-slot skills help tremendously with additional damage output. Lull Atk/Def is usually the best choice since it cancels out any existing Def bonuses on the enemy while applying an additional -3 debuff as well. If you're not worried about the enemy buffing their own Def specifically, A/D Far Trace instead grants 【Canto (Rem.)】, which can provide a neat means of escape after Henry is done with combat or some other action. Lacking or not willing to give these, Chill Def is a more accessible option that applies a pretty sizable -7 penalty automatically; in optimal conditions, we're looking at +14 additional damage.

Henry's C-slot ideally should follow the same goal as the others: buff Henry's offenses in some way. There's many ways to do this from Rouse to Menace to Smokes; as long as it involves Atk or Def or both, choose which suits your level of investment.

Weapon: Carrot-Tip Bow+ (+Def) / Plegian Bow+ (+Def)

Assist: Rally Def/Res+ 

Special: Bonfire 

Passive A: Close Foil / Atk/Def Solo / Other Atk/Def Skills

Passive B: Atk/Def Ruse

Passive C: Atk Smoke / Atk/Def Menace / Def Smoke

Sacred Seal: Atk/Def Solo / Quick Riposte / Atk/Def Bond / Atk/Def Form / Sturdy Stance

• Since by default Henry comes with Rally Def/Res+ and Atk/Def Ruse, he can play his intended role as a buff/debuff bot. This, by itself, is a pretty simple task: simply rally a teammate in a cardinal position so that their stats are fortified while Atk/Def Ruse inflicts some nasty Atk/Def debuffs and Guard on priority targets. 
• Because Atk/Def Ruse allows Henry to manually apply Atk/Def penalties to any enemies you want in cardinal positions, there are a couple of bows that take precise advantage of this:
  • Henry's default Carrot-Tip Bow+ already enforces the playstyle the developers had in mind for him. Specifically, the total existing Atk/Def penalties on the enemy gets added to the bow's first hit, and Henry also gains an appreciative Atk/Def +5 on top of this. Since the Def debuff is basically counted twice over (as visible and in-combat stats factor separately) and this is added ON TOP of whatever damage Henry's already dealing, expect some solid single-shot damage from the bow's first hit. Overall, it's pretty useful for a default weapon and does exactly as the build intends.
  • Plegian Bow+ fits Henry's lineage to a T and also happens to benefit from Atk/Def Ruse specifically. Similar to Carrot-Tip Bow+, it counts any existing Atk/Def penalties on the enemy and instead essentially doubles them in combat. Basically, it's a more stable defensive option that serves to bolster Henry's general combat in favor of Carrot-Tip Bow's damage focus. It does require Henry to be separated from his allies, but this is a pretty easy condition to uphold and can be fortified with other Solo skills, all things considered.
• Henry's A-slot skill should be focused on further improving his physical talents. Close Foil, for instance, grants him a handy boost Atk/Def +5 while also enabling him to counterattack physical melee enemies up-close. Other close counter variants can be taken as long as you keep away from the functionally useless Ward line. Lacking these, you can keep Henry exclusively to ranged counterattacking with a variety of Atk/Def skills such as Atk/Def Solo. 
• Since Henry's Spd is not the best, it's a good idea to consider Quick Riposte to ensure better damage through a guaranteed follow-up in enemy phase. Else, the Sacred Seal's also open for Atk/Def bolstering skills like in the A-slot.
• In the C-slot, though Atk/Def Menace may seem redundant when Atk/Def Ruse is already in use, it does save Henry the effort of manually debuffing the enemy by automatically applying them instead on a foe within four spaces. Generally, this allows Henry to be more flexible with his actions than simply Rallying and mobilizing. Else, you can simply run Atk or Def Smoke as more accessible alternatives to really lay on the pressure and penalties.
