Halloween Henry

• Preferred IV: +ATK or +SPD / -HP
• Weapon: Gronnowl+ (+Def)
• Assist: Swap / Reposition
• Special: Iceberg / Glimmer
• Passive A: Close Counter / Fury 
• Passive B: Vengeful Fighter / Quick Riposte / Vantage
• Passive C: Armor March / Varies
• Sacred Seal: Atk Ploy / Atk Smoke / Armored Boots

This set focus on Henry's main strengths: his good investment in speed and his adequate bulk.

Henry has very good resistance and decent enough defenses to run an Owl build very well. Coupled with Spur Seals and Armour Buffs, Henry can output ridiculous amounts of power while retaining good amount of bulk to take damage. Close Counter enables Henry to service as an all-rounded enemy phase unit, while the budget option Fury functions as a pure stat steroid against ranged units. Vengeful Fighter, though expensive, helps ensure he doubles the fastest of mages and speedy tome users will find it difficult to hit him twice over the owl boosts. Henry is also guaranteed to activate Iceberg in the second counterattack due to the additional charge from Vengeful Fighter. Quick Riposte and Glimmer are obvious substitutes for Vengeful Fighter and Iceberg if one does not have Vengeful Fighter fodder to spare.

The remaining portion of the builds are not integral to Henry's build. However, a special mention goes to Atk Ploy as Henry can leverage it very well with his high resistance stat. If Henry is not used in an armored team context, he can consider running armored boots to help his mobility.

• Preferred IV: +SPD / - HP
• Weapon: Spectral Tome+ (+Spd)
• Assist: Swap / Reposition
• Special: Iceberg / Glacies
• Passive A: Fury
• Passive B: Windsweep /Wary Fighter 
• Passive C: Armor March 
• Sacred Seal: Atk Smoke / Phantom SPD 

This build focuses on safely activating the effect of Spectral Tome.

Henry does have the speed to run a set that focuses around Windsweep. As Halloween Henry prefers not to take physical damage, running Windsweep allows Henry to safely engage on those enemies and activate the panic effect.  This is further augmented with speed refinements and Fury in the A slot.

The choice of seal is up to user preference. Atk Smoke has great synergy with Windsweep as Henry can activate it along with the Panic Effect. Phantom SPD is also not a bad option to increase the reliability of Windsweep.

• Preferred IV: +DEF / -HP
• Weapon: Gronnraven+
• Assist: Swap / Reposition
• Special: Iceberg / Glacies
• Passive A: Distant Def / Triangle Adept / Fury 
• Passive B: Vengeful Fighter / Quick Riposte /G Tomebreaker 
• Passive C: Armor March / Varies
• Sacred Seal: Distant Def / Armored Boots

This is a self-explanatory Raven set that focuses on countering archers and blue mages.  Henry does have great magical bulk and decent physical bulk which makes him an excellent candidate for such a build.

While Triangle Adept might seem to be the most intuitive build, with Firesweep bow are becoming increasing prevalent with Cancel Affinity, it might be worthwhile to go with the Distant Defence alternatives instead. With both the sacred seal and A slot, Henry can easily survive an engagement from both archers and blue mages while charging his special for a following turn OHKO.

This is another build that can work for Henry when he is the sole armor on a team. For such situations, Armored Boots can be considered to improve his mobility.

• Preferred IV: +ATK / -SPD
• Weapon: Gronnblade+
• Assist: Swap / Reposition
• Special: Iceberg / Glacies
• Passive A: Death Blow / Close Counter
• Passive B: Bold Fighter / Quick Riposte / Vengeful Fighter / Vantage 
• Passive C: Armor March
• Sacred Seal: Attack +3

Henry can also run a typical Blade Tome set that specifically tries to burst attackers down in a single exchange. Armor buffs are as potent as their Cavalry and Flier counterparts, making a Blade Tome based strategy viable. Henry's Armor March and the newly introduced Bold Fighter also allow Henry to be slightly more proactive in his player phase, guaranteeing doubles on most units if he initiates. Death Blow makes the most sense for a player-phase oriented build since Bold Fighter ignores Henry's SPD.

In order to utilize Henry's relative balanced defensive stats though, Close Counter with either Vantage or Quick Riposte (and Vengeful Fighter) is a good choice to switch into an enemy phase play-style, or if you want him to be a hybrid unit that works on either phase (albeit with less effectiveness in general).
