Halloween Robin (M)

Weapon: Moonstrike Breath

Assist: Positional Assist / flexible

Special: Bonfire / Glimmer

IVs: +Atk or +Def / -Spd

Passive A: Sturdy Stance / flexible

Passive B: Slick Fighter / Dragon’s Wrath / Dragon Wall / flexible 

Passive C: A/R Near Save / A/D Near Save

Sacred Seal: Steady Breath / Atk/Def Bond / flexible

• Robin’s stats, movement type, and weapon lend him well to a Near Save build. 
• With Steady Breath seal, Robin can take one hit and then immediately charge a 3-cooldown Special like Bonfire to activate on the counterattack, which will also heal 30% of his maximum HP when it hits from Moonstrike Breath. This can KO a huge percentage of units in a single hit, barring those with extremely high defensive stats or some kind of percentage-based damage reduction such as Fallen Star, or those that slow Special charge with skills like Guard. He can also opt for a stat-boosting seal like Atk/Def Bond or Atk/Def Form and a 2-cooldown special like Glimmer to a similar effect, but the damage is less reliable compared to Bonfire. Robin can also opt for a healing Special such as Noontime or Sol, but this extra healing is often less useful than the extra damage from one of the aforementioned Specials. 
• The two most important stats for a Near Save unit are Atk and Def; Def to survive attacks from physical units, which make up the vast majority of threatening melee units, and Atk to KO on the counterattack. As such, his best boon is one of those two stats. -Spd is a safe choice of bane in general, as Robin’s Spd is terrible and generally not of use. 
• Sturdy Stance 3 is a great choice of A slot that boosts Robin’s Atk and Def by 6 and reduces his foe’s Special charge gain by 1 when the foe initiates combat. This Guard-type effect is very useful for preventing the activation of enemy specials, but the skill can be substituted out for another if more stats or another effect are desired, such as Close Def 4 for its enemy buff nullification. 
• Slick Fighter is a great B slot, which neutralizes Robin’s penalties and guarantees his follow-up attack if a foe initiates on Robin while he is above 25% HP. He also has other good options such as Dragon’s Wrath, which both reduces the damage Robin takes from an initiating foe’s first Atk by 20% as well as increasing his damage by 20% of the advantage his Atk has over his foe’s Res, increasing his ability to one-shot many units but leaving him vulnerable to a second hit if he fails to KO in one hit. Dragon Wall provides a larger potential damage reduction at 40%, but it depends on Robin having higher Res than his foe, up to the full 40% damage reduction if his Res is 10 higher than his foe’s. 
• Near Save is the crux of this build, allowing Robin to protect allies within two spaces when melee enemies initiate combat against them. His base A/R Near Save works well, while A/D Near Save gives arguably a better combination of stats against most melee units (with the exception of dragons), though it is not a huge difference in effectiveness. 

Weapon: Moonstrike Breath

Assist: Positional Assist / flexible

Special: Bonfire / Glimmer

IVs: +Atk or +Def or +Res / -Spd

Passive A: Distant Counter

Passive B: Slick Fighter / Dragon’s Wrath / Dragon Wall / flexible 

Passive C: A/R Far Save

Sacred Seal: Steady Breath / Atk/Def Bond / Mystic Boost / flexible

• Robin can also effectively use A/R Far Save to protect allies from ranged units. The specifics of this build are very similar to the Near Save build, except that it also requires Distant Counter for Robin to counterattack ranged units, and Res-boosting skills like Atk/Res Bond are more useful. Mystic Boost seal is also a solid choice for providing after-combat healing and disabling the Wrathful effect of Staves and adaptive damage.
