Corrin (M)

Weapon: Yato (+Eff)

Assist: Positional Assist

Special: Moonbow / Glimmer / Ruptured Sky

A Passive: Fury / Life and Death / Still Water / R Duel Infantry 4

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

C Passive: Inf. Null Follow / Joint Drive Atk / Spurs

Sacred Seal: Distant Guard / Close Guard / Spurs / Fury

• Corrin’s Yato effect weapon is unique in the sense that it grants a visible stat boost to all stats. This can potentially allow Corrin to be the soaker of Chills and the Shrines in Aether Raids Offense as those skills/structure targets the enemy with the highest visible stat on the opponent team. 
• The player can choose to run visible stat-boosting Passive A in order to exceed the unit that he is supporting. Fury provides the most all-rounded stat boost, while Life and Death and Still Water provide a more targeted stat boost to potentially outmatch the units they wish to support. R Duel Infantry provides a slightly small all-rounded boost, but it has an additional HP + 5 that could be used to meet HP checks from skills such as Even Pulse Tie and Sudden Panic. If required, Corrin can also run stat boosting seal such as Fury if one needs more visible stats to soak the debuffs.
• The rest of the kit simply focuses on his ability to provide support in another manner. If Corrin is used in conjunction with an Infantry tank, Corrin can use the new Inf. Null Follow to provide his partner with Null Follow-Up, which opens up the Passive B for the tank in favor of damage reduction skills such as Spurn, or other utility skills such as Null C-Disrupt, Lulls or even the new Bulwark skills. Alternatively, any in-combat support such as the likes of Joint Drives and the Guard skills can also be used. Lastly, Save balls can also opt for Spurs, and unless your Far and Near Save unit are literally the same unit, Yato only works on one ally.

Weapon: Yato (+Eff) / Coral Saber (+SPD)

Assist: Positional Assist

Special: Ignis

A Passive: Atk/Spd Unity / Spd/Def Ideal / Atk/Spd Form

B Passive: Null Follow-Up / Lull Atk/Spd / Atk/Def Bulwark

C Passive: Joint Drive Atk / Joint Drive Def / Spur Atk/Res

Sacred Seal: Steady Breath / Darting Breath

• Due to being an Infantry, Corrin can also be used as a makeshift melee specialist due to having abundant choices in terms of the Passive B slot. However, compared to modern weapons, Yato might lack the combat boost required to perform in the meta. A player can probably replace his weapon with generics such as Coral Saber should a player want to focus on his combat rather than his stat-boosting utility for his Far Save unit, although that would not make him that much different compared to other melee specialists.
• The rest of the kit is primarily focused on being a melee specialist by doubling the foe and taking the foe out with an Ignis activation. Corrin would need to juggle between cooldown acceleration, having enough DEF to take hits and having enough SPD to double the opponent.
