Cain

Cain's new blade can make him very tanky while being a brave sword monster with his unique refinement. Since his refinement and base effect encourages him to stay close to his allies, running double Atk/Def bond 3 is a solid option while Mystic boost 3 keeps him healthy after every encounter.

~Red Hussar~ [WIP]

Budget OG cav sword waiting on refine and Fury. Would like to make him speedy dual phase centered around WoM but he's been low priority (blame Xander/Sigurd/Siegbert)

{Cain = Eldigan + Brave Roy}
As the description above says, this build aims to make Cain an extremely bulky unit while retaining an offensive spread that is only slightly weaker than Brave Roy's. Before the weapon refinery update, Cain's stat spread was nothing special. An offensive spread of 32/32 is decent but 27 defense is just "meh". Now with the ability to upgrade weapons, Cain's stat spread went from decent to extraordinarily good.
Like I mentioned previously, this set aims to make Cain very bulky while retaining an above-average offensive spread. With slaying edge (+def), Cain's defensive spread shoots up to 44 hp and 31 def on top of 49 atk and 35 spd. To put this into perspective, one hone and one fortify cavalry means that his stat spread when he initiates combat skyrockets to 44 HP/55 atk/41 spd/41 def/27 res.
The reason why Bonfire is chosen is because Cain can get an extra 20 damage when he initiates combat with horse emblem buffs and is a better option than Luna, even without horse emblem buffs. Sturdy Blow is a good A slot since it ensures that Cain hits hard while still being able to tank hits well. Armored Blow is also an option but he will not be as hard hitting in exchange for more tankiness. Swordbreaker is a great skill for him as he cannot outspeed too many sword units, but can still one shot squishy archers and mages. Hone cavalry is self-explanatory but other cavalry buffs will do just fine. An atk seal, spd seal, or a def seal all work great with this set. Swap is great for tanky melee units such as Cain who can take a hit for one of your allies. Reposition can also be considered for an assist skill.
As powerful as this Cain is, he still remains relatively weak to mages. Although he will most likely not die to many due to his high speed and high hp, he will eat a lot of damage and be knocked out of Swordbreaker range.

In a game full of Sword Cavaliers with legendary weapons, who can help a Summoner's dream of having a Wo Dao cavalier come true?

Look no further than Cain, the Bull. Possessing good mixed stats that can be emphasized in a Horse Emblem team, this build focuses on amplifying his Atk and doubling enemies in order to get a charged Moonbow off in the same round of combat. While his Def and Res are lackluster compared to some other potential duelists (e.g. Def+ Mathilda), Cain's Spd and Atk stat make up for his defensive shortcomings by preventing most units from doubling him without their own Spd buffs or Swordbreaker.

Wo Dao+ with a Spd emphasis are used to increase Cain's offensive power while keeping his Spd high enough to enable doubling with the help of Darting Blow 3 and Hone/Goad Cavalry. On initiation, he boasts 41 Spd without Hone Cavalry; with them, this stat increases to 47, along with a fearsome 55 Atk stat.

Draw Back is the typical support skill for my Duelist archetype, allowing a duelist to protect a healer or nuke from harm, or pulling a tank into position to absorb a few hits.

Moonbow has the best synergy with Wo Dao+, though both Glimmer and Daylight were considered for the role. Glimmer could be taken for a riskier increase in damage, while Daylight increases Cain's sustainability.

Darting Blow was primarily chosen to help increase Cain's matchups- the A slot is largely up to the user's choice, and other suggested skills include Steady Stance for a more defensive duelist or Swift Sparrow for increased power.

Wings of Mercy is excellent for surprise attacks that leave a foe reeling and discombobulated, but again, B slot is also largely up to a Summoner's preference.

Fortify Cavalry is the final straw used in my personal Duelist archetype, allowing all other heroes in a Horse Emblem team to receive a defensive buff while allowing the Duelist to still obtain the offensive Hone that allows their Atk and Def to soar.

Note: This Cain(The Annihilator) is +3 and his stats are already added by equipment. If you want his base stats, minus the numbers in yer head.

I submitted the original Cain build of mine already, so a lot of the notes you can get from there; this is a variant of that.

I change two things for this Cain, and I do so sometimes when I feel necessary for random battles based on events, though I will say the Brave Sword build is the best set for using Galeforce.

Two changes, weapon and special. He now has a higher attack with speed that is as it should be, not negated by Brave Sword. Because of this he no longer needs to worry about activating Desperation, and can even do so easier since he doesn't need to be 50% health for Brash Assault. Mix him in a horse team, and his destructive powers increase further.

With his stats being as high as they are for attacking purposes, activating Luna will allow him to kill almost anything, more so securing a kill when he attacks on the 2nd time; even blues. He activates Luna with a 2 turn charge because of the Slaying Edge+ and it's nature of reducing charge by 1.

Note: Seal is Brash Assault 3

While I could change this, I simply like guaranteeing absolute death just in case I run into someone with higher speed in melee combat.
