|This build aims to make Seth a physical green counter based around his base kit and solid Def stat.
We keep his default Ruby Sword+ to effectively wall green units (although green mages will still pose trouble due to his subpar Res). Players should be wary of any green units running Cancel Affinity 3 though (eg. Uncommon variants of Hector), as this skill will nullify Seth's effectiveness against green units and also cause him to take neutral damage back.
His default Swap is also fine to keep as it allows him to switch positions with an ally and put himself in the heat of battle to tank an enemy if needed.
For his special, we utilize his solid Def and take Bonfire. With a neutral Def stat, this nets him an additional 16 Dmg when Bonfire procs.
It is recommended to use Fury 3 for the all-around stat boosts to both his offenses and defenses.
For his B passive, Quick Riposte 2 allows Seth to retaliate twice against an enemy regardless of his own Spd. While his Spd is not completely terrible, it is still fairly low in a speed dominant meta. Quick Riposte also allows him to charge and ready Bonfire more quickly as well. Alternatively, a player can take Swordbreaker 3 to give Seth the ability to tank speedier Red Swords as well alongside green units.
Both his C passive and Sacred Seal are flexible depending on what Seth himself or his teammates need, although seals bolstering Seth's tanking ability are solid seals to take.
