Selkie

I use Distant Counter + Distant Def on Selkie to help her take on mages, as she can already wipe dragons. Sabotage Atk is to make use of her Res, which is buffed by Odd Res Wave (I personally use Odd more than Even waves)

build name: FEAR THE RES !!

when brazens are on , her only weakness are bow, dague and strong brave axe

other those, she can tank everything thank to her +15 def and +22 res
and i'am not counting even res wave or sabotage atk

in short ; keep her away from rhaja, cherche, eir and bow lyn and you should do well

Fix your site Gamepress. This set shouldn't exist at all. Yet I'm almost certain it will go up unchecked. Adult Cavalry allows Selkie to breathe oxygen and Snuggle Time! You are he ocean's Gray Waves, destined to seek, life beyond, the shore, just out of reach when you're half asleep and hung over. Fireflood Balm+ accentuates her staff in her pants??? Heavy Blade definitely belongs on this low atk "staff" unit. What does Mystic Boost do again. Nobody cares. Staff Valor 3 Staff Valor 3 Staff Valor 3 Staff Valor 3. And her boots? are steel-toed. Yeah. Don't mess with Snuggle Wuggle Bungle Rub a Dub Dub. Fix your site.

Selkie is a cavalry unit with a high res, good attack and a lot of movility. Her Weapon works based on the res of selkie and the difference with the res of the foe unit.

The best is focus her build on improve her rest and Attack. Fury is a good skill that gives points to all the stats. But she has a slow HP so is better to stay on Fury 2 or get Fury 3 and a good healer close of her.

Desperation 3 and brazen atk/res 3 are good skills that works with fury as well. It allows Selkie to explode her weapon and the difference of res with the rival, improving the damage and allowing a double attack. Most of the times it will be a good insta kill.

Stats above include weapon, +Res (originally -HP) at +2 merges, +4 cavalry dragonflowers and S-rank summoner support.

The idea of my build here is to emulate her starting kit to an extent. Atk/Spd Push over Bond and Solo since as a Cavalry hero, she will want to take advantage of her 3 movement, but only when going for a safe kill. She'll also want to stay close to her allies, ideally some of them being beasts, for transformation uptime and those sweet buffs; so she doesn't lean one way or another in terms of positioning. She is player phase oriented however, so something like Swift Sparrow is acceptable as well.

In my case I have Kaden and Reyson, as beast units, supporting her.
Kaden runs Atk/Def Link (as opposed to his inherent Spd/Res Link, I'll get to this later), Goad Beasts, and the Drive Atk sacred seal.
Reyson runs Close Guard, as I don't have Ward Beasts, and I have the visible buffs covered so I don't find Fortify beasts necessary; Selkie wants to focus on melee ranged opponents anyway, though Drive Def or Res are decent options as well. I do have a non-Beast hero on the team (M!Corrin), so if Reyson ever finds himself without 3 movement, the Aerobatics sacred seal will give him some extra mobility there. Reyson's Heron Wing has a healing aura which is synergistic with Atk/Spd Push, effectively removing the necessity for a healer or other healing methods in any capacity.
M!Corrin has S-rank ally support with Selkie, so he can facilitate further buffstacking. He also runs Res Tactic to cover the last of the visible buffs, and the Drive Def sacred seal to help patch her paper thin defense. Mix and match your own buff stacking options as necessary.

The reason I opted not to use her inherent Sabotage attack, is mainly personal preference. I prefer to use skills that I have more control over; I can influence AI movement to an extent but it doesn't guarantee that the opposing heroes will stay huddled together or next to each other. Same goes for the other global debuff: Chills, one hero (potentially more) will be debuffed, but it isn't always going to be the one that I/you will want to take on first; if you find Chills helpful however, another hero on the team can run it instead. In my case, M!Corrin could opt out of Axebreaker, and run Chill Atk or Def. Dull Close may be niche, and sometimes ineffective, but it guarantees that Selkie's melee opponents can't make use of their visible buffs, which is key for when Foxkit Fang res checks; only visible (de)buffs to resistance influence this, not in combat buffs. Since she receives +6 resistance from visible buffs, she will effectively receive at least +3 to all stats from her weapon, since not many heroes can match, not to mention exceed, her resistance. Also wouldn't make much sense to be running a resistance debuff skill when I have no magic attackers on the team. Panic is also ineffective since Selkie's teammates are predominately going to be beasts, and beasts don't have high HP pools to be making use of it effectively. Aversa's, should you choose to use her, can be a decent support, so long as you don't fight armors or high HP heroes in general.

Selkie's C skill, aside from being a source of visible buff, is mainly there for aesthetic purposes, and as a result of what skill fodder I had available. I appreciate that I.S. gave her a skill with the title "Even" in it, as a reference to the Kitsune class skill Evenhanded, as opposed to the Wolfskin class skill Odd Shaped. If I had Even Atk Wave available or even Even Def Wave (heh double even), I would've stuck with Kaden's inherent Spd/Res Link; alas, this was not the case, but I did have a Sumia sitting in the barracks, so she was put to good use.
HP/Res 2 is there to pad her stats a bit more.

Another build option would be the tried and true Fury Desperation combo. If you're confident in your Selkie's attack, she can make use of the Heavy Blade sacred seal for faster charges and make better use of skills like Aether or Galeforce. In addition to simple stat modifying seals, Brazen Atk/Def or Res sacred seals would also work. Fury also plays nice with the Ploy set of C skills, as without Dull Close, Selkie herself no longer ignores the opponent's visible buffs.
