Healer A-Slots

Healers can use Bond and Brazen skills.

Brazen Atk/Spd is ideal for an offensive healer.

Fortress Def/Res

Weeeeeelll... I run Speed +3 on my Genny build because I can get her speed up to 43 consistantly (with buffs), which allows her to double/not be doubled along with her massive attack stat. If I put Brazen Atk/Spd she'd reach 43 speed (47 with buffs), and 57 ATK.

For Azama I use Fortress Defense, since he has no need of attack, speed, or resistance, really. Healers can also use the Boost skills, though they usually don't have enough HP to run them properly.

Defiant skills (and the Brazen skills) are actually really good on healers, since they most often run Miracle with an offensive build. If you had a Brazen Atk/Spd healer along with desperation, you could use it as a pretty good player phase.

Another surprisingly often used skill is Close Counter, since you can run a really sweet Pain+, Miracle, CC, Vantage, Savage Blow*2 setup.

Depends on what you're running. I have Mist as a 5* Healer (Why the hell is she a 5* pull?) and I have her with Slow+ and refined it with the "Enemy units cannot counterattack" option. As far as I could tell, all healers have two options as far as refinement. No counterattacking and dealing damage like normal. You could essentially give a healer the Wrathful Staff, and then refine the weapon with Dazzling (or whatever the name is) and then give the A slot skill as something that'd increase damage (or in Azama's case, decrease damage taken) but, again, it really depends on what you're healer is using as far as the weapon.

If you're trying to get an A-slot for a healer that isn't 5*, then I don't know if it's really worth it. Non-weapon-refined healers are, in my opinion, not necessarily worth investment, except for those cavalry healers I guess.

genny with atk +3 is terrifying. she can reach absurd amounts of atk and with pain+ deal at least 10 additional dmg on top of that without getting countered. She wont double, but you can use her high res to at least bait mages fairly reliably. The non budget version would be atk/res bond. Lissa and Azama could also use atk/def bond or close counter.
I'm not a fan of the new brazen skills. They rely on the unit being damaged which is hard to do, especially for a healer that shouldnt be on the frontlines and wont/shouldnt even get counterattacked.

this may sound dumb but hear me out you should use defiant atk 3 so since 5* heal skills depend on the Atk stat 7 extra attack for just being half health is pretty amazing...i gave my bride lyn defiant atk and ive never regret it

close counter
