Best unit for Warding Breath?*

Unfortunately, Fjorm and dragons would be the best pick for it, since Fjorm and Fae (who is heard is the better for the skill) have good Mage tanking abilities.

It’s too bad we can’t put it on archers or daggers. I’d put that on Innes in a heartbeat. ;-;

Dorcas might be a good alternative to dragons, his resistence can go pretty high thanks to that skill (especially if he's +Res since he gains four points) but he can't counter attack against B!Lyn.
Any infantry/armored unit with good bulk and weapon with distant counter is the best option to get the best of Warding Breath's potential.

My Dorcas is +Def/-Res so it would kinda be a waste to give him that skill (I couldn't get any LIke during the event anyway).

I used them on Nowi as well as my -HP+Res Zelgius. I see it as an alternative to any current meta steady breath users, just the resistance version.

*cough cough

We don't really know what unit we're getting at the moment. This is only the first round, and it seems like people are wanting L!Ike, Hector, and W!Tharja, so it might be too early to really determine units for a skill from a unit you possibly won't be getting.

maybe joshua? he can take physical and magical damage decently well, and with his weapon has more res, plus a special cooldown built in for more special triggers

edit: never mind. he doesnt have a distant counter built in so this wouldnt be a very good idea.
