Special builds for Ephraim - How to solo like a pro

I think picking a special might be the most important thing.

There are three I think work well.
Galeforce, Aether and Glimmer.

Here are some builds.
IV's are listed in order of preference

Galeforce:
Basicly, the same as Effie just with his own lance.
This build makes the easiest use of the solo skills, since you have to try putting him next to allies.
Skills: Galeforce, Atk/def Solo, Bold Fighter, Armor Boots
IV's: +atk / -spd -hp -res -def

Glimmer:
The idea with this is that Ephriam can shoot off glimmers with every counter attack. And with his mosterous atk, he oneshots a LOT of units.
Wary fighter is a good skill since you'll be banking on that one shot. It's a safety measure for units with desperation, or units that happen to survive the blast.
It also allows you to use the glimmer blast on ranged units even if you lack DC, by baiting then and killing on the turn after
Skills: Glimmer, DC or Atk/def solo, wary fighter, Fierce stance or either defence skill
IV: Atk+ Def+ Res+/ Spd- Hp-

Aether:
A bit of a standard one, but with the slaying effect and massive stats, Ephraim can sustain himself quite well.
There are a lot of ways to build him with this, but I'm just gonna take one option. I do like this build a bit less, I think Hardin is the lance armor you want for mixed phase sustain, given he comes with a DC weapon.
I won't surgest DC for Ephraim, since it spreads him pretty thin, skill wise. He needs the special cooldown.
Skills: Aether, Steady or Warding breath, Bold Fighter, Quick Riptose or Close Defence
IV: Def+ Res+/Spd- Hp-
