So I have a +1 Soren that's +Spd -Def. I've given him the effect refined Wind's Brand, but I haven't given him anything else. I'm not really sure how to build him, but Wind's Brand seems to orient him more towards enemy phase. If anyone has suggestions for how to build him, or just good skills for him, please tell me below.

If you want to run him on enemy phase, res ploy would be a good idea. For seals, distant defense, SPD/ATK 3 or heavy blade, if you want to try taking advantage of the chill attack effect.
He's actually a really good player phase unit since he can take a hit and pull himself into vantage/desperation range afterwards, though I've yet to find a blue or green mage that can kill him on bait.
A lot of people seem to favor fury on him, but really, dartingblow, deathblow and swift sparrow are better as they give similar returns without compromising his ability to bait and kill, which is more how he's built. If you're only running him on single maps then it's probably fine; for TT, CC, and RD you'll want a blow skill, or at least replace his seal with brash assault if you're gonna keep fury.
I really want a close counter build for him combining close defense seal, def tactic and the owl boost but alas, Takumi's are scarce.
....I have maybe 7 builds for him currently, but right now I like his wind brand+eff with swift sparrow, desperation, speed smoke, and attack smoke (swapping between aether and moonbow as needed). Pairing him with VL!Ike for an attack + support + owl boost (plus spurs) is a nice bonus.
I'll probably swap attack smoke for res ploy when we get that seal though.
