-Atk +Def Halloween Niles?

Hey this is my first post coz I saw no one has replied to your question yet so I finally went to create an account haha.

Grats on the Niles summon! H Jakob has been my go-to armour ranged, and I've been playing him a lot using the Brave Bow-Bold Fighter setup. With 31 base attack on your Niles, you probably shouldn't go with Brave tho. Maybe try Slaying Bow or Guard Bow with speed refine? Those two weapons would make use of his mixed defenses, and you can turn him into a ranged bait unit backed up by a few stacks of ward armour. If so, a Bond skill or Distance Defense might be useful here to increase his speed/defenses further without using L&D; or close counter (but Takumis are rare so maybe not). Distant defense seal for further defenses. He becomes deceptively tanky with his high speed that avoids doubles. I guess keeping his devil bow might work too if you're afraid of opponents charging up their specials.

You got a really cool unit, don't let IVs spoil the joy of that! He looks amazing. Hope this helped.
