Crying with bad H!Jakob

He's kinda like mine, +Res-Def. He has 35 base attack, so just give him Brave Bow.
Here's mine

Well, your choice really, even with bad Ivs, H!Jakob can still do pretty good, it's just he'll have less potential compared to other H!Jakobs.

This Iv is not bad. It's ~the same as neutral.

That isn't a terrible boon/bane. Admittedly it does reduce his ability to tank mages since RES is more important than HP for folks as slow as he is. However, if you make him a close counter murder stick he can still deal well with the physical foes he would face. And HP does help some there since it would make it easier for him to panic ploy them. But yeah, not a good boon/bane. But it isn't terrible or unusable by any means.

My cousin has that exact same set; she says he’s fine after she gave him Guard Bow. Just refine it for Res to make sure mages don’t doink him down as easily.
