|Why would you desperately want to create an offensive build for a unit that can't deal damage to save his life? In the wake of Generation 3, Jakob's BST and balanced stat spread has not been meaning anything for a long while in the realm of offensive Fire Emblem. Dagger units, however, reign supreme in debuffing, so let's make Jakob's build debuff-focused. He can absolutely afford to do that since trying to salvage his offensive capabilities is usually a fruitless effort, so he's not really sacrificing anything in the first place. This build relies on him getting a fully supportive role, so he literally only needs Speed to function. After his attack, Jakob's allies can begin to clean through the debuffed opponents or reposition him out of the way in the case of a more enemy phase-oriented team.
The trick of this build relies on most daggers having essentially both Def Smoke 3 and Res Smoke 3 built in them with the nifty advantage of affecting the targeted unit too. Adding Atk Smoke 3 in the C slot and Spd Smoke 3 in the Sacred seal essentially causes a mass debuff in all of the nearby foes' stats bar the one initiated on, with a whopping 28 ticks of debuff in total. One would say this is a poor man's Peshkatz, but if the ally team is already enjoying field buffs in the first place, the effect can be devastating.
Watersweep ensures that magical and staff allies cannot counterattack, removing a sizable part of what can counter him on initiation in the first place. Alternately you can go for Windsweep to instead screw daggers, archers and DC physical melee's counterattacks, but it's not as commonly available.
Barb Shuriken is here to help his special be ready quicker so he can actually damage stuff every second attack. In order to ensure Watersweep's activation, Darting Blow makes its way in the A slot, the dagger is Speed-refined and his IVs favor Speed to make him reach a respectable 42 Speed on initiation. Reposition is Reposition.
This set dies to being initiated on, by the way. But hey, even so, at least you're using someone who knows how to rock the fabulous butler style - even if that means little in battle.
Oh uh if you're feeling seasonal you can also give him a Kagami Mochi it does literally the same thing. IS why
