I would try a rogue type archer/dagger build.
In the Wiki, if you click on Enderal, go down to Memory Trees and click, then you will see the Rogue tree, then click Trickster to see the various possible talents relating to archery, and Infiltrator has some talents for bows and daggers. You can also explore the other memory trees. The Warrior-Blade Dancer path has some 1H buffs, but I don't know how much they help daggers, but it is better to focus on gaining talents in just 1 or 2 memory paths, especially at the start. In the skills area, you can increase Archery to improve your bow damage, and 1H I presume to improve daggers (I can't say for sure as I don't use daggers myself).
In my playthroughs, I always focus on archery so if you have any specific questions feel free to ask.
