How Do I Add Magic Bonus to Weapon?
 

My Google-fu, Paizo-fu, and Lone Wolf-fu are all too weak, apparently. All I want is to add a +1 bonus to a weapon (specifically, a Bronze Dagger of Erastil). I can't figure it out, and can't wait to see what an idiot I am for not seeing something obvious.

I'd be happy to add +1 to a normal dagger for that matter. Please help.

Normal dagger is easy.

Add a magic weapon, first option on the list (before the specific weapons) is custom masterwork/magic item.

Click on that, assign the bonus and pick the weapon.

Thanks!
