well, i'm making this build but replaced kukri for short sword as primary weapon and sling as secondary but i have some questions. I'm using kender subrace (halfling) and i noticed that the ab bonus from opportunist and the str damage/extra attack from cripppling strike are working properly with the sling and short sword but the +1 to threat range for weapons is only workin for the sling. It doesn't appear for short sword. both short sword and sling are small weapons. so do i have to use a tiny weapon with halfling for the cripple strike works properly? why sling works and short sword don't?
