My half-orc rogues use slings to launch halflings. He doesn't get any bonuses and halflings aren't very aerodynamic but they hit harder.
I have a halfling slinger. Equiped with sling and bullets. Starting Featoint Blank Shot. When he hits my "to hit" explaination says, "Dex +5, Size +1, Point Blank Shot +1". I am playing the 5.6 Mod. Do I have a problem with my Mod or did I intall it wrong or is there a bug when you choose Point Blank Shot? (I'll make a test halfling without that feat when I get home and see). Any thoughts?
In vamilla, the feat seemed not to be working, I've never notices it was working in any af the Co8 mods. Otherwise, I'd use one as the basis of a "thrower" using Ted's flasks.
I had handled this issue about a year ago in a long dead thread. I had shown how the racial bonus can be applied to halflings through protos.tab for PCs. Based on what was shown in the above post, it appears that this has not been implemented.
