Halflings are not going to have the same vuln, and from a
physical standpoint they tend to be more like dwarves. They are stout, tough to poison, and not terribly adept in the water.

They are not as smart as gnomes, though they would be as or nearly as deft. Think closer to that of a really sharp human warrior. They would have no natural affinity for magic, no spellcasting. They would have a firm bonus to their charm saves.

and they could not wear shoes... and maybe vuln fire cause they got all that extra hair...

maybe be some of the priest classes, bard, thief, warrior, ranger...
and they act differently.

And hey, you even got the hometown already!

I love hobbits
