race features:
Bounder Guard
Stout halflings are hardier then the rest of their kin, more able to stand their ground rather then run for the road. As a result their communities train the young in traditional halfling weapons when using a weapon with halfling in the name you have profiency, if you already have profiency you have expertise.
Stout Resilience
It is rumoured that the Stout have dwarven blood running through them and this is what hardies them to poision and liquor. You have advantage in saves vs poison and drunkness.
Down by the River
Living in generally the inner reaches of Lurien or Duchies, Stout Halflings have a natural adversion to waters deeper then themselves and are unable to swim. If forced into the water a Stout must make a WIS save vs fear for every round they finish in water.
Stouts are the halflings that tend to form the large farming communities that most think of when asked about halflings, they have a strong love of simple pleasures such as music, drink and tobacco.
Blend in with the crowd
Not ones to normally rock the boat, or be in one, Stouts take great pains to fit into a community and become a helpful member. Due to this Stout communities tend to be quite close knit, and rather gossipy.
Stouts work readily with others, even non-Hin, and are loyal to their friends. When their companions or community is under threat they have been known to display a surprising level of ferocity.
