I've adapted some races from the Earthdawn rpg, as it's one of my all time favorite settings. This is the lizard-like swashbuckling T'Skrang.
+2 Dex OR +2 Cha
Acrobatic Tail: The T’Skrang are swashbuckling bards and river rogues with a flair for the dramatic. Once per battle they can re-roll a flamboyant stunt check.
Swimmers: T’Skrang have partial gills which allow for long periods underwater.
Champion Feat: The re-rolled stunt check is at +2, if it’s a natural 16+ it does not expend the power.
