Triton, Swampscale (5e Race Variant)
From D&D Wiki
Swampscale tritons are distant relatives of tritons who moved inward from the wide oceans. Seeing that corruption spanned more than just large bodies of water, sects of tritons set off to other parts of the world in search of evil to destroy. Indeed, they set their sights on creatures other than sahuagin and kraken. Swampscale triton, as per their name, are masters in the landlocked swamp areas of water. They are highly evasive and able to utilize the cover of the natural world in their battles against horrible beings like hags.
