Lizardfolk, Rethild (5e Race Variant)
From D&D Wiki
In the Great Swamp of Rethild lived a particular type of lizardfolk. They were well-versed in stealth hunting, and preferred their natural weapons when they could. Their ravenous diet lent them great strength, which did not go unrecognized. This resulted in hordes of them being captured and enslaved by settlers in the Lapal region. Their servitude did not last and many of them eventually escaped into the surrounding areas, resulting in a diaspora.
This race variant replaces the Ability Score Increase, Cunning Artisan, and Hunter's Lore traits.
