Lizardfolk, Kamelos (5e Race Variant)
From D&D Wiki
Lizardfolk of the Kamelos clan were fervent worshiper of evil dragons to the point of color fanaticism. They ritually enchanted their scales to be able to take on a variety of colors at will to please the chromatic dragons. They were known to be colorful folk that used this skill to sneak around enemy defenses, like a chameleon. Other than the difference of scales, one could distinguish the kamelos by their gluttonous appetites, which resulted in slight potbellies for many of their members. This diet, however, has allowed for them to gorge and subsequently fast for long periods of time, perfect for military stakeouts when supplies were projected to be low.
This race variant replaces the cunning artisan and hungry jaws traits.
This race variant's new traits are chameleon and gorge.
