Chamelos

Unlike the Skinks and Saurus the Chamelos rarely live within their Seraphon temple cities. Preferring instead to be the nations scouts and spies. Navigating through the trees with swift movements and protecting intruders wishing to wage war against the Seraphon. Preferring to use poison laced blowguns to silently strike down their enemies without them ever knowing they are in a battle. Very rarely do Chamelos interact with non-Seraphons but there have been cases where they will join wood elves during battles should the two ever share a common goal.

When selecting a subrace, remove the following base lizardfolk features and replace them instead with the features listed for the associated subrace: Cunning Artisan, Ability Score Improvement, Hungry Jaws, Swim Speed, Hunter's Lore and Hold Breath.

Ability Score Improvement. Your Dexterity score increases by 2 and your Wisdom score increases by 1.

Adaptive Camouflage. As an action, you can change the color of your skin to match the color and texture of your surroundings, giving you advantage on Dexterity (Stealth) checks made to hide in those surroundings. You also have proficiency in stealth.

Prehensile Tail. You can grasp onto things with your tail. It has a reach of 5 feet, and it can lift yourself up if properly coiled around an object. You can use it to do the following simple tasks: lift, drop, hold, push, or pull an object or a creature weighing a number of pounds equal to five times your strength score, open or close a door or a container, grapple someone, or make an unarmed strike. Your DM might allow other simple tasks to be added to that list of options.

Your tail can't wield weapons or shields or do anything that requires manual precision, such as using tools or magic items or performing the somatic components of a spell.

Chameleon Vision. You have some of the best vision of any lizardfolk. You have proficiency in perception, if you already have proficiency in perception you have expertise in it. 

Zygodactyl Digits. You have a climbing speed equal to your walking speed.
