I'll share my current notes for the Wallara/Chameleon Men.
Ability Score Increase. Your Dexterity and Wisdom scores increase by 1.
Bonus Proficiency: You gain proficiency with History. Additionally, you may choose one of the following skills to gain a proficiency with: Animal Handling, Nature, Perception, and Survival.
Mimic: You can spend 1 minute adjusting your skin to match that of your surroundings.
Once you are camouflaged in this way, you gain a +5 bonus to Dexterity (Stealth) checks as long as you remain there without moving or taking actions. Once you move or take an action or a reaction, you must camouflage yourself again to gain this benefit.
Sense of Direction: You gain advantage on all Wisdom (Survival) tests you make for navigation.
Vanishing Step: As a bonus action, you can magically teleport up to 30 feet to an unoccupied space you can see. Once you use this trait, you can't do so again until you finish a short or long rest.
I'm currently debating increasing the bonus to Stealth checks to +10.
