Mantis

Mimikri: You can rapidly change the colors, patterns, and texture of your exoskeleton up to 3 times until molting during a long rest. You can use this to increase your stealth by +4 (or if you are in nature +8). This effect lasts until you move to an environment where your camouflage doesn't make sense anymore, or until you molt during a long rest.
Regeneration: Mantis can regenerate their arms and legs when they are cut off or otherwise removed.
Lurk: When you use mimicry and your target comes close enough for a melee attack without noticing you you gain +4 on attack rolls and crit on a 19 or 20. If your critical hit is already improved, this can improve it further.
Apposition eyes: During daylight mantis can see their surroundings sharply and gain advantage on perception checks involving sight. They gain +3 to passive perception related to sight.
Hunters Instinct: You are proficient in survival.
