Most thri-kreen only live to thirty years at most, but they are fully mature by the age of five or six and their reduced need for rest ensures they live the years they have to the fullest.

Thri-kreen have virtually no social structure other than the clutches they form with their families and closest allies. The notion of sophisticated rules for social behavior is foreign to them. They are almost always chaotic in alignment, and often neutral with respect to good and evil.

Different breeds of thri-kreen possess different builds, from little bigger than dwarves to taller than most men. However, none are as tall as trolls or ogres, or as short as halflings. Your size is Medium.

Your base walking speed is 35 feet.

When you aren't wearing armor, your AC equals 13 + your Dexterity modifier.

You have an additional set of smaller arms. You may interact with an additional object or feature of the environment for free during your turn. You can carry an additional weapon using both your arms, though weapons wielded in this way do not gain the benefits of the Versatile weapon quality, and weapons with the Heavy quality impose disadvantage on any attack rolls made with them when used in this way, as though you were a Small creature. However, if the weapon has the Light quality, you may use only one arm to wield it, and may carry two such weapons at once. You cannot use these extra arms to initiate grapples or wear shields. These hands can be used for other tasks, such as opening doors, carrying torches, using tools, or performing the somatic components of spells, without difficulty when they are not holding weapons.

You enter a torpid state instead of sleeping, during which you remain fully aware of their surroundings. You are fully rested after only four hours of torpor. You are immune to any magic that would put you to sleep.

Your long jump is 30 ft. and your high jump is 15 ft. You don't need a running start to make these jumps.

You have darkvision out to a range of 60 ft.

Thri-Kreen communicate with each other with a series of clicking noises. They can not normally communicate verbally with other races unless they work out a system or use magical means.

You are proficient in athletics, if another feature gives you proficiency in athletics you can add twice your proficiency bonus.
