race features:
Ability Score Increase. Your Strength score increases by 2, and your Wisdom score increases by 1.
Age. Thri-kreen live much shorter lives than their humanoids counterparts. A thri-kreen matures quickly, reaching adulthood within 3-4 years of hatching. Most thri-kreen only live to be 30 years old, although some live marginally longer.
Alignment. Thri-kreen, to many people's surprise, tend towards no particular alignment. Some are lawful if they come from a hive or a colony, following a rigorous social hierarchy set upon them since coming out the egg. Others tend to be chaotic, uncomfortable living by the societal standards the other races subject themselves to, often finding themselves acting in whatever fashion benefits them at the time. Regardless of this, it is rare that Thri-Kreen are good and evil.
Size. A full-grown thri-kreen stands six feet tall but can be as long as 6 to 8 feet, and can weigh between 100 to 375 pounds. Your size is Medium.
Speed. Your base walking speed is 30 feet and your hovering speed is 40. You sink in liquid and have a swimming speed of 0 feet.
Darkvision. Your compact eyes and deep instincts give you superior vision in dark and dim conditions. You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can't discern color in darkness, only shades of gray.
Exoskeleton. You have a natural external covering for support and protection. When you aren’t wearing armor, your AC is 12 + your Constitution modifier. You can use your natural armor to determine your AC if the armor you wear would leave you with a lower AC. A shield’s benefits apply as normal while you use your natural armor.
Extra Arms. You have four arms, your two regular arms and two smaller arms that are closer to the center of the chest. Your smaller arms have a reach of 5 feet, and you can use them to lift a number of pounds equal to five times your Strength score. You can use it to do the following simple tasks: lift, drop, hold, push, or pull an object or a creature; 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.
These smaller arms 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.
Thri-Kreen Weapon Training. The thri-kreen are known for their martial prowess with the chatkcha and gythka. You have proficiency with the dagger, spear, pike, and glaive.
Flight. You have a flying speed of 40 feet. To use this speed, you can’t be wearing medium or heavy armor.
Hive Link. With the assistance of your psionic abilities, you are able to work around your mandibles in order to communicate with others unlike your own. You have the ability to speak telepathically to any and all creatures within 60 feet of you regardless of shared languages. Because this ability can only be used by Thri-Kreen, you must still share a language with a creature to understand its replies.
Languages. You can speak, read, and write Common and Thri-Kreen.
