Thri-kreen have insectile features and two pairs of arms. Their bodies are encased in protective chitin. They can alter the coloration of this carapace to blend in with their natural surroundings.
Although thri-kreen don’t sleep, they do require periods of inactivity to revitalize themselves. During these periods, they are fully aware of what’s happening around them.
Thri-kreen speak by clacking their mandibles and waving their antennae, indicating to other thri-kreen what they are thinking and feeling. Other creatures find this method of communication difficult to interpret and impossible to duplicate. To interact with other folk, thri-kreen rely on a form of telepathy.
Creating Your Character
When you create your D&D character, you decide whether your character is a member of the human race or one of the game’s fantastical races. If you create a character using a race option presented here, follow these additional rules during character creation.
Ability Score Increases
When determining your character’s ability scores, increase one of those scores by 2 and increase a different score by 1, or increase three different scores by 1. Follow this rule regardless of the method you use to determine the scores, such as rolling or point buy.
The “Quick Build” section for your character’s class offers suggestions on which scores to increase. You’re free to follow those suggestions or to ignore them. Whichever scores you decide to increase, none of the scores can be raised above 20.
Languages
Your character can speak, read, and write Common and one other language that you and your DM agree is appropriate for the character. The Player’s Handbook offers a list of widespread languages to choose from. The DM is free to add or remove languages from that list for a particular campaign.
Creature Type
Every creature in D&D, including every player character, has a special tag in the rules that identifies the type of creature they are. Most player characters are of the Humanoid type. A race option presented here tells you what your character’s creature type is.
Here’s a list of the game’s creature types in alphabetical order: Aberration, Beast, Celestial, Construct, Dragon, Elemental, Fey, Fiend, Giant, Humanoid, Monstrosity, Ooze, Plant, Undead. These types don’t have rules themselves, but some rules in the game affect creatures of certain types in different ways. For example, the text of the cure wounds spell specifies that the spell doesn’t work on a creature that has the Construct type. (The autognome is a noteworthy exception because of its Healing Machine trait.)
Life Span
The typical life span of a player character in the D&D multiverse is about a century, assuming the character doesn’t meet a violent end on an adventure. Members of some races, such as dwarves and elves, can live for centuries—a fact noted in the description of the race in question.
Height and Weight
Player characters, regardless of race, typically fall into the same ranges of height and weight that humans have in our world. If you’d like to determine your character’s height or weight randomly, consult the Random Height and Weight table in the Player’s Handbook, and choose the row in the table that best represents the build you imagine for your character.
Thri-kreen Traits
As a thri-kreen player character, you have the following traits.
Creature Type
You are a Monstrosity.
Size
You are Medium or Small. You choose the size when you select this race.
Speed
Your walking speed is 30 feet.
Chameleon Carapace
While you aren’t wearing armor, your carapace gives you a base Armor Class of 13 + your Dexterity modifier.
As an action, you can change the color of your carapace to match the color and texture of your surroundings, giving you advantage on Dexterity (Stealth) checks made to hide in those surroundings.
Darkvision
You can see in dim light within 60 feet of yourself as if it were bright light, and in darkness as if it were dim light. You discern colors in that darkness only as shades of gray.
Secondary Arms
You have two slightly smaller secondary arms below your primary pair of arms. The secondary arms can manipulate an object, open or close a door or container, pick up or set down a Tiny object, or wield a weapon that has the light property.
Sleepless
You do not require sleep and can remain conscious during a long rest, though you must still refrain from strenuous activity to gain the benefit of the rest.
Thri-kreen Telepathy
Without the assistance of magic, you can’t speak the non-thri-kreen languages you know. Instead you use telepathy to convey your thoughts. You have the magical ability to transmit your thoughts mentally to willing creatures within 120 feet of yourself. A contacted creature doesn’t need to share a language with you to understand your thoughts, but it must be able to understand at least one language. Your telepathic link to a creature is broken if you and the creature move more than 120 feet apart, if either of you is incapacitated, or if either of you mentally breaks the contact (no action required).
