Thri-kreen

Thri-kreen have insectile features. Their bodies are encased in protective chitin. Some phenotypes possess two pairs of arms or wings. Some can alter the coloration of this carapace to blend in with their natural surroundings.

Although Thri-kreen doesn’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 others, thri-kreen rely on a form of telepathy.

The RAW of Spelljammer describes a very defined appearance for Thri-kreen. In my universe, their shape is a bit more varied and runs the entire gamut of humanoid bipedal insectoids.

If you wish to play such a different form, the stats for the specie can be adjusted accordingly.
