Your Constitution score increases by 2, and your Strength score increases by 1.

Young girtablilu grow quickly, able to walk as soon as they hatch, attain the size and development of a 10-year-old human child by the age of 3, and reach adulthood by 15. They can live to be around 800.

Girtablilu are tall and imposing creatures. They stand about 7-8ft tall with their scorpion bodies being about 5ft of this. But due to their heavy bodies, a girtablilu will generally stay low to the ground, being closer to 5-6ft tall. Their bodies are generally as long as they are tall. They generally weigh around 800ibs.

Your size is medium. 

Your base walking speed is 40 feet.

You can speak, read, and write Common and Terran.

Your great size and stature (along with being half scorpion) makes it easier for you to frighten others. You have advantage on intimidation checks.

You have two forward facing pincers that come out of your body in addition to your normal arms. These pincers are strong but limited in dexterity. These pincers can lift a number of pounds equal to five times your Strength score each. You can make an unarmed attack with the pincers that deal 1d6 bludgeoning damage. If you hit a creature with an unarmed strike from your pincers, you can use a bonus action to attempt to grapple the creature you hit. These pincers are unable to do anything that requires manual precision such as wield a weapon/shield or make motions for casting spells. If you have a higher damage die for unarmed strikes, you may use that die in place of the pincer’s normal die. 

Extending from your scorpion body is a long and deadly scorpion tail. You may make an unarmed strike with your tail that deals 1d6 piercing damage and that has a reach of 10ft. If this attack hits, the target makes a Constitution saving throw with a DC of 8 + your Constitution modifier + your proficiency bonus or be poisoned for 1 minute. The target can repeat the saving throw at the end of each of their turns, ending the effect on a success. You are able to poison a creature in this way a number of times equal to your proficiency bonus. You regain any and all expended uses on a long rest. If you have a higher damage die for unarmed strikes, you may use that die in place of the pincer’s normal die.

Girtablilu are no strangers to living underground, capable of carving out large networks of tunnels into the ground. You can create tunnels and chambers underground taking time based on the material you have to move.

Soft dirt and sand takes thirty minutes to create 10ft of tunnel just large enough to squeeze through and twice as long to comfortably walk through. Creating a chamber requires a full day and can be made no larger than twenty-five feet on either side and no higher than twenty feet

Harder dirt and clay takes twice as long

You cannot do this in rocky or flooded terrain
