While a halfling reaches adulthood at the age of 20 and generally lives into the middle of his or her second century and a dwarf is considered young until they reach the age of 50 and generally live about 350 years; a Dwobbit tends to age and live to the average of both. This means they reach adult hood at about 35 and live about 300 years

Dwobbits can be as tall as 4 feet and weigh up to 100 pounds depending on which parent they take after. Your size is Small.

Your base walking speed is 25 feet.

Thanks to your halfling parent, you can move through the space of any creature that is of a size larger than yours.

You can speak, read, and write Common and Halfling. The Halfling language isn’t secret, but halflings are loath to share it with others. They write very little, so they don’t have a rich body of literature. Their oral tradition, however, is very strong. Meanwhile, Dwarvish is full of hard consonants and guttural sounds, and those characteristics can spill over into whatever other language you might speak.

Thanks to your dwarven parent, you have advantage on saving throws against poison, and you have resistance against poison damage (explained in the “Combat” section).
