Dune Dwarf

Darkvision. Accustomed to working by star-light, you have 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 grey.
Sun Forged. You have advantage on Constitution saving throws against exhaustion due to lack of food and water. You're also naturally adapted to hot climates, as described in chapter 5 of the Dungeon Master's Guide.
Dwarven Combat Training. You have proficiency with the glaive, dagger, light hammer, and scimitar.
Tool Proficiency. You gain proficiency with the artisan’s tools of your choice: leatherworker’s tools, cartographer’s supplies, or glassblower’s tools.
Dunewalker. Whenever you make a Wisdom (Survival) check related to navigating the desert environment, you are considered proficient in the Survival skill and add double your proficiency bonus to the check, instead of your normal proficiency bonus.
Dwarven Toughness. Your hit point maximum increases by 1, and it increases by 1 every time you gain a level.

Languages. You can speak, read, and write Common, and Dwarvish.
Extra Language. You know Sand Sign, the secret and subtle language of the Dune Dwarves that combine hand signals and coded words. Sand Sign can be used to communicate covertly while still seeming to have an innocuous conversation.
