The gray dwarves, or duergar, live deep in the Underdark. After delving deeper than any other dwarves, they were enslaved by mind flayers for eons. Although they eventually won their freedom, these grim, ashen-skinned dwarves now take slaves of their own and are as tyrannical as their former masters.
Physically similar to other dwarves in some ways, duergar are wiry and lean, with black eyes and bald heads, with the males growing long, unkempt, gray beards.
Duergar value toil above all else. Showing emotions other than grim determination or wrath is frowned on in their culture, but they can sometimes seem joyful when at work. They have the typical dwarven appreciation for order, tradition, and impeccable craftsmanship, but their goods are purely utilitarian, disdaining aesthetic or artistic value.

- Duergar Magic. When you reach 3rd level, you can cast the Enlarge/Reduce spell on yourself once with this trait, using only the spell's enlarge option. When you reach 5th level, you can cast the Invisibility spell on yourself once with this trait. You don't need material components for either spell, and you can't cast them while you're in direct sunlight, although sunlight has no effect on them once cast. You regain the ability to cast these spells with this trait when you finish a long rest. Intelligence is your spellcasting ability for these spells.
- Sunlight Sensitivity. You have disadvantage on Attack rolls and Wisdom (Perception) checks that rely on sight when you, the target of your attack, or whatever you are trying to perceive is in direct.
- Languages. You can speak, read, and write Common and Dwarvish. Dwarvish is full of hard consonants and guttural sounds, and those characteristics spill over into whatever other language a dwarf might speak.
