Mordenkainen Presents: Monsters of the Multiverse

Duergar are dwarves whose ancestors were transformed by centuries living in the deepest places of the Underdark. That chthonic realm is saturated with strange magical energy, and over generations, early duergar absorbed traces of it. They were further altered when mind flayers and other Aberrations invaded and performed horrific experiments on them. Fueled by Underdark magic, those experiments left early duergar with psionic powers, which have been passed down to their descendants. In time, they liberated themselves from their aberrant tyrants and forged a new life for themselves in the Underdark and beyond.

Like other dwarves, duergar typically have a life span of 350 years.

Sword Coast Adventurer's Guide

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.

• Ability Score Increase. Your Constitution score increases by 2, and your Strength score increases by 1.

• Age. Dwarves mature at the same rate as humans, but they're considered young until they reach the age of 50. On average, they live about 350 years.

• Size. Dwarves stand between 4 and 5 feet tall and average about 150 pounds. Your size is Medium.

• Speed. Your base walking speed is 25 feet. Your speed is not reduced by wearing heavy armor.

• Superior Darkvision. You can see in dim light within 120 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 gray.

• Dwarven Resilience. You have advantage on saving throws against poison, and you have resistance against poison damage.

• Duergar Resilience. You have advantage on saving throws against illusions and against being charmed or paralyzed.

• Dwarven Combat Training. You have proficiency with the battleaxe, handaxe, light hammer, and warhammer.

• Tool Proficiency. You gain proficiency with the artisan's tools of your choice: smith's tools, brewer's supplies, or mason's tools.

• Stonecunning. Whenever you make an Intelligence (History) check related to the origin of stonework, you are considered proficient in the History skill and add double your proficiency bonus to the check, instead of your normal proficiency bonus.

• 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 sunlight.

• 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.
