After years of living in close quarters it was inevitable that societal boundaries would blur. One product of this is the union of humans and dwarfs. What was once a rarity in the old kingdoms has become commonplace.
Your half-dwarf character has a number of inborn abilities, a combination of your human and dwarven heritage.
Ability Score Increase. Your Constitution score increases by 2, two other ability scores of your choice increases by 1 each. (Alternatively, you can increase your Constitution score by 2 and select one Feat).
Age. Half-dwarfs age at the same rate as humans reaching maturity at about 20 years old. However they also benefit from dwarven longevity, living as long as 200 years.
Alignment. Half-dwarfs have the capricious nature of humans, but tend to lean away from Chaotic alignments thanks to their dwarven influence.
Size. Half-dwarfs stand about 5 feet tall and average 200 pounds. Your size is Medium.
Speed. Your base walking speed is 30 feet. Your speed is not reduced by wearing heavy armour.
Darkvision. 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 colour in darkness, only shades of grey.
Dwarven Resilience. You have advantage on saving throws against poison, and you have resistance to poison damage.
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.
