Stoneborn
Your eyes are adapted to the dark, otherworldly caves in which stone giants dwell. 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.
They can detect creatures by scent at a range of 30 feet, which expands to 60 feet if the wind is blowing towards them. You gain advantage on Perception checks that require olfactory senses.
