The Oni-Blooded are a race descended from the powerful oni, infamous creatures of darkness and chaos. They possess a mix of humanoid and oni traits, giving them unique abilities.
Darkvision: Thanks to your oni heritage, 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 gray.
Oni Resistance: You have resistance to cold damage.
Monstrous Physique: You have proficiency in the Intimidation skill.
Menacing Presence: You have advantage on Charisma (Intimidation) checks.
Oni's Might: When you score a critical hit with a melee weapon attack, you can roll one of the weapon's damage dice one additional time and add it to the extra damage of the critical hit.
Shadow Step: As a bonus action, you can magically teleport up to 30 feet to an unoccupied space you can see that is in dim light or darkness. You can use this feature once per short rest.
