race features:
Child of the Black Goat: You having a climbing speed equal to your walking speed.
Darkvision: Thanks to your eldritch heritage, you have surperior 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.
Eldritch Resistance: You have resistance to necrotic damage.
Legacy of a Thousand Young: You know the spare the dying cantrip. When you reach 3rd level, you can cast the false life spell as a 2nd-level spell once with this trait. When you reach 5th level, you can cast the mirror image spell once with this trait. You regain the ability to cast these spells with this trait when you finish a long rest. Constitution is your spellcasting ability for these spells.
Call of the Brood: If an Empty Moon is out while you are asleep, you have a dream (as per the spell, save DC 16). In this dream, the Black Goat places a compulsion within your mind, ordering you to carry out some activity as a torrent of images and sensations. When you awaken, you are automatically affected by a suggestion spell (save DC 16, cast as a 7th-level spell) in addition to the effects of dream, and must carry out the order.
Called "accursed" due to their monstrous appearance, they are feared by most, and their pwoers envied by nearly as many, letting their jealousy morph into hatred; an accursted existence indeed. These tieflings possess a fraction of the power of their dark mother's boundless reproduction and are incapable of creating life, though they can create figments of it, with the most powerful capable of creating ephemeral copies of themselves to fight in battle. These tieflings never stay in the city for long, vanishing shortly after reaching adulthood.
