Generic, Text: Deep Elf

Languages. In a deep elf society, you learn Common, Undercommon, and—more as deep elves have recently reconnected to their surface counterparts—Elvish.
 
Superior Darkvision. If you have darkvision from your ancestry, it has a radius of 120 feet. If you do not have darkvision from your ancestry, you have adapted to a life of underground darkness. 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 grey.
 
Twinkling Tricks. Deep elf culture almost universally reveres the goddess Lolth, including her magic. You know the dancing lights cantrip. When you reach 3rd level, you can cast the faerie fire spell once with this trait and regain the ability to do so when you finish a long rest. When you reach 5th level, you can cast the darkness spell once with this trait and regain the ability to do so when you finish a long rest. Charisma is your spellcasting ability for these spells.
