You can speak, read, and write Common and Primordial. Primordial is a guttural language, filled with harsh syllables and hard consonants.

You know the control flames cantrip. With this cantrip, you can also use it to affect magical fires. Additionally, if you provide adequate fuel and light it as a real fire, you can use Control Flames to increase the temperature of said fire to burn/melt objects with. Lastly, you can use Control Flames to make a wall of fire 5 ft. wide and 5 ft. long. This wall blocks any vision through it, and creatures that pass through or start their turn in it take 1d8 fire damage. This fire damage increases by an additional d8 at character level 5, 11, and 17.

Once you reach 3rd level, you can cast the feather fall spell once with this trait as a 1st-level spell, and you regain the ability to cast it this way when you finish a long rest.
