@JeremyECrawford I looked through with no luck on this, would a level 3 kenku warlock who heard someone cast a spell like blur (V only) be able to use him mimicry and cast it as well, provided he has a spell slot not used for the appropriate level?

A kenku's Mimicry trait doesn't confer the ability to learn new spells. #DnD https://t.co/IlnhHlFF5X
