In honor of Professor Snape’s birthday today, Pottermore added a new spell to the Dueling Club.
The Smokescreen Spell, or Fumos, is a defensive spell; the Insider predicts it was useful to Snape when necessary.
Previously, for Halloween, the site added four incantations for users to play in Dueling Club, including the Tickling Charm, the Levitation Charm, the Freezing Charm and the Disarming Charm. All spells are available on pottermore.com by clicking “Dueling Club” on the Map.
Regarding Severus Snape, in the most recent update on Pottermore, J.K. Rowling cleared up rumors that the Potions Master was a vampire — read it here.
Happy Birthday Professor Snape! You will always be in our heart.
