Forgot to add that Void Barrier only blocks and deflects ranged spells (i.e : Mystic shot, Dark binding, Primordial burst...poor Veigar)

Melee applied spells like Xin's and Rengar might trigger different effects (a brief stun maybe?) AOE skills such as Amumu's kit or Karthus Defile arent affected by Void Barrier.
