Fast Casting

Requirements: Charisma, Intelligence, or Wisdom 20 or higher, the "Spellcasting" or "Warlock Spellcasting" features, Level 8.
Your skill with magic has grown to such an extent that you can perform the components for different spells at the same time. You may now ignore the normal rules for spellcasting limitations, meaning you may cast two spells of any level in the same turn, so long as one is an action, and the other is a bonus action, and neither have to be a cantrip.
You must have two free hands, or be carrying only your arcane focus in your hands in order to accomplish this.
