@JeremyECrawford If I am a Warlock and I use an invocation to cast a spell that's not on the Warlock list (such as Levitate, Confusion, or Slow) requiring a save, does it use my Warlock spell save DC? Also, can such a spell benefit from Rod of the Pact Keeper?

The spells you cast through the Eldritch Invocations feature are meant to be warlock spells for you. #DnD https://t.co/ysQUzKLpEe
