With the Night Hag Warlock Pact, Shadow Evocation the warlock gains access to Shadow Bolt. As this is not the direct spell it can be cast back-to-back. I am unsure if this is intended or not. If this is not an exploit I want to use it. If it is an exploit I want to avoid doing so and this can also act as a notice in case it was overlooked.

Thank you for your help.
