I’m looking for ways to take the most advantage of this new ability from the upcoming Tasha’s Cauldron of Everything:
You entreat your patron to grant you a small wish. As an action, you can speak your desire to your Genie’s Vessel, requesting the effect of one spell that is 6th level or lower and has a casting time of 1 action. The spell can be from any class’s spell list, and you don’t need to meet the requirements in that spell, including costly components; the spell simply takes effect as part of this action. Once you use this feature, you can’t use it again until you finish 1d4 long rests.
Most of the spells with material costs or permanent/"until dispelled" effects I’ve come across either have a cast time longer than 1 action, or are level 7 or higher. So far the only spells I’ve found are Revivify and Continual Flame. What else am I missing?
