Magic Circle

You can cast any spell with a casting time of an Action or a Bonus Action using a Magic Circle

When you cast using a Magic Circle, the casting time becomes 1 round. If you are moved, incapacitated, or disarmed of your writing utensil before the start of your next turn, the spell fails.

At the start of your next turn, the spell is cast using a spell slot 1 level lower than the normal spell slot cost. For example, you could cast Fireball as a 3rd level spell using a 2nd level slot.

You cannot us Magic Circles to cast 1st level spells without expending spell slots. Instead, the spell gains the benefits of expending a 2nd level slot despite you expending a 1st level slot. For example, Magic Circle Chromatic Orb deals 4d8 damage instead of 3d8 damage, and Magic Circle Command can affect two creatures instead of one.
