Everchanging Lunacy

At the start of your first turn, choose between Moonlight Form and Moonshadow Form to use at that turn. You gain the form and toggle to the other form at the start of each of your turn.

Moonlight Form - Upon healing an ally creature that you can see, you can choose to shroud their existence with the power of the moonlight. This grants them one "duplicate" as if they are under the effect of Mirror Image, allowing attacks to potentially hit the duplicates instead. One duplicate grant light obscurement to the ally, two duplicates grant heavy obscurement to the ally, and three duplicates prevent hostile creatures from being able to see the ally unless through blindsight and tremorsense.

Upon healing an ally creature that you can see, you can choose to designate them as your mirror duplicate, as if you are under the effect of Mirror Image. This allows you to redirect attacks towards one of (up to) three allies, prioritizing the closest ally first. The dice redirect roll is treated the same way as Mirror Image, and this effect lasts until the start of your next turn.

Moonshadow Form - Upon damaging a hostile creature that you can see, you can apply the effects of Faerie Fire on the target until the start of your next turn. While affected this way, you can choose to ignore resistance to one damage type of your choice against that target.
