Ammuelia's Wish

Do not worry. I will never truly leave you.

Ammuelia's Wish is the most powerful gift to mortals from Ammuelia. By simply speaking aloud, you can alter the very foundations of reality in accord with your desires.

When you cast this spell, you duplicate any other spell of 9th level or lower (excluding a spell gifted by Ammuelia). This happens without needing to meet any requirements in that spell (including costly components), and the spell simply takes effect.

Alternatively, you can undo a single recent event within the last 12 hours. Reality reshapes itself to accommodate the new result. For example, your wish could undo an opponent's successful save, a friend's death, or entering an area. If undoing a die roll, you can force the reroll to be made with advantage or disadvantage. You can also choose whether to use the reroll or the original roll.

You might be able to achieve something beyond these boundaries, by stating your wish to the GM. Do this as precisely as possible, as the GM has ultimate power in deciding what occurs here. They may decide that, the greater the wish, the greater the chance that something goes wrong. For example, you may wish that a villain be defeated, and then you are shifted forward in time to a time where everyone is dead (effectively removing you from the campaign).

Every time you make a wish, there is a 5% chance that you can never do so again.
