Ultimate dreaming portent

You go to sleep with the willing to dream about the future of a creature. In your dream you can see what will happen to this creature in the next day.

For the next 24 hours, each time a dice is rolled concerning this creature, if you are aware of this dice, you can decide at will the result of the roll. You can decide for 3 dices, and only one dice can be affected per round. You have to decide before the roll.

When you decide for a roll, this roll cannot be modified by divination spells at lower levels.

A legendary resistance neutralize this effect, so the roll is made as normally it would be.

If you cast this spell before a long rest, you will lose your spell slot after finishing the long rest, and you can not perform any light activity within the 8 hours.
