Some effects let you reroll the d20 or another die. When you do so, you roll the die again and use the new result if it is higher.

If multiple effects let you reroll dice, they don't stack. Once a die has been cast, you can reroll it no more than once.

For a d20 roll with advantage or disadvantage, you choose only one of the d20s to reroll. You can't reroll both dice.
