Fast as Lightning

Your reflexes are exceptionally sharp and quick, granting you the following benefits:

• You can use two reactions between the start of your turn and the start of your next turn. However, these two reactions cannot be used to activate the same effect twice. For example, you cannot make two opportunity attacks within the same round, and a rogue with Uncanny Dodge cannot use it more than once within the same round.
• Whenever you fail a Dexterity saving throw, you can immediately use a reaction to reroll this saving throw. The result of the second roll replaces the first.
