Critical Control

You are a master of combat, able to seize the moment and turn a critical hit into a powerful advantage. When you score a critical hit on an attack roll, you can choose to forgo the extra critical damage and instead activate Critical Control as a reaction. The extra critical damage is not counted, and instead, you choose one of the following benefits based on the amount of extra damage the attack would have dealt:

• 1+ extra damage: You gain a +1 bonus to all attack rolls you make before the end of your next round.
• 6+ extra damage: You gain a +2 bonus to all attack rolls you make before the end of your next round.
• 11+ extra damage: You gain a +2 bonus to your AC until the end of your next round.
• 16+ extra damage: You gain a +3 bonus to your AC until the end of your next round.
• 21+ extra damage: You gain resistance to all elemental damage types until the end of your next round.
• 26+ extra damage: You gain immunity to one damage type of your choice until the end of your next round.
• 31+ extra damage: You gain advantage on all attack rolls, ability checks, and saving throws until the end of your next round, and you can take an extra bonus action on your turn.

Once you use Critical Control, you cannot use it again until you finish a long rest.
