You’ve learned to press every advantage you have, and some that you don’t.
                                  The following features:

• While attacking with advantage, if the sum of the rolls is less than 10 you may reroll both. This may only occur once per attack.

• While attacking with advantage, if the sum of the rolls is greater than 30, the attack becomes a critical hit if it was not already.

• When attacking with advantage, if both rolls are 20, double the damage of the critical hit after damage is rolled and modifiers added.

• Once per long rest, you can turn an attack with disadvantage into an attack with advantage. If the attack misses, you take 1d20 Psychic damage.
