diavolo's epitaph

 your character takes a brief look into the future. when a creature that you can see rolls for attack. you can use your reaction to skip time. the attack automatically misses, and if the creature is within 5 feet of you, you can make a weapon attack with advavtage on the creature. if you don't have the feature sneak attack you can add 1d6 to the weapon's damage. And if the creature isn't within 5 feet of you, the next ally thet attacks them in this round gets advantage on their attack roll. and until the end of your next turn your ac is increased by 2.

at higher levels. if you cast this spell using a spell slot of 3rd level or higher, add 1d6 to the weapon attack damage for each spell slot above 2nd level.
