Parallel Power

This feat adds a little extra power to your attacks when things line up in improbable ways. If you make an attack or cast a spell that requires you to roll more than one of the same type of dice for damage, any of those dice that roll the same number as another dice as part of that attack or spell can be rerolled once, with the new roll being added on top of the total damage from the original rolls. You can use this ability a number of times equal to your proficiency bonus before finishing a long rest.
