The Brute fighter archetype from Unearthed Arcana: Three Subclasses has the Brute Force feature, which adds a bonus die to damage dealt by weapons you are proficient in.
I want to know if abilities that work with weapon damage dice work with Brute Force's extra damage die, or not.
Below are some things that prompted this question:
Would abilities like the half-orc's Savage Attack trait and the barbarian's Brutal Critical feature let you pick the bonus die instead?
Would abilities like the Great Weapon Fighting fighting style* and the Savage Attacker feat let you re-roll the bonus die along with the original weapon dice?
