IDK if you’ve gotten this question before, but for the Brute fighter archetype, if a half-orc fighter were to score a crit would you also roll the Brute Force die an additional time?Yes

@JeremyECrawford UA Brute, does Brute Force work with unarmed or no? it doesn't say "melee weapon attack" or "attack with a melee weapon" so it seems just a tad vague.

If a game feature says it works with a melee weapon, it means an actual melee weapon. As of the Player's Handbook errata, the rules don't consider your body to be a melee weapon. #DnD https://t.co/4AkGFkk4Qj

Unearthed Arcana articles are NOT open game content, yes? So i cannot use a Shifter in a non DM guild publication, yes?correct

Remember, Unearthed Arcana is a concept test. Nothing in it is officially in the game unless it appears in a D&D book. #DnD

If you have thoughts on an Unearthed Arcana installment, remember to fill out its survey—the best way to get your feedback heard. #DnD

If we decide to move forward with something in Unearthed Arcana, it goes through development and playtesting before landing in a book. #DnD
