Hi everybody! One of my players want to create a halfling barbarian in Pathfinder 2e and he wants him to wield a greatsword. My question is (I'm quite a newbie as a GM to this edition of the game): can a character from a Small sized Ancestry wield "great weapons" such as Greatswords or Greataxes? Are there any penalties? I looked into the rulebook but I couldn't find any of them. Many thanks! Stay safe!
