@TheVarsoscan Goliaths use a 2H weapon 1H given size large for carrying. Seems like it makes sense given weight would be the limitation? it's very tricky for balancing purposes – if you're OK with it in your campaign, it can work, but makes them powerful warriors

I would, as a DM, allow it with disadvantaged even with tavern brawler feat.
