@augustus27 Beating Gawain in a fist fight is always going to be difficult for Mordred, because he’s so far outside your weight class. If you’ve chosen the Warrior background then your main advantage over Gawain is your speed. That would give you a decisive advantage in a sword fight (at least in Chapter 1), but it doesn’t count for as much in a brawl.
If it were just the two of them then Mordred might be able to turn the tables on Gawain by attempting something underhand, but if you do that while you’re surrounded by his friends then you’re going to get dog-piled.
From a story-telling standpoint, I’d also prefer to give the player something to work towards if they want to develop an antagonistic relationship with Gawain.
Thanks for your comment, though - that’s an especially helpful challenge because it’s made me think about the background to the scene. This might be the first time Mordred hasn’t been able to beat up his little brother - for example, if Gawain’s recently gone through a growth spurt. Hmm… might need to add something about that to the text.
