Duels are a way of training your character. They involve defending your honour, fighting for sport, or for showing who’s the best, but ultimately, no one gets hurt – well, apart from your opponent’s pride. To start a duel, click on the character you wish to fight and select ‘Start a training duel’. Your opponent is free to refuse if they wish.
For a fight to the death, simply click on your opponent and select ‘Attack’. Be careful, though, for if you attack an honest citizen, there’s a chance you could lose Citizenship Points, depending on the laws in force at the time of the attack.
