In this video guide I will show you how to clear mission 11 without equipping a weapon set for Dante. Now to do this you must beat the game on Son of Sparda difficulty then you can buy Dante's last ability upgrade for being able to have more weapon slots or take off all weapons. Don't forget to put the difficulty to human as well. Once you take the weapons off you will only be able to kill enemies by using the royal guard stance and countering. Use your devil trigger gauge to fill up your devil sin trigger to be able to kill the enemies faster once you get the chance. Since using the regular devil trigger won't do any good without weapons. Same thing for the boss once the sin devil trigger is full using it once or twice will finish him off.
