Gold: A Day in Hell is the nineteenth Secret Mission in DmC: Devil May Cry. In this, Dante defeat a Ravager and 6 Stygians without getting hit by any of the enemies' attack.
It is recommended to kill the Ravager first. Dante can use Overdrive (charge 
/
, release then follow up with / ) to interrupt the Ravagers charging attack. Dispatching the Stygians would be easy enough once the Ravager is killed.
