Destroying the second camera | 4: Under Watch DMC: Devil May Cry Guide
Last update: 11 May 2016
But before you get to the new cameras, you'll have another fight in which you meet Frost Knights. The most important information is that you have to use angelic weapons against them, e. g. Osiris scythe. Of course, make various attacks to increase a multiplier. Avoid their attacks, because they may freeze you for a while.
After eliminating the first group of knights, other types of monsters join the battle. Follow your standard tactics against them. It shouldn't be difficult.
After a battle look around for interactive items, ignoring secrets on upper levels for now. At the very end choose a right passage which takes you to a new Divinity Statue.
Place yourself as the screen shows and use angelic Pull to get onto a platform over you. After that jump (you may use Angelic Boost) to a nearby Lost Soul.
Return the platform and jump onto next one. before you move on localize a blue grapevine (screen above) and use Osiris to go through (Prop attack).
BONUS MISSION: Search a small room shown on the 1st screen where you find Secret Door. If you have a Copper Key you can open it and begin a bonus mission Simple Traversal (2nd screen). It isn't too difficult, it's a time race. You can use only Ophion Angel Lift.
Return to where you've destroyed grapevines and place yourself as it's shown on the screen above. Use Angel Boost and fly to the shelf in front of you and then use a demonic Pull to destroy the second camera.
