Reaching Kat | 3: Bloodline DMC: Devil May Cry Guide
Last update: 11 May 2016
Just after your return the last battle begins with a new flying type of creatures, Pathos. They aren't dangerous, especially that you can pull them. As in the previous battles, watch out for chainsaw guys.
Before you leave this place, look around. Use an Angel Boost to get to a shelf (screen above) with a Lost Soul. You have to bounce from the higher point and land there.
BONUS MISSION: Next worth checking place is Secret Door shown on the 1st screen. Use Angel Boost to get there from the place where you've found a Blue Rose. If you have Argent Key you can begin a bonus mission to What Goes Around (2nd screen). It's not typical mission, because enemies in it can be damaged only by other enemies. Begin from attacking those on the ground, pulling them and waiting until flying ones throw explosives at you. Don't worry about health. Then finish off flying monsters. To eliminate the last one, you have to wait until he throws an explosive and then quickly pull him.
Kat is where she was, at the large abyss next to the arena. You need to use Angel Boost. I recommend to use double jumps. Reaching Kat ends this mission.
