(After you defeat the first pair then 2 more Graces and 1 more Glory appear, this is on Hard/Infinite Climax) Once one dies it will drop its claws, these claws can do some serious damage so it's suggested to pick them up. Your best bet is to dodge the slashes and activate Witch Time. Their tactics vary but they'll usually be strafing you. Its attacks are also more agile, and it's usually sliding along with striking, giving it deceptively long reach. Glory tends to be much more mobile on the battlefield, sliding back and forth to dodge incoming attacks before striking. Tends to drag its claws along the surface of the ground before swinging. Grace is the power fighter of the two, its attacks are a bit slower, and it uses wider sweeps and Most of their attacks are quick and always on the move. These guys use several different kinds of techniques. Once the cutscene is over, you will immediately be attacked so be ready to dodge. They are very fast opponents and can be difficult. These two utilize fire (Grace) and lightning (Glory). As you head to the left a cutscene will start and introduce Grace & Glory.
Either way, you'll reach a small area (Umbran - Training Ground Ruins). You will eventually encounter a group of Decorations (Grace & Glory on Hard/Infinite Climax), you can either run by them or kill them. Follow the path, but be prepared, because parts of it will break and fall off, or simply crack and move. After it finishes, you will find some of Antonio's notes and, on Hard difficulty, there is a Crow directly behind you at the edge of the platform. You start the chapter off with a cutscene.
