If he doesn't then here's how I see the battle going. I'll go over Khrones abilities
First it's important to know, Raven has fought a "Chaos God" per say before (Spider embodies the chaos that makes up the wizard101 multiverse), so the way she acts in this battle will pretty much be the same as when she fought Spider. She's pretty perspective, and could tell everything The Player and practically any one in the verse, even those comparable to her wanted to do even before conflcits between her and them happened, so she'll probably be in the same mindset she was during the fight with Spider and the destruction of the First world
Ap difference?: Not sure. Raven should be a few countless above countless, considering everytime The Player came back to the dunes, the narrator said the sands of times were even more "endless" than before.
Khorne existing outside the general laws of physics is irrelevant- The sprial itself doesn't work on the laws of physics and in relation to
general laws of physics, they can be consdered without law; don't follow general laws of physics as well. The Law manipulation and laws of physics these characters function by is the
laws of magic. She can manipulate general laws of physics, but that's not her go to. She can practically set the laws of magic to her favor and reshape laws across existence to her will. If she wanted, she could force Khrone to follow laws that she sets
His nonexistent stuff is pretty meh- Even The Player could slap a void of non-existence, even wall characters probably can tbh in the verse- It's what you have to do to advance in shadow magic.
Power Null of more abstract magic- Spider could do this too, Raven lolnoped it, and reversed it back at him. In fact, it made him a
High 4-C being, one even Adult
Morganthe could defeat. Note: Her power nullification isn't from Magic, it's from her own being.
Resistance to Magic- Everyone from Malistare the undying onwards is
"Immune" to magic in the game, but The Player still slapped him, and this is before he even got shadow magic, which has a specific sentiant being The Player can shapeshift into, who's core purpose is to cut through resistances and even immunaties. Immunaity and heavy resistance in the game is meaningless, that millions of people stopped playing the game because of it, because resistance and defensive strategy has pretty much dead. + Shadow Magic can bypass resistances to magic. That's it's core purpose.
They both have power type 2 concept manipulation, and they are both abstract beings, I'm not sure how many concepts Khrone embodies, but Raven embodies two across the wiz multiverse.
Also to mention, Grandfather Spider's purpose of existing was to act as someone she could never defeat. He was the perfect counterbalance to her, with his
Chaos and Shadow being able to match and cancel out her light and order. He was supposed to be
immune to everything she could do and more, yet she found a way to slap him and still sealed him away.
The issue however is that Raven was hesistant to stop Spider. But that was because she loved him so much and grew attached to him. That love doesn't exist for Khorne. I'm pretty sure if she wanted to, she could kill him, or more likely she would seal him away. To me this seems like Spider vs Raven all over again, but in place of Spider, it's khorne
I'll give it to Raven. She does the same thing she did to Spider
