Ok bad word choice on my part Dark magic not nerco. Every single one of my points still stands with a simple word replacement.
Edit: I also didn't refresh, but we never see Dark Bob so much as raise a single zombie*. So I don't know where you are getting that. He did all sorts of dark magic.
*I think it has been a few years since I read the books.
This is not true.
We do not once see Evil Bob do magic that isnt necromancy or necromancy-adjacent. Necromancy is magic dealing with death; we see Evil Bob command evil spirits just fine.
In Ghost Story he constructs NeverNever fortifications around Mortimer's house, puts up Nazi flags, and has some sort of undead demonic spirits manning the defenses while wearing SS uniforms.
He himself wears an SS uniform.

I heard slow, heavy, confident footsteps. Clomp. Clomp. Then a pair of black jackboots appeared at the top of the trench. My gaze tracked up the SS officer's uniform, which included a black leather trench coat not too unlike my own. It wasn't one of the wolfwaffen. Instead of a deformed, monstrous wolf face, this being had only a bare skull sitting atop the uniform's high collar. Blue fire glowed in its eye sockets and it regarded me with cold disdain.
"A worthy effort for a novice," Evil Bob said. "I wish you to know that I regret your death as the loss of significant potential." He lifted what was probably not actually a Luger pistol and aimed it calmly at my head. "Good-bye, Dresden."
Evil Bob is not a joking moniker.
Described as a hack by Dresden just about every single time he came up.
Almost killed Dresden multiple times.
Turns out that Victor Sells could learn just fine.
So Cowl who doesn't have HellScry Charka misread Evil Bob's intentions and let him go. Seems like a skill issue to me.
Yes, Cowl, who stood at ground zero of a Darkhallow misfire and still walked away.
Cowl, who actually knew what Bob was well enough to send someone to steal him away from Dresden.
It seems that you just fundamentally don't seem to understand that we can read Bob far more comfortably than we can read Lash. You were the one that campaigned so strongly for HellScry Charka. Corpsetaker didn't understand Dark Bob or his intentions we can.
You are making expansive claims about a powerful evil spirit we have only met once, and that once we had no particular success at either putting him down physically or talking him around.
We broke his vessel and he fled. That was it.
This is not what Hellscry Chakra is for.
It will give you an edge on reading a person's emotions in a conversation.
Its not telepathy. Its not an absolute effect.
It wont tell you what the person is doing when you arent around or babysitting them.
