They set fire to the entire Apartment complex (not only Harry's apartment), because Harry's Wards were too good.
Good can be hard to nail down in this context.
Harry's wards are powerful, but they're also very direct and vulnerable to exploitation because of it.
In the very first explanation of what a ward is in the main Dresden Files books Harry mentions that wizards can do things like bind guardians to their wards. Creatures that get summoned when trigger conditions are met based on a contract/coercive binding, constructs, stuff like that.
This is presumably done to address this exact hole in the sort of wards Dresden uses; if someone tries something tricky you summon something with the reach to go out and stop them or otherwise take more flexible action.
The fact that Harry doesn't makes his hards narrow in an exploitable way that costs him dearly.
I agree his defenses should be on the bottom of the list, but they could still use some upgrades and that should be visible even with pure IC knowledge.
At very least when we talk to him about what we've been doing with warding we should make an argument to him about the necessity of adding summons to his defenses.
He's a proper wizard, we don't need to hold his hand for him to put something useful together.
You did not break it, the only thing that went in it were some herbs, some ash and water to make the mist. It will be fine with a good scrub. Also speaking os Salem era stuff, the part with the shears and the sieve is an authentic Salem era superstition, and in this universe an authentic means of ritual divination when working with unknown powers which Bob taught you as part of th general exchange of Occult lore
Did the cauldron get any neat properties from containing the essence of an exalt and a demigod and helping shape a brand new genus loci?
For that matter, is this the sort of thing the ordo could pick up insights from or was it too far beyond their reach to be useful?
When marcone hears about this we are really going to be reinforcing what gard said about us.
He isn't all knowing, Marcone probably won't learn about this until and unless it goes off and does something spectacular.
I'm hoping it hits that Skavos with the sort of Consequences that end up in legends. If anyone has "chew toy for least god made out curses forged from hellfire and death magic through the most infamous school of American Witchcraft" it's that guy.
