* [[spoiler: Shiro]]'s death by torture.
** When they find him in the chapel. The walls are ''literally painted with his blood'' for the ritual of plague curse.
* [[spoiler: Harry's been tricked by Nicodemus into touching one of the cursed coins, meaning he's now got a copy of a Fallen angel in his head. He's not about to let it start him tempting him, but just as he's about to bury the coin in the floor of his lab, a voice whispers in his head. It only says ''Harry'', but it is nonetheless ''extremely'' creepy.]]
* Barabba's curse. You can sentence one person to death, and that will be it [[spoiler: although the Knights can take the victim's place, if they chose to.]] And it's in the hand of one of the vilest persons in the Dresdenverse.
** Its a continuous entropy curse which makes any area around the cursed individual unprotected by magic into a minefield. Trees fall into your path, power lines break off to hit you... and it could be perfectly explained away a a tragic accident. ParanoiaFuel to the extreme
* The plague curse. It infects the victim with almost any known illness, making "the Black Death look like chicken pox". And it spreads through air. [[spoiler: And it's released into a very busy international airport.]]
* [[GoodShepherd Father Forthill]] running down why Nidodemus is TheDreaded.
-->'''Father Forthill:''' Our information about him is limited. [[ShroudedInMyth He has made it a point to find and destroy our archives every other century or so, so we cannot be sure who he is or how long he has been alive.]] [[ReallySevenHundredYearsOld He may even have walked the earth when the Savior was crucified]] [...] [[ImplacableMan He's killed them. He's killed all of them. More than a hundred Knights. More than a thousand priests, nuns, monks.]] Three thousand men, women, children. And those are only the ones listed in the pages recovered from the destroyed archives. Only two Knights have ever faced him and survived.
* Cassius' snake curse. The person hit with it surrounded by a cloud which releases self-duplicating miniscule snakes which bites pieces out of the victim. And no, they don't have venom. The victim is EatenAlive, ''one piece at a time''.
* Mordite. A substance from outside the known universe and reality. ''Any living being'' touches it, dies. [[spoiler: It comes from the same place Outsiders come from]].
