The snow fairy was blocking me, Emeroll seduced a naiad. A mentalist was protected by a guardian. The resurrected one killed the Master – a fairy. It seems the rest of the killers ended up in natural defenses, as I don't see any other blocks besides the fairy. Gargantua was probably going for a kill, that's why he wasn't blocking. Or maybe he and the naiad found each other.
Here are three more skirmishes: against the Mafia, against an elf, and I'm not sure about the third one, I'll think about it later.
