Also, I don't play demons. I try to build Efreeti in the town, and then belatedly on the second week I can convert the meat into demons. Cavaliers rule in Castle, Vivi's [might weapons?] rule in Castle, so why is Inferno any worse? Efreeti in the town are also great; the other issue is that they can be harder to build due to poor respawn.
Well, it's an option; it all depends on the situation, of course. But Fire with Curse has its place :)
Скажу я вам, мои друзья.
Я некромант, я маг великий, и армия моя
Непобедимая, огромная!
