NCF – Extended list of Neutral creatures.

Hmm, that's an idea. It would definitely be cool, but in multiplayer, some players might get the chance to recruit seven types of powerful creatures (especially the Dark Elementals with teleportation without sacrificing and returning, and the Mind Elementals of level 6), while others won't. There aren't many of them available each week, maybe 2-4 depending on the type, and the price varies from 500 to 1700. And how did you implement the Hell Gate in RTF? They drop randomly there.
