Just thought it'd be amusing if the skills dependent from necronomieconomics had names related to banking stuff, IE, the Pact of Fleeting Life could become Ponzius' Pyramid of Lifeforce, and such. The other skills would be similarily renamed. I know this wouldn't add anything per se, but would fit with the name, and has the potential of funny.
Yeah, one thing about necronomiconomics that bugged me a little is that it gets called the "Economy of the undead" but the only thing it really does with the undead is deal necromantic damage. It's mostly Cthuhlu-esque things, and in addition there's very little to do with economics in the name of the skills. The way they work actually has a little bit of economic stuff to it (i.e. refinancing your spells with something other than mana, which is cool)
