The Drunken Lizard Pub

There was a thread about Avernum in the Games forum on SomethingAwful, and one of the posters there mentioned Eschalon.

What about stats? I started a game recently, and found that I lacked the Wisdom to learn the basic healing spell. Is there a minimum stat requirement for each spell, or each difficulty of spell, or just to learn any spell? And what are these minimum stat requirements? EDIT: Or maybe it was Intellige...
