Hey guys, I've seen we have a lot of players both new and old returning who may be rusty on NWN mechanics. This is a source that many older players have used for a long time which you can easily search for information about classes, abilities, feats, and pretty much anything NWN related.
The one catch is that EFU has made a lot of changes, but it is a great source of information on the base mechanics of NWN if you are less familair.

Might save you having to ask IRC everytime you're curious about some mechanics and find out some stuff you didn't know. There's a lot of hidden quirks to NWN.
