AHAHAHAHA!
*lol* Sorry- just woke up and that struck me as funny.
The custom spells are actually part of the haks we *ahem* yoinked from the Isle of Styss. We don't have the scripting for those, so they don't work, naturally. So the spells-
Disrobe
Shock Weapon
Chill Weapon
Alter Self
(I can't remember any others atm) aren't going to work because we don't have the scripted support. Bug Neko when he gets home to relevel you so that way you can take the normal NWN spells and readjust your spellslots.
