I'm hoping for a guide that explains the whole process from the beginning step by step with explanations of what they are doing going through like making/adding the art and then scripting a spell to have the desired effect.
For example it might go like this for making a lightningball spell
1.) make file that looks like xyz.png (that they show you an image of) and this will look like a lightning version of the fireball spell.
2.) put xyz.png in NWN/DATA/spells/art folder
3.) make txt file called LBall.ssf (ssf meaning spell script filetype)
4.) first line is "LBall isAOE = true;"
5.) second line is "LBall AOEType = sphere;" (then they explain the other options like how to make it a line like a lightning dragon breath and how to choose the width and the length)
6.) after file is complete put it in NWN/DATA/spells/scripts folder
7.) after that spell is in game and works
Because frankly I can find a compendium kinda thing of all the variables or w/e but knowing how to use that to make a spell without guidance is impossible
Not sure if this stuff doesn't exist or never existed or if the games so old that all the guides either weren't online ones or the websites went offline since old games fan sites tend to die
