Kissassist INI Files
This page is the index page for Kissassist INI files that cover every class in the game. Starting at level 1 and increasing in 5 level increments these INI files upgrade spells & use any new Disciplines or AAs that become available. Not all of them are perfect (especially the melee ones, I don't know melee classes very well) but every one of them do work.
In addition to finding an INI file on each page, you'll find a list of links that'll take you to guides which teach players more about the inner workings of Everquest. What Heroic Stats do, what type of gear to focus on/get first, ways to improve your character with ways other than gear or leveling up and things of that nature.
