Changes

Those who cease being chaotic and evil while being ravaged by Abaddon are in for a grim fate indeed - Abaddon doesn't tolerate treachery well. However, before their inevitable and utter destruction, they lose access to any spells, spell-like abilities and supernatural abilities from this class, and cannot continue to advance in it. They may [[SRD:Atonement|atone]] if they want to continue advancing and get their powers back (although it's questionable whether Abaddon would want them back at that point).
