(See the inquisitor page on the Worlds of Adventure site for information on how the inquisitor class is modified from the Pathfinder version.)
For every 30,000 XP an inquisitor spends on epic abilities, she can switch out one of her spells known (of any spell level, from 0th to 3rd) for another one of the same level.
Domain powers: In Obormot's Reign of Winter, inquisitors do not gain their second domain power at 6th level, even if the power is gained at 6th level in the Worlds of Adventure campaign rules.
