School: Chronomancy (Transmutation)
(Intended for use with the Chronomancer subclass)
Range: 1 month into the past / level
When Create Paradox is cast, the caster may alter a minor event from their past, which may affect the present. Such an event could be exchanging one memorized spell for a more useful one, having brought a cask of ale instead of a cask of oil, or deciding that, instead of insulting the orcs' chieftain (who has been harboring a grudge, and now the characters need his help), the heroes insulted their finest warrior. The event to be changed should not be more than 3 hours long in duration, and it must be something that was personally done by the caster, or something the caster could have directly influenced. (Perhaps the party's Rogue actually made the insult, and the caster uses Create Paradox to explain it away at the expense of the orc warrior.) Something should always be given up in trade for whatever is gained when this spell is used. The caster can change an event as far back as 1 month per caster level into the past. It is the DM's call as to how that change propagates forward, if at all. Often, things will not work out as neatly as the caster might hope. The orc chieftain could still bear a grudge (that the warrior was insulted), or the warrior might wish now for personal satisfaction.
Turbulence created by casting Create Paradox has a 5% per month affected chance of attracting a Time Demielemental or Chronomancer guardian from the demiplane of time.
Based on the 2e AD&D spell Paradox, from the Chronomancer suppliment (TSR 9506).
