School: Chronomancy (Transmutation)
(Intended for use with the Chronomancer subclass)
Range: 2 rounds into the past / level
When this spell is cast, the caster may take back an action performed sometime within the last 2 rounds per caster level, or insert an additional action if timing permits. The caster could take back something said, or decide not to kiss the king's daughter. They could NOT insert another attack into a combat round (unless an attack was intentionally skipped during the target round), but COULD insert an attack into the round BEFORE combat.
If an action is taken back that would've prevented combat (insulting the goblin king) or another major event, the caster and DM will need to work out a reasonable course of events that would make up for that lost time.
Turbulence created by this spell has a 1% per round affected chance of attracting a Time Demielemental or Chronomancer guardian from the demiplane of time.
Based on the 2e AD&D spell Minor Paradox, from the Chronomancer suppliment (TSR 9506).
