Casting Time 1 round
Components V, S
Range close (25 ft. + 5 ft./2 levels)
Target 1d4 creatures who are or were within range of your current location in previous 1d2 rounds
Saving Throw none; Spell Resistance yes
You disrupt the flow of time in the recent past, allowing you to choose 1d4 attack rolls, saving throws, skill checks, damage rolls, or caster level checks (in whatever combination you desire) that you observed up to 1d2 rounds ago and force those rolls or checks to be rolled again, taking the new result in place of the old.
The distortion in the time-stream prevents any other aspect of the past from being changed, even if actions by other creatures in the intervening time no longer seem to make sense.
