I've been trying to recall if there is an ability/spell/feat/whatever, that allows a player to go back and retake their turn (kinda like Prince of Persia style). I can't remember if it was something from 3.5 DnD or if there has been some sort of conversion from Pathfinder. If anyone knows of such an ability (or whatever it is), please let me know. I've been looking everywhere for it, and I simply can't find it.
Super Genius Games has the Time Thief, who does just that.
It is third-party material, but the Time Thief's Aevum power "Personal Time" does what you're looking for.
Thanks a lot. Do you know if there are any other abilities that have similar effects like this?
The closest I've seen is any number of the various "Roll twice and take the better result" and "Reroll before the results of the first roll are revealed" features (most in archetypes; I think the Unbreakable Fighter has one or two).
The ninth-level spell Wish (and possibly Miracle) can force reroll for one roll from the previous round, rewriting reality to accommodate the new results.
Personal Time is all I've seen that straight lets you take your turn, erase it, then take a completely different one.
In 3E psionics, there was a 9th level psionic power that did basically what you're looking for. I don't know if it was updated for PF by the 3rd party people.

Duration: Instantaneous

You can regress apparent time 1 round into the past. In effect, you “replay” the previous round of activity. The power regresses time to the point along the time stream just prior to your previous turn, undoing the effects of everyone else’s actions in the meantime. Once you have used time regression, only you retain knowledge of what happened during the round that is being replayed; however, you can communicate that knowledge verbally to your companions, if desired. During the round that you live through a second time, you can act on knowledge you previously gained by already living through the immediate future. In all likelihood, you’ll probably not choose to manifest time regression during your second pass through the time stream, instead taking completely new actions, but you pay the XP cost all the same.
XP Cost
1,000 XP.
Very very cool power, though costly to use and I can only imagine it's a pain in the ass for a DM to try and undo everything like that.
if you don't feel like being a psion, the Magic Item Compendium had a 1/day use activated version of said power, the Amulet of Second Chances (40,000 gp; page 70).
halflings luck lets you call a do over on a single roll...
And there's the Memory Lapse spell, which lets your opponent forget what just happened so you can try it again.
