You have developed a natural talent for reading maps, delivery routes, journals and other recorded forms of scheduling and information, and use that to plan ahead. You can study multiple sources of information (minimum of 3) for 1 hour and prepare a plan related to its information. Once per day, while executing your plan, if you encounter an unforeseen complication, such as not having a code or key, lacking bait to distract a guard dog, or similar, you can propose a flashback. Your flashback is to a moment earlier in your planning where you secured some item or information that would help you overcome your current complication. You must have been able to have feasibly attained this item or information in the flashback to use this feat. Once your flashback has been proposed, the DM calls for a History check with the DC determined by the strength of your proposal. A totally feasible proposal is a DC 5, while a farfetched but possible proposal is a DC 13 to 15. Laughably impossible proposals are always a DC 20 or higher. On a success, your flashback succeeds. On a failure, your flashback may still succeed at the will of the DM, but suffers further complication, such as triggering an alarm, or potential harm.
