The character can copy moments in time, and replay them later. Fundamentally, anytime the character rolls a dice to perform any action (in or out of combat), he may expend an extra action to copy and store it for the future. The character can have one such action saved for each level he possesses. When he wants, the character can simply repeat a saved action, deleting it from his repertoire. When he does so, he performs the same action in the same way, getting the same results as saved on the dice roll.
(EG: Familiarity, a 3rd level experiment, lashes out at a ninja with a front kick, and rolls an 18 to strike (22 with her strike bonus). She copies that action realizing that good kicks are hard to find. One round later, because her ninja is still standing, she performs the exact same front kick. Instead of rolling, she just assumes a 22 strike roll.)
Theoretically, the character could simply practice certain preferred actions in a gym until he or she gains the desired strike roll. This is acceptable, and part of the design of the power BUT training and practice differs from real world experience so much that it's effects are limited. If the character spars or practices, just assume a held strike roll is an 18, or a skill use is a 15% on the dice roll. Likewise, if the character spent all morning copying jump kicks, he cannot use those stored actions for her sword strikes.
There are likely many out of combat uses for this power. Using it to 'memorize' looking at a license plate to be relived when talking to the cops is one such, or copying a moment where a limited resource was used is another.
