Timewarp does sound stupid good. Does it mean a character buffed with haste/flesh sac will be able to get two 6 AP turns in a row? Do statuses go down a turn on that second instant turn?
Selectable origin skills would be nice for custom origins, though the custom skills for the origins are mostly thematically relevant. Could be nice to have like 3 different source skills to choose from for a custom origin. Maybe something that can be modded in.
