Have some unofficial-but-developer-endorsed Overdrive Charms! Comes in both Lunar and Sidereal flavour, courtesy of Reminiscent Oasis and Revlid, respectively.

Note, these are not written with knowledge of 2.5, but it is assumed that any changes required in light of that will be minor. These Charms are unofficial, not canon and is produced to allow Lunars and Sidereals the important Overdrive mechanic when testing 2.5, since the writers were running short on time.
