I have a few questions about the "Miracle Circulator" (NX circulator). The description reads...
Double-click on the Miracle Circulator to reset your character's Inner Potentials, and possibly raise them a rank! Only works on Epic rank Potentials or higher, and cannot reduce the rank of any Potentials.
Has anyone verified that it really "cannot reduce the rank of any Potentials?" i.e. does the circulator really not lower the level of any individual line? Or do the circulators work similar to cubes (first line cannot be lowered, 2nd & 3rd line can be either equal level or 1 level down). I'd prefer an answer by someone who has actually tried them out in GMS, but information from KMS (or other versions) would be interesting as well.
In addition, I heard that the possible potential lines you can receive have changed as well. For example, someone informed me that you cannot get more than 25% buff duration on a single line, even if your lines are legendary. Is "attack speed + 1" still a possible line? If so, is it still legendary-only?
And lastly, does anyone have a rough estimate on what % chance the circulator has to raise rank?
Thanks for any help! :)
