This needs to be seen immediately, so I am posting it on the high-traffic section of the forum in hopes a moderator sees it and reports it to the devs.
Glowing Idol of Rebirth, if kept in a backpack, will still resurrect your character in battle to full health upon death, however, IT STAYS AS "GLOWING" in the backpack and ALSO creates a DUPLICATE ASHEN Idol that gets transferred to your inventory. This can be done perpetually, and the duplicate(s) can also be re-charged and added to another character's backpack, effectively making your entire party immortal for the entire game and unable to die. They'll just continue to get resurrected to full health and more duplicate Ashen Idols will be created.
Game-breaking to the MAX.
