I got one of those adventure pot 12m xp items from the event dungeon and noticed it had a 12m cooldown which was the exact same as my rez charm. When I later opened that box I noticed that my rez charm all of a sudden had a 16-hr cooldown. Does the adventure pot have a built in cooldown (I haven't gotten a 2nd one on this toon) and could it be accidentally shared with the rez charms?
