I have Meteorite Fragment Stud (earring - http://lucy.allakhazam.com/item.html?id=148115 ). It has soothing breath XV ( increase hp / mana 90/90 - http://lucy.allakhazam.com/spell.html?id=39814 ). I also have Advisor's Citrine Band ( ring - http://lucy.allakhazam.com/item.html?id=98964 ) which has KOTP XVII (increase hp / mana 83/87 - http://lucy.allakhazam.com/spell.html?id=38874 ) . these two effects will overwrite each other as expected. I use the 90/90 of course as it is better, but the lesser one will still overwrite the stronger if clicked. Now the problem : I picked up Enduring Grit Ring ( http://lucy.allakhazam.com/item.html?id=148436 ) which has KOTP XIX (increase hp / mana 93 / 97 ) and I would like to use it, but it will not overwrite either of my other two items. When I click it, I get a short duration (12 -17 second) buff ( not in the songs window either) that is called KOTP XIX. That is all that happens. I dug in my bank and picked up a Circlet of Life ( http://lucy.allakhazam.com/item.html?id=147285) which has KOTP XVIII and it works as expected. So check into the Enduring Grit Ring and KOTP XIX please.
