Forum:How long does it take for new items aqquired from monsters to appear as active weapons in your War Council.

I was just wondering how long does it normally take for new items to appear as items being used in your War Council? I defeated an Azriel earlier today and was awarded a purgatory shield which stats are 30/30, and the shields that are currently being used are Honors Defender, Sword of Redemption, Impenetrable Ice, Flamehide shield and 3 Deathshield. I would think the Impenetrable Ice would be replaced by the Purgatory. Can someone please shed some light on this?
