If you die with your Accursed urn, you will lose the urn and its entire contents as it will not appear at your Gravestone. An accursed urn requires two batches of Soft Clay and an Air rune. When it is 25% full, the player will get an orange message saying "Your accursed urn is a quarter full." When you check how full your urn is and it's at 50%, the player will get a message in the chat box saying "This Accursed urn is half full, or is it half empty?"
