The cracked divination urn (full) is an item made by filling a cracked divination urn while harvesting or converting memories. It can be teleported to Ernie by clicking it, giving 210 Divination experience. Players can have up to ten full urns at any one time. Once that number is reached, new urns will not start collecting charges. A full urn can also be given to Ernie manually by using the item on him, or through a chat option while having a full urn in the inventory. Full urns can also be teleported automatically by toggling the "Auto-teleport current skilling urn when full" option on under skilling options in miscellaneous gameplay settings.
Player can also use urn enhancer unlocked at level 24 Invention to get 25% more experience.
