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.
