A cracked hunter urn is the resulting urn after the player starts filling a cracked hunter urn (empty). While the player carries the urn in their backpack, it will fill up passively as the player hunts creatures requiring up to and including level 11 Hunter, until it is filled with 1,100 experience and becomes a cracked hunter urn (full).
The fully filled urn will grant 220 Hunter experience after teleporting the urn to Ernie. While carrying an urn enhancer, it will instead grant 275 experience per teleported urn for a cost of 20 charges.
Making the urns and adding a mud rune to the urns requires level 3 Crafting. The Assist System and temporary skill boost can be used to do so. Filling the urns and teleporting the urns does not require a Crafting level.
Only the base experience gained is considered; additional experience from sources such as the mad necklace, experience lamps, or Double XP do not count towards the urn's filling.
Bonus experience has no effect for both filling and teleporting the urn.
