Royal Seed Pod
The Royal Seed Pod is a 1-click teleportation item that can be bought from King Narnode Shareen for 1 Billion gp. The King is located in the center of the Grand Tree in the Tree Gnome Stronghold. To get to the Grand Tree, use the skilling teleport to the Gnome Agility Course and then run north. The Royal Seed Pod works up to level 30 wilderness similar to the Amulet of Glory.
The location of the teleport is just outside the Crash Site Cavern north of the Tree Gnome Stronghold. This item is very useful for killing Demonic Gorillas as it is the closest teleport to the entrance, making for faster trips.
The Royal Seed Pod has unlimited uses, but is lost on death. If it is not picked up, it will disappear.
