^Talking to Eluned with a charged crystal teleport seed in your inventory adds a right-click option to teleport outside the Temple of Light or to Lletya. However, this dialogue only occurs when you find Eluned traveling in Isafdar, it will not show up if you talk to her in Prifddinas.
The crystal teleport seed has four teleport charges when initially received and, when used up, can be recharged in several ways. A crystal teleport seed can only be recharged if it is completely out of charges. Crystal teleport seeds obtained from Elf warriors are initially uncharged.
The elves, Eluned (Islwyn after The Light Within) or Ilfeen, can be paid to recharge crystal teleport seeds. This method of charging adds three charges to the seed. The cost of recharging with elves decreases after each recharge. The recharge count is by player, rather than by crystal. These elves can recharge more than one crystal at once. Partially charged crystals can not be recharged. While there are several places that players can meet Eluned or Ilfeen, the recharging service can be completed anywhere by using the spell NPC Contact and talking to Eluned / Islwyn.
Following Plague's End, players with level 85 Smithing may use the crystal singing bowl within the Ithell Clan district of Prifddinas to enchant their own seeds. This requires the player to have 150 harmonic dust and an uncharged seed in their inventory. Partially charged crystals cannot be recharged. This method grants the seed a total of 4 charges.
It is recommended to have Eluned or Ilfeen recharge teleport crystals, as the time required to gather 150 harmonic dust is not worth saving a mere 150 coins.
The former animation for a player using a crystal teleport seed
Before 15 September2010, the crystal teleport seed's inventory icon was small. This update enlarged the icon, making it easier to click. As of 6 October 2010, the crystal teleport seed's inventory icon was changed back to the original size.
After the release of the second batch of Prifddinas on 10 November2014, the inventory icon and teleport animation of a crystal teleport seed were updated. This was then slightly reverted on 24 November, and the teleport animation was changed back into a normal teleport.
Originally, the crystal seed was a one-click teleport to Lletya. With the addition of the Temple of Light destination, this functionality was removed. Some players purposefully did not collect the quest rewards in order to keep the one-click teleport. After player feedback, this ability was restored on 15 September 2010. Instead of a dialogue box, a right-click option allowed the teleport to the Temple of Light.
The crystal teleport seed will only work up to level 20 wilderness.
If you attempt to alchemise a crystal teleport seed, a message appears in the chatbox saying: "You can't do that to an elven crystal!"
