Prodigy Game Wiki

The Warden Keystones are key items that belong to the Academy with the only physical differences being its color and imbued element. During the tutorial, the Puppet Master uses Shadow Blast intending to destroy them, but he instead distributes them to different parts of the main island. Noot tells the player that the Warden Keystones cannot be destroyed, which is a secret that the staff of the Academy hid from the Order of Influence to thwart their plans. Each gem can be obtained by completing all tasks in its appropriate elemental location.

According to Prodigy Support, no more keystones will be added; the world of Prodigy was formed from five elements and no more. There is still an Astral symbol in the middle of the pedestals, but it only serves as a physical representation of the combination of the five keystone elements to create pure energy or power, as explained in Harmony Island Origins. Despite the presence of five keystones, there is a sixth Academy tower - the Astral Tower. If Prodigy Education develops all towers, all six should be accessible.

  • In 2018, due to players' Key Items sub inventories filling up with Warden Keystones and new quest items, Prodigy created a storage/collection area reserved for keystones, labeled as "Gems."
  • Prodigy Education prevented placement of the Firefly Gem until January 15, 2019, and the Shiverchill Gem until September 8, 2021.
  • Players will not see the pedestals post-tutorial until they receive the game invite to enter the Academy. During Starlight Festival, the crates are not present, but players are still restricted from the entrance through that path.
  • As of now, players not selected for beta testing can only place the Firefly Gem and the Shiverchill gem, as Gale is still "fixing the pedestals."
  • Noot requested players to go to the Ice Tower next when they cleared the Earth Tower and defeated Shadow Gerald, suggesting that a concrete order of keystone placement is mandatory.
  • Obtaining keystones out of elemental order does not affect gameplay in other locations.
  • The first versions of the Keystone sprites are still seen today as the icons for the worlds Grassy Plains, Coldshard, Cumulite, Emberland, and Riverdeep.
