Glass Guon Stone is a passive item and a Guon Stone.


  • Orbits the player, blocking enemy shots on contact.
  • Breaks if the player takes damage.


  • Synergy.png Max Pane - If the player also has Glass Cannon, if hit, the Glass Guon Stone will be destroyed, losing the synergy, but the gun will keep its ammo. Also changes appearance while active.
  • The player can have multiple Glass Guon Stones. There is no limit on the maximum number of Glass Guon Stones the player can have at once.
  • Using a Glass Shrine grants three Glass Guon Stones.
  • The Synergy.png Bullet Kiln synergy grants a Glass Guon Stone whenever Elder Blank is used, up to a maximum of 4.
    • This can be circumvented by dropping Glass Guon Stones until the player only has 3 and using Elder Blank, though this may require wasting a charge of Elder Blank outside of combat due to the difficulty in dropping items during combat.
  • Once unlocked, they are sold regularly next to the blanks in the shop and can drop upon completing a room.
  • As of the Advanced Gungeons & Draguns Update, Dropped Glass Guon Stones cannot be stolen by the Resourceful Rat.
  • Trading health to the Vampire for shells does not shatter Glass Guon Stones.
  • Can sometimes be found in Secret Rooms even before being unlocked.


  • The Glass Guon Stone, like all the other guon stones, is based on the Ioun Stones, popularized by Dungeons and Dragons.
  • The "Lady of Pane" in the item's description may be a reference to the "Lady of Pain" from the Planescape setting of Dungeons and Dragons.
