Four-Colored Crystal Lamp

Four-Colored Crystal Lamp (四色のクリスタル) is the tentative name for this unknown type of monster located in the Lemegeton room inside the Great Tomb of Nazarick.

Appearance
This lamp-like monster was described to be comprised of four colors.

This lamp-like monster is seen hanging from above the ceiling of the Lemegeton room while lighting its surroundings.

Abilities and Powers
The moment an enemy entered their range, this crystal lamp would instantly summon high-ranking elementals of earth, water, wind, and fire. In addition to that, it is capable of bombarding their foes with area-of-effect attack magic. If these crystal lamps all attacked at once, the firepower they unleashed could easily defeat two parties of level 100 players, which are estimated to be roughly 12 people.

Trivia

 * In the Great Tomb of Nazarick, these lamp-like monsters happen to be located in the same room where the Golem of Lemegeton resides at.
 * In the game, two of these monsters were in the Lemegeton and were destroyed when the dungeon was transported to the New World.
