Power crystals

Marshal's Refuge Cave in Un'Goro Crater.

Power crystals can be found throughout the Un'Goro Crater and Sholazar Basin, though except for particular quests, the ones in Sholazar Basin cannot be collected as of yet.

They cannot be sold to vendors but can be auctioned or traded. They stack in 100.

Un'Goro power crystal varieties

•  [Blue Power Crystal]

Power crystals can be used for various things

Historical uses

A human male wearing the Thorium armor set.

Prior to patch 3.1.0, the Thorium armor set required various power crystals in its construction and provided extra resistance to all magic types.

•  [Thorium Belt] (4  [Red Power Crystal])
•  [Thorium Leggings] (4  [Red Power Crystal])
•  [Thorium Armor] (4  [Yellow Power Crystal])
•  [Thorium Helm] (4  [Yellow Power Crystal])
•  [Thorium Boots] (4  [Green Power Crystal])
•  [Thorium Bracers] (4  [Blue Power Crystal])

Since patch 3.1.0, this set has lost its resistance and requires no crystals.

Prior to patch 4.0.3a, you could turn in 7 of each crystal to be studied by J.D. Collie in  [15-30] Crystals of Power.

Notes

• A major plot element in Land of the Lost are the pylons, devices of unknown origin which open portals through space, time, and dimensions. They are powered and controlled through consoles comprised of patterns of red, green, blue, and yellow crystals.
• It may be significant that there are no silithid hives near the pylons except in the south, where a southern pylon is mysteriously absent.

The Power Crystals of Un'Goro

This section contains information from the Warcraft RPG which is considered non-canon.

Excerpt from "The Power Crystals of Un'Goro" by J.D. Collie

Amid the rocks and rich soil of the crater floor can be found all manner of colorful crystals, each as fragile as glass. Held to a light, they seem to flicker and glow like flames... They seem to have no useful purpose, or so I believed at first, until I found the first Crystal Pylon. Located in the east, guarded by the pterrodax, this humming pillar holds the same sort of runes found on the Stone Guardians as well as the hovering pylons that guard the entrance to the crater. All my attempts to decipher this ancient tongue have met with failure. And yet — the pictographs clearly show power crystals being used for something. A ritual, a spell, I do not yet know...

Although the crystals come in all shapes and sizes, I have classified them in four main colors: red, blue, green and yellow. I've never found anything truly in between these shades, so there are no orange or brown ones, for example. Anyone who isn't color-blind can tell them apart by a glance. What's more, I’m fairly certain the crystals can be employed by the Crystal Pylons. If I could figure out the right pattern — but how? How?

Much later in the text.

I've done it! I found one of the patterns! Or at least I’m pretty sure I have. I need to make another trip to the western Crystal Pylon to see. If this works, the crystals I've collected should coalesce into a single mega-crystal infused with the combined powers of all the shards! I can't wait to report on the results when I get back!

Map of the pillars

Sholazar Basin pillars

This section concerns content related to Wrath of the Lich King.

Sholazar Basin

In the Sholazar Basin, there are some strange devices on top of several pillars, on these pillars grow crystals which resemble the ones in the Un'Goro Crater. Their purpose is yet unknown, but the power of the pillars is readily apparent.

List of pillars:

• Glimmering Pillar (white crystals)
• Lifeblood Pillar (red crystals, destroyed)
• Skyreach Pillar (blue crystals)
• Mosslight Pillar (green crystals)
• Suntouched Pillar (yellow crystals)

The Cult of the Damned has been shown responsible for the destruction of the Lifeblood Pillar, and is also active on top of the Glimmering Pillar.

Conservatory of Life

Conservatory of Life

There are three pylons located at the Conservatory of Life inside Ulduar, their purpose is yet unknown. It should be noted that they are unlike the pylons in the Un'Goro Crater which all share the same coloured crystal.

• 

  Yellow pylon near Elder Ironbranch.

• 

  Green pylon near Elder Stonebark.

• 

  Blue pylon near Elder Brightleaf.

Mastery of the Crystals

Container where the crystals are located.

During the quest  [20-30 Daily] Mastery of the Crystals, Lightningcaller Soo-met gets the player to use crystals to defend the gorloc faction, the Oracles. They may be in connection with the Sholazar Basin power crystals. The crystals are gotten out of a chest.

• 

   [Crystal of the Violent Storm]

• 

   [Crystal of the Frozen Grip]

• 

   [Crystal of Unstable Energy]

Notes

The ones in Sholazar Basin are also called crystal pylons.
