Chaos Stone is an item found in the Mass for the Dead.


After the Catastrophe that engulfed the New World, which resulted in the near destruction of all the kingdoms, several of these strange stones began to appear. Additionally, these are item drops that appear after a Chaos Beast is defeated.

In the game, Chaos Stones have many uses, such as limited-time summons, chaos summons, health recovery, quest maintenance, etc. For example, using 15 chaos stones, a player can restore stamina in a quest. Chaos stones can also be used as a means of resurrection when a party is annihilated in a quest.

There are two types of chaos stones: free ones that can be obtained without charge and paid ones that can be obtained with charge.

Through the research of Sophie Noia, she found that Chaos Stones could be used to enhance items that make them resistant to the corrupting effect of the "chaos environment". Her application though a major breakthrough was similar in regards to players embedding data crystals to items to enhance them. The technique was taken by the Sorcerer Kingdom and used to create adaptive equipment.[2]

Another characteristic Chaos Stones have are being used to open portals to other worlds in conjunction to a Crack. However a great deal of stones are required, just as much as summoning, and they need to be placed close to the aperture when the Crack activates and simultaneously a magic caster needs to activate spatial magic to achieve the feat.[3]
