Dualithnode Crystal

The Dualithnode Crystals (デュアリスノ結晶, dyuarisuno kesshou^?, lit. "Dualissno Crystal") are synthetic high-grade versions of the Grathnode Crystals, which are found only in the region of Metafalss. The Dualithnode Crystals serve as the core for one of the main gameplay systems used in Ar tonelico II: Melody of Metafalica: the Reyvateil-exclusive level up system known as Dualstall.

Definition

Not much information is known about the Dualithnode Crystals beyond the fact that they were invented by the Grand Bell centuries prior to the start of Ar tonelico II: Melody of Metafalica as a way to substitute the Installs due to the fact that Grathnode Crystals are rare and difficult to find in Metafalss, as well as the Installs being too much of a painful procedure for the Reyvateils, given the great respect the people of Metafalss hold for them.

This led them to invent the strengthening method known as Dualstall, which allows the Reyvateils to gain power in a relaxing and painless manner. This is due to the fact that the Dualithnode Crystals make practical use of a property they share with the Grathnode Crystals, which is that once they have surpassed a fixed quantity of wave flow, the energy contained in the waves can be naturally diffused into liquids. This allows the energy and powers contained in the Dualithnode Crystals to be transferred to the Reyvateils via osmosis through mere contact with the liquid where the crystals are submerged, without needing to directly place the crystal upon the Install Port.

However, this has a downside in that the crystals containing the most potent waves can distort the D-Waves that make up the Reyvateil's body, possibly killing her in a phenomenon that is known as hyper-effect. The only way to prevent this is to have the Reyvateil perform a Dualstall with fewer crystals, in a larger bathtub, or bathe alongside other Reyvateils, so the waves emitted by the crystals are split between all the people involved in the process.

In Gameplay

Dualithnode Crystals are one of the main item types found in Ar tonelico II: Melody of Metafalica, so they can be either won as spoils from boss battles, bought from shops, or found in chests strewn throughout Metafalss, with the strongest crystals having the particularity that they appear in some of the earliest areas in the game late in the story and that they are also guarded by Lv. 9 IPDs. The second crystal gotten in the game is also gotten from a story cutscene, though it is the only crystal obtained in this manner.

Trivia

The names of the Dualithnode Crystals are all composed of a set of words in Japanese/English (depending on the game's language version) and a series of Hymmnos glyphs that can range from one to three letters. This is due to the fact that the names are actually written in Carmena Foreluna, with the original name being the series of Hymmnos glyphs and the name in Japanese/English being a translation of them. This made them the earliest piece of information regarding Carmena Foreluna that was available to the Ar tonelico series players and fans.
