done by going to Sheridan's Mansion and selecting 'Change Climate' to change the default weather. Certain parts of dungeons, which often hold new items and weapons, are inaccessible unless the player changes the weather. Special high-priced items are dropped by enemies or objects under certain climate conditions. The game relies on an in-game weather control system, known as the paraSOL. It has a thermometer, and measures humidity and wind speed. The weather is generated from the game itself, not from the local outside environment. There are five types of weather: balmy subtropical, tropical rainforest, humid continental, arid desert and frigid arctic. The Trance meter is built up as the player lands blows on their enemies. When it is full, the player can use the powers of one of their Terrennials to launch into an extra powerful attack that affects multiple enemies. The transformations mentioned above are two of these attacks, but some are more magical in orientation, and often revolve around interaction with the touch screen. Burst attacks are Trance moves performed by terrennials other than Toasty and Nero. When a Burst attack is used, the weather will change accordingly. Terrennials are the physical manefestiations of the elements that accompany the characters, with fire, ice, wind, and earth represented. In addition, the sun has a terrennial as does darkness. Furthermore, there is a null-elemental Terrenial only available in the Japanese version - War Rock, whose details are described below in the Crossover section. When these terrennials are equipped, the player can use TRC powers, and they will add their elemental attacks to weapon strikes, at the cost of some energy. Each element is directly vulnerable to its polar opposite, and resistant to itself. For example, if the player strikes an ice-aligned monster with fire equipped, extra damage will be dealt, but if ice is equipped, less than normal damage will be dealt. W-Gate slot The player is able to use the Game Boy Advance Boktai games' sun sensor to play Lunar Knights like the original Boktai games. This option gives the player more of an advantage: slotting a GBA game into the DS' W-Gate allows the player to use extra sunlight by adding the detected sun strength to the amount produced by the in-game weather system (the extra sunlight appear as green blocks in the game's sensor bar) for a certain amount of time. It also enables the player to
