Weather (XC1)

Weather is a mechanic in Xenoblade Chronicles and Future Connected. White its effects are mostly cosmetic, certain enemies (most notably s) and collectables only spawn during certain weather.

Every area has a distinct set of up to three weather types that can occur with certain probabilities. Some types are story-exclusive and cannot normally occur, or can occur only during the day or night. Weather lasts for a certain amount of time and re-rolls once this expires, unless the current plot locks it to a certain state. Changing the or by reloading the area can also cause the weather to change. Travelling to a different area will keep the weather the same, if both areas share the current weather as an option.

It is also possible for battle arts to affect, or be affected by, the weather. While there are many possible ways for this to happen, in practice there are exactly two, both of them late-game foes.
 * The Sani Telethia has arts that change the current weather: Sunlight Scatter, Weather: Rain, and Weather: Storm. It is believed it also uses the current weather to pick which of its attacks to use, though this is unconfirmed.
 * True to its name, some of 's arts have an additional effect if a blizzard is happening: Rex Roar inflicts, Rex Poison deals poison twice as strong, and Rex Gore has a 25% chance to inflict Instant Death.

Weather types
While the types of weather were not given official names in the game's original release (and so have a few known more commonly by fan-names, especially those that are undescriptive), the Definitive Edition does so for most of them in the Event Theatre, where the player can set what weather is used for a scene (unless it is forced by the plot). It also includes an image with placeholder kanji that suggets the re-release was going to include weather icons on-screen, in the same vein as Xenoblade Chronicles X and Xenoblade Chronicles 2.

The Event Theatre name in this list is in bold if known, while other names seen in quest descriptions or coined by fans are in "quotes".


 * Clear - the default weather that occurs everywhere (including enclosed areas).
 * Rain - Tephra Cave, Bionis' Leg, Colony 6 (5% each), Makna Forest (7%), Fallen Arm (1%). While it's raining, the music is slightly quieter.

 * "Slumber" (, lit. "hibernation") - The original weather in the Bionis' Interior before the party enters it through Junks later in the story, which is what causes the area to be darker than its "natural" state.
 * Rising Storm or "rebirth" (, lit. "before the storm") - Used in Agniratha, Mechonis Core, and Junks during the climax of the Core.
 * An unnamed weather only used in the Future Connected version of, likely used during the final battle.
