When a Pokemon with Desolate Land enters the battle or a Pokemon gains the Ability Desolate Land, the Ability creates extremely harsh sunlight, a unique variation of intense sunlight. The extremely harsh sunlight lasts as long as the Pokemon with Desolate Land is in battle. In aRotation Battle, Desolate Land will not activate if the Pokemon is sent out in a rotated-out position and will not activate if the Pokemon is rotated in; extremely harsh sunlight will dissipate if the Pokemon is rotated out.
Along with the usual effects of intense sunlight, extremely harsh sunlight causes damage-dealing type moves to fail. Additionally, extremely harsh sunlight causes the weather modifying moves Sunny Day, Rain Dance, Hail and Sandstorm to fail if used; and it causes the AbilitiesDrought, Drizzle, Sand Stream and Snow Warning to fail to activate.
If Desolate Land is suppressed or replaced, the extremely harsh sunlight it causes will disappear. If another Pokemon in battle has the AbilityPrimordial Sea or Delta Stream, the dominant weather conditions will be determined by whichever Ability activated last.
