View source for Acid rain

'''Acid rain''' is a glitch in {{game|Platinum}}, {{2v2|HeartGold|SoulSilver}} that results in the simultaneous occurrence of all [[weather conditions]] at once, thus damaging all Pokémon on the field. Even though it was discovered before the English release of Platinum, it is still in all versions of the mentioned games.
 
==Cause==
If any weather effect (including Trick Room, Gravity, and Uproar, but excluding rain) is in effect, if a player of Platinum/HeartGold/SoulSilver uses {{m|Pursuit}} on a Pokémon that is switching out on that turn and causes it to faint, the glitch will activate. Upon sending out the next Pokémon, the weather will have changed, and all four weather conditions will be going on at once until the end of the battle.

This will occur if the user of Pursuit is the host, even if the host is [[Pokémon Diamond and Pearl Versions|Diamond or Pearl]].

==Effects==
If {{m|Trick Room}}, {{m|Gravity}}, or {{m|Uproar}} is in effect when the glitch is activated, they will activate the glitch, along with any other effects with priority below it. The priority is:
# Trick Room
# Gravity
# Uproar
# Fog (hurts after animation)
# Hail (hurts after animation)
# Sunshine (hurts after animation)
# Sandstorm (hurts after animation)
# Rain (Hurts after animation. Glitch cannot be activated using this weather)

Other moves with multiple-turn effects such as {{m|Mud Sport}}, {{m|Water Sport}}, {{m|Tailwind}}, and {{m|Perish Song}} will not be affected and work as normal.

Even if the Pokémon is normally immune to a weather condition due to its type ({{type2|Ice}}s with hail and {{t|Rock}}-, {{t|Ground}}-, and {{type2|Steel}}s with a sandstorm), they will accumulate damage '''four times''' each turn, with the cause of the damage identified as their [[ability]], rather than the weather. In this way, a {{p|Pikachu}} in battle can be hurt by its {{a|Static}}, or a {{p|Buizel}} by its {{a|Swift Swim}}.

However, if the Pokémon is immune to both {{m|Hail}} and {{m|Sandstorm}}, like {{p|Swinub}}, that Pokémon will be immune to all of the damaging effects of this glitch.

Conversely, a Pokémon with an ability that heals it in certain weather conditions, such as {{a|Ice Body}} or {{a|Rain Dish}}, will not take damage, but instead be healed four times a turn until they are fully healed, then the weather will hurt it. An ability that heals in some weather and hurts in other weather will work as it normally does, healing with one condition and hurting with the other.

Both {{m|Thunder}} and {{m|Blizzard}} have 100% accuracy, due to simultaneous rain and hail, while {{m|SolarBeam}} requires no charging due to the sun. 

If a {{p|Castform}} or {{p|Cherrim}} is brought into battle, their ability will cause them to constantly transform, thus locking up the battle until the game is turned off. Castform, will only transform between its [[Form differences#Castform|Sun and Rain forms]] due to those particular weather conditions being the first two to occur (and thus, Castform recognize these as being the only two weather conditions on the field).
