An '''additional effect''' (Japanese: '''{{tt|追加効果|ついかこうか}}''' ''additional effect''), sometimes also called an '''added effect''', is the in-battle secondary effect of a [[List of moves that do damage|damaging move]].

==Effects that affect additional effects==
==Additional effect modifiers==
There are several moves and {{Abilities}} which have effects on moves with additional effects.
{{incomplete|section|needs=Generations in which Charge Beam's effect chance can overflow}}
There are several moves and {{Abilities}}, as well as an item, which influence the additional effects of moves.
* The Ability {{a|Serene Grace}} doubles the chances of the Pokémon's own moves' additional effects occurring (up to 100%).
* The Ability {{a|Serene Grace}} doubles the chances of the Pokémon's own moves' additional effects occurring (up to 100%).
* The Ability {{a|Shield Dust}} shields the Pokémon from the additional effects of moves.
* The Ability {{a|Sheer Force}} boosts the damage of the Pokémon's own moves with additional effects, but prevents their additional effects from occurring.
* The Ability {{a|Sheer Force}} boosts the damage of the Pokémon's own moves with additional effects, but prevents their additional effects from occurring.
* The Ability {{a|Shield Dust}} prevents the Pokémon from being affected by other Pokémon's moves' additional effects.
* The rainbow created by {{m|Water Pledge}} when used in combination with {{m|Fire Pledge}} doubles the chances of additional effects occurring.
* The [[held item]] [[Covert Cloak]] prevents the Pokémon from being affected by other Pokémon's moves' additional effects.
* The [[held item]] [[Covert Cloak]] protects the holder from the additional effects of moves.
* The rainbow created by {{m|Water Pledge}} when used in combination with {{m|Fire Pledge}} doubles the chances of additional effects.


The effects of the rainbow and Serene Grace stack, except for chances to [[flinch]] (which can only be doubled once), meaning that when used together they quadruple the chance of additional effects. Internally, the chance of an additional effect is stored in a byte; as such, in Generations V to VIII, if the chance of an additional effect is increased past 255 by a combination of Serene Grace and the rainbow effect, it will overflow and wrap back around from 0. This only matters for Charge Beam, whose 70% chance would become 280%, thus causing it to overflow to 24%, as moves with 100% effect chance which overflow back to 100%.
