|The user weaves a sticky net around the opposing team, which lowers their Speed stat upon switching into battle.|
Sticky Web sets an entry hazard around the opposing Pokémon, which lowers their Speed stat by one stage upon switching in. It doesn't affect Flying-type Pokémon, Pokémon with the Levitate Ability, or Pokémon holding an Air Balloon.
Pokémon with the Ability Clear Body and White Smoke will not have their Speed lowered, and Pokémon with the Ability Contrary will instead have their Speed raised by one stage. Sticky Web triggers the effects of the Abilities Defiant and Competitive.
The moves Rapid Spin and Defog remove the effect of Sticky Web; Rapid Spin removes Sticky Web set around the user, while Defog removes Sticky Web set on both sides.
