How it works in Champions

Sets up a hazard on the opposing side of the field, damaging each opposing Pokémon that switches in. Fails if the effect is already active on the opposing side. Foes lose 1/32, 1/16, 1/8, 1/4, or 1/2 of their maximum HP, rounded down, based on their weakness to the Rock type; 0.25×, 0.5×, neutral, 2×, or 4×, respectively. Can be removed from the opposing side if any Pokémon uses Tidy Up, or if any opposing Pokémon uses Mortal Spin, Rapid Spin, or Defog successfully, or is hit by Defog.

“The user lays a trap of levitating stones around the opposing team. The trap damages opposing Pokémon that switch into battle.”
