Arena Trap in Pokémon Black & White

Prevents the foe from fleeing.

Prevents opponents from fleeing or switching out. Eluded by Flying-types and Pokémon in the air.

While this Pokémon is in battle, opposing Pokémon cannot flee or switch out. Flying-type Pokémon and Pokémon in the air, e.g. due to Levitate or Magnet Rise, are unaffected. Pokémon with Run Away can still flee. Pokémon can still switch out with the use of a move or item. Overworld: If the lead Pokémon has this ability, the wild encounter rate is doubled.
