Effect
A Pokémon with this Ability will copy an Ability of an opponent that uses a move on it and will last until it transitions to a new floor or area.

This will not take effect on Abilities that changes forms or Abilities, this means that Trace will not work on: Likewise, Trace cannot be copied by Role Play, Power of Alchemy, or Receiver. Entrainment will always fail if the target has this Ability.
