The Defending PokÃ©mon can't retreat as long as Murkrow remains your Active PokÃ©mon. (Benching or evolving either PokÃ©mon ends this effect.)
Choose 1 of your opponent's PokÃ©mon. This attack does 20 damage to that PokÃ©mon. This attack's damage isn't affected by Weakness, Resistance, PokÃ©mon Powers, or any other effects on the Defending PokÃ©mon.
