The lucky abyssal whip retains abyssal whip's special attack, Energy Drain, which requires 50% adrenaline. This deals 100% weapon damage and steals all of the opponent's run energy.
There was a bug where players could make tradeable abyssal whips by using the whip vine on the lucky abyssal whip. This would turn the lucky whip into a standard abyssal vine whip, after which separating the item would return the whip vine and a standard abyssal whip. The lucky abyssal whip could then be reclaimed from Diango (or Ianto) and repeated again. This bug has since been fixed.
