Wrench Lurker is a Gene Tonic which quiets the user's footsteps and increases Wrench damage against unaware or shocked opponents.
Either version will make the user's footsteps completely silent, allowing players to sneak up on unsuspecting splicers even at full speed. Both versions of this Tonic can be equipped at the same time for an increased damage effect.
Enemies rushing/attacking a decoy from the plasmid Target Dummy count as unaware.
When fighting those stronger or faster than yourself, you'll need every advantage possible in a scrum. Wrench Lurker allows you to make the most of your opportunities when your antagonist is caught off guard.
Increases Wrench damage by 150% against unaware or shocked opponents and quiets the user's footsteps.
