[Lock's Homemade Revolver]: This is a homemade revolver crafted by a cowboy named Lock.
Effect: A Level 6 Item, by opening the safety catch and pulling the trigger, it can fire a bullet that ignores ghosts and spectres of Level 7 and below. Creatures of Level 5 and below that are hit will surely die. A hit to a critical spot on a Level 6 can cause serious injury or even death, and can harm Level 7 creatures, though most damage is mitigated on those above Level 7.
Remaining bullets: 1
Note: After the bullets are used up, please find Lock to purchase specialized bullets.
Indeed, it's an extremely powerful item, capable of ignoring ghosts and spectres, and when used in conjunction with Mu Rufeng's sandbag, it's simply a perfect match.
After pinning down an enemy with a sandbag, those of Level 5 and below are certain to die. As for Level 6, with good marksmanship, critical spots can be targeted for a kill.
