A nine-second potion that lets Carl pass through artificial nonliving solids but can drop or bisect him when its counterintuitive rules end.
The potion phases its user through any solid, artificial, non-biological barrier with empty space on both sides. Natural cracked pavement remains solid, while floors, walls, and vehicles may cease to support the user.
A second-story user can fall through successive artificial floors until reaching natural ground or another living body. If the effect ends while the user intersects a solid, the result may be catastrophic.
Carl owns ten after repeated box rewards. Each dose lasts nine seconds, and its cooldown is exactly one second longer than duration, preventing seamless chaining.
During Raul's capture, Carl crosses the tailgate, cargo walls, floor, and ceiling plane to attack from impossible angles. He drinks two doses and twice finishes pressed beneath the truck, narrowly avoiding being cut apart.
A potion vial containing translucent silver liquid, with a human silhouette passing halfway through a wall.
The potion provides extraordinary infiltration and evasion at a severe geometric risk.
