A compound of several hollow organic formations, this artifact emits a gaseous substance that can neutralize radioactive particles inside the body. This artifact is extremely valuable.In-game description
The Bubble reduces radiation by a heavy -6, making the use on anti-rads nearly redundant as the Bubble can clean existing radiation quite quickly, especially when combined.
The Bubble artifact can be received as part of a reward after joining the Loners and eliminating the Bandits at their main base in the Garbage. The Bubble is also located in a stash (Crate with backpack) in the Red Forest, the coordinates can be found after surviving the ambush and interrogating one of the survivors. It has a chance of spawning in several anomalous fields throughout the game, including the swamp in Yantar (unlikely), underground section of the Red Forest (likely), and the marshes in the Army Warehouses (very likely).
Call of Pripyat
A compound of several hollow organic formations, this artifact emits a gaseous substance that can neutralize radioactive particles inside the body without harming it. Because of its effectiveness, this artifact is in great demand.In-game description
The Bubble returns in Call of Pripyat, its radiation effect having been reduced to a small -4, making it less useful but still very useful to counter radiation. It is also part of Beard's artifacts orders.
The Bubble may be found in chemical anomaly fields; the Department Store in Pripyat spawns one by default. The Anomalous Grove in Yanov, however, has very low chances to spawn the Bubble itself due to the few amounts of anomalies - the player should complete the Anomalous Plant mission for Ozersky first and the Bubble will more likely to spawn there due to the increased number of anomalies.
