Shadow of Chernobyl
Crystallizes in the anomaly Burner. Fights well with radioactivity, though the heightened rate of energy exchange wears out the muscles of the moving apparatus. Won't be able to run for long. Artifact emits heat.In-game description
The Fireball reduces irradiation by 20%, but reduces endurance as well by 18%. The Fireball could help the player in the early game to purge small amounts of radiation, although the Crystal reduces irradiation by 30%, making it a better choice as soon as found.
The Fireball is an uncommon artifact that can be found in the Agroprom Underground inside the hideout containing Strelok's stash. The Fireball is normally placed in the open on top of some equipment just to the left of the player as the room is first entered; due to a spawn bug, the Fireball could appear inside the equipment, making it impossible to obtain. The player may encounter them at Wild Territory and in most Burner anomalies, Lab X-18 and Lab X-16. It can be found in the following stashes: Agrosafe in Agroprom, inside Rotted stump at Garbage, in the Switchboard with a secret stash in the Bar area of Rostok and in a Secret stash in Wild Territory.
Even though Fireball is a thermal artifact, it can be handled without fear of being burned. This artifact is valued for its ability to maintain a temperature of 75 degrees within a small radius, virtually regardless of its surroundings. Emits radiation.In-game description
The Fireball returns in S.T.A.L.K.E.R.: Clear Sky as an uncommon artifact that provides a +3 in fire protection but +1 in radiation. The player could combine multiple Fireballs as well as an anti-radiation artifact to get good protection against thermal anomalies.
Call of Pripyat
Even though Fireball is a thermal artifact, it can be handled without fear of being burned. This artifact is valued for its ability to maintain a temperature of 75 degrees Fahrenheit within a small radius, virtually regardless of its surroundings. Emits radiation.In-game description
The Fireball in S.T.A.L.K.E.R.: Call of Pripyat remains an uncommon artifact as with its Clear Sky rendition, but gives a +6 in fire protection and a +2 radiation. By combining two of these, the player could get a heavy +12 in fire protection, although this would require a Bubble or two Jellyfishes to counter the radiation effect.
The Fireball can be found in thermal/fire anomaly fields; the Circus anomaly in Zaton spawns one by default.
The Fireball is a possible reward from Petruha after the player rescues him from the Boiler anomaly. In order to get this artifact from him, the player must have a Bear, Veles or Svarog detector. He will then give the player the Fireball once he steps back from the anomaly. If the player has no detector or the starting Echo detector, he will give the player his own Bear detector, although one can still buy the Fireball from Petruha.
