>>386206For Shadow of Chernobyl, it grants +5 Bulletproofing at the cost of +5 Radiation.
In Clear Sky, it raises carrying capacity by 10 kg at the cost of +1 Radiation.
In Call of Pripyat, it grants a +4 kg to carrying capacity at the cost of +1 Radiation.
Also, between ShoC and Clear Sky it had a model change, and became a glowing, many-quilled sphere.
This wonderful artifact is formed by the Springboard anomaly. The use of the artifact demands the neutralization of deadly radiation. Expensive and rare, this artifact is extremely interesting for scientific expeditions and other research activity in the Zone.
Acquisition
This is a rare artifact. It is possible to find at least one of these artifacts on the edges of Agroprom, however these areas have very high radiation levels. Baldy will reward the player with this artifact after completing his mission Kill the traitor. Several Night Stars can be found near the Monolith "sculpture" in Pripyat, and more can be found at the Chernobyl NPP.
Pricing
The Night Star can be sold for a disappointing 3250 Ru (Sakharov gives 5000 Ru).
Hope this helps. Pic related, ShoC inventory icon for the Night Star artifact.
