Very rarely found artifact, located near the Whirligig anomaly. Only a very few manage to find this artifact, and few have even seen it. It has a nice shape and an equally nice price. - In-game description
The Soul increases health regeneration by a heavy +600%, allowing the player to easily recover health, especially when the player combines this with suits like the Ghost suit. However, the Soul decreases overall hit protection by 10%, which can be countered by heavy suits and is more or less negated by the higher health regeneration.
A unique organic artifact with properties just as unique. Somehow it increases the body's overall recovery rate. Thanks to its reasonable price and an attractive appearance, this artifact is a valuable collector's item. Emits radiation. - In-game description
The Soul returns in S.T.A.L.K.E.R.: Clear Sky as a common artifact that increases health regeneration by a light +2, but radiation by +2 as well. The granted bonus is nearly insignificant, making the artifact better traded than used.
A unique organic artifact with properties just as unique. Somehow it increases the body's overall recovery rate from damage of any kind, without accelerating the accumulation of toxins. Thanks to its effects and attractive appearance, this artifact is a valuable collector's item. Emits radiation. - In-game description
The Soul may be found in chemical anomaly fields; the Quarry and Concrete Bath anomalies in Yanov spawns one by default. The Soul is part of Snag's loot in the Unreachable Stash and can be obtained by either having Cardan open the box or give Snag the box and ask to take the Soul - if Snag kept the Soul for himself the player will have a second opportunity to obtain it during the Theft mission, in Snag's stash.
