Klyonov's artifacts

Marked One decides to check on Klyonov in Warlab; he must have transmuted the artificial Poltergeist's Heart you gave him earlier in Artifacts for Klyonov.
==Walkthrough==
Klyonov informs you that the experiment was a failure, and the Poltergeist's Heart has been changed. However, he's preserved its core in a similar, less radioactive artifact. Another interesting artifact, named Spiral was created in the process. Take both of them for now.
==Notes==
* Depending on your artifact loadout and difficulty setting, the Spiral may be useful due to its 7% bulletproofing that can be used in conjunction with a Burer's Great Grandma's Beads (13%) to get to an even multiple of 10.
