This organ continues to pulse slowly and ooze a black fluid. Researching the Psi Reaver Organ will allow you to learn how to best target the Greater Psi Reaver and its projections for maximal damage. All damage you deal to the Greater Psi Reaver and its projections will be increased by 25%. Researching the organ needs small amounts of Barium (Ba) and Radium (Ra).


This is a continuously energized sample of psycho-creative residue. It is the end product of a massively complex and focused Psionic projection. This residue can be temporarily disrupted, but not permanently destroyed, since the Psionic projection can simply be re-created by the source organism. This version of the Psi Reaver seems much more powerful than those you have previously encountered

Recommendation. While the projection can be disrupted by most conventional means, this serves as a short-term solution only. Resources should not be wasted in combating this phenomenon unless it is crucial for survival. If it must be destroyed, seek out and destroy the controlling brain structure first.


  • This is a redundant Research topic as there is only one Greater Psi Reaver in the game and you will most likely have (permanently) destroyed it before you can attempt this Research. If, however, you want to complete this Research due to completionist tendencies, be sure to bring Barium and Radium with you from the Chemical Store Room encountered earlier in the Body of the Many and a Research Implant if you haven't spent any Cyber Modules on getting 1 rank in Research. It is identical in appearance to the regular Psi Reaver organ.
