**Caution Contains Spoilers**
Whilst GMing my group of Acolytes through the events of Rejoice For You Are True the Cell’s Psyker picked up an addiction to Farcosia, which isn’t too bad until you realise that the narcotic is made up from distilled psyker brains (if I can remember correctly). The Psyker in question managed to fail all tests relating to the drug, including multiple attempts at discovering its warp signature (I made him roll these whenever he got close to the Tech-priest, who was carrying a sample of the drug around with him). When the substances true nature was revealed he managed to keep his cool however, and even expressed an interest in taking several of the samples found in the temple with him for “ further investigation ”.
My question to you is what effect do you think this should have on him? The book seems to suggest that normal Psykers wouldn’t even want to be in the same room as a Farcosia sample, let alone drink it. Should I give him insanity or corruption, or maybe even both, for willingly taking it? Do you think he would have a change of being able to track down any more of the stuff, and if so what would the cost be for such an item?
Any ideas on this subject would be much appreciated.
