"…I will carefully consider it." Jin smiled at the foreign girl and thanked her for her patronage. The other three Fire Shamans also gave their praise to Jin, especially Jasmin who suffered the most in the fight as she hadn't been prepared for it being so intensely real.
"If I didn't know that it was just a dungeon instance, it might seriously have given me PTSD," Jasmin mentioned in a casual way, but Jin knew that the System had been ensuring that such symptoms were being sniffed out from their memories.
Apparently, Pei and the System (with a little tinkering from Kraft) had come out with a sort of spell that would purposely manipulate the memories of the user.
Because the experience the customers received was undoubtedly real, it was necessary for there to be such a filter to prevent the customers from developing possible symptoms of PTSD, anxiety or other traumas from merely playing dungeons.
