Maybe some sort of hallucinogen is what I'm thinking; whoever gets inflicted sees a particular figure (scary Grimm, mystery monster, personal fear, etc.) and its not really there of course. Strategically the wielder of said drug may use it to alter their victim's senses.

Vision is a common one: just seeing random things that aren't there (Shani getting followed by some mysterious Grimm that's immune to her attacks), or you have one opponent, and suddenly they've split into 6 different copies (Shani thinking the agent has a cloning Semblance, but her actual Semblance could be something else).

And of course, the effects are in the experimental stage still, so they would only be temporary. Maybe drug lasts only 5-10 minutes, splashing water in victims face would flush it out, or whichever to name a few possibilities.
