The DM describes the environment.
The players describe what they want to do.
The DM narrates the results of the adventurers’ actions.
That is the power of the dungeon master.
I can sneak right past security, Slip poison into the site directors coffee machine, Slip out without leaving a trace.
But what if somebody does see me?
Thats what amnestics are for.
The foundation switched to an easy, Non-anomalous easy-to-reproduce amnestic. So of course, I had to steal the recipe.

I hear a footstep around the corner. I take out my Class-F amnestic needle and clench it tightly. The leather on my gloves warm against the plastic. An armed guard walks right past me. I sneak behind and in the blink of an eye, His keycard is gone. Doesn't even notice.
Poor guy.
He's gonna get stuck in this corridor with no way out.
I walk across the corridor and into the site directors office.
Time to have some fun.
I slip a mix of amnestics and slime from SCP-999 into his coffee mug. The mix melts into the cup before you can spot it.
"Can I help you?"
