I'm on day 3 of the Die2nite beta, and I noticed that a "Betapropin tablet 5mg" has appeared in my inventory as a professional tool. The mouse-over description in the "Use an object from my rucksack" section states "this small tablet has a somewhat surprising effect..."
What does this tablet do? I'm guessing since it's a drug, it will refill my AP. What is the "surprising effect"? Does it being a professional tool make it special in any way?
