Click on the Beholder to "roll" your d20 and see if you can get a critical hit for 2x damage -- before its hit points reach 0. This is a work in progress (see below).
For such a simple prompt, this one really challenged me. Since I didn't know where to start, I approached this the same way when working with other material, and just started "doing stuff." Once I put a few blocks together, this idea came together. Right now, there's no real end to the game and I'm open to suggestions. I'm struggling with having the scripts stop when Hit Points equal zero or less. I've tried a lot of variations with the "stop all" block, and haven't had any success - will try again soon.
