Dungeons and Dragons

I have at least once. I just started running PF2e fairly recently but there is a complex hazard in the beginner box adventure. It's like a room with a statue that activates when players step on a pressure pad in the room. The statue does a random thing on each of its turns, either attacking a single random creature in the room, attacking all of the creatures on one side of the room (left or right), or attacking every creature in the room. The statue can be disabled by disarming clockwork mechanisms at its base (or by smashing it), and the damage it can do is about 2/3 of a PC's HP in that adventure (note that PF2e kinda assumes PCs go into every encounter fresh; there's lots of out-of-combat healing).

When I ran this encounter recently, the PCs played it in a very interesting way, and it felt a lot more like a combat. They tried different approaches, and eventually figured out how the statue worked enough to circumvent it. But during those first couple rounds where they didn't know what was going on, they had to frantically try things while the statue threatened to kill one of them every time its turn rolled around. They knew they could leave the room at any time, but they also knew that if they could survive one extra turn then it would mean a little bit more time to disarm the statue. It made for a very tense and exciting encounter.
