Similarly, it’s a bit broken that you see the perception check failed notifications. Like, ok, I don’t know what is there, but I know something is there. In real life I’d have no idea and I’d go on about my day.
In 5th edition you are not supposed to know; this is what the Passive Perception score is for. If you’re not specifically looking for anything, the DM is supposed to use your Passive Perception instead of rolling a check that would alert you to the existence of something hidden; if you are specifically looking, you roll Perception whether or not there is anything to find.
Yeah, and if you didn’t see the failures, you wouldn’t be tempted to save scum. I can see why they’d leave the notifications in by default; there’s potentially a ton of content locked behind these kinds of checks. But I’d appreciate the option to turn them off.
