you have them roll for perception first then you are narrating the area and having players say what they want to do afterwards
now their actions are going to be influenced by their low perception roll
You shouldn’t be rolling for perception first. Players don’t get to roll until they actually do a thing, until then you use passive perception. And even if you are rolling a perception check on their behalf, you do it behind the screen. So they won’t know if they rolled well or not.
rolls come after the declaration of actions
Hard agree! But passive perception isn’t an action or a roll. It’s passive.
The thing about BAD traps versus a GOOD traps, though, is ensuring that players have the opportunity to try avoiding it.
Exactly. The players should have the opportunity to avoid it. If traps are only a binary - perfectly obvious or completely invisible depending on a single roll - then the characters had a chance to avoid the trap, but the player didn’t. And then “optimal play” is painstakingly triple-searching every square foot of the dungeon in case Schodinger’s Trap is lurking somewhere.
Which is either trivial and tedious (in games where you don’t track the passage of time) or stupidly punishing and tedious (if you are tracking time). Since I do prefer to track time spent, I’d rather give my players the sense that they can ‘logic out’ where traps are likely to be and encourage them to spend their valuable time searching only when and where it makes the most sense. After all, skill expression is a very rewarding part of playing a game. And being able to predict where a trap is likely to be and then finding one there? That really makes players feel like adventurers.
