dm: roll for perception
me and one other player: *rolls 17*
everyone else: *rolls complete shit*
dm: it looks like a normal cave. you can hear water dripping faintly in the background, but you can’t see any water. two of you detect a great sense of unease, but you can’t tell why.
me: i use my divine sense.
dm: you immediately detect a massive amorphous evil presence engulfing the entire area, it’s so powerful it’s a little dizzying. the entrance you came through is giving off powerful magical energies now. you also notice there are 10 undead figures poised with bows and arrows surrounding you on a rim near the ceiling.
me: i decide to not mention it.
