You know danger is lurking, hidden, somewhere in these ruins. The corridor looks suspiciously inviting, cleared: no moss, no vines, no debris of any kind. Your gut is telling you, and you listen. With a subtle hand gesture with your fingers, and a whisper of the esoteric, you cast your Find Traps spell. Your vision magically blurs for a moment. You feel the presence of danger. Uncertain of its location but deducing that the nature of the pain is piercing, it might be spikes waiting for you, should you walk on a weakened floor, or shuffle the trigger of a dart…those small holes up above, just ten feet away, might be the clue.
