Warrensense

Choose a humanoid subtype or a specific type of creature (like manticore, red dragon, or skeleton). For the duration you can see footprints created by those creatures in the last 24 hours. The footprints create a light glow that only you can see, allowing you to see the footprints in darkness without actually illuminating the area.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, you can choose an additional humanoid subtype or specific type of creature for each slot level above 1st.
