Heatsense An immolis can sense creatures whose bodies are hotter than their surroundings as a precise sense at the listed range. Creatures that produce no heat—such as many undead or constructs—are concealed to an immolis, as are creatures who successfully mask their body heat (such as by submerging themselves in cold water).
