This spell enables the caster to become one with nature, thus being empowered with knowledge of the surrounding territory. For each level of experience of the caster, he can "know" one fact—ahead, left, or right, about the following subjects: the ground, plants, minerals, bodies of water, people, general animal population, presence of woodland creatures, etc. The presence of powerful unnatural creatures also can be detected, as can the general state of the natural setting. The spell is most effective in outdoor settings, operating in a radius of one-half mile for each level of the caster. In natural underground settings—caves, cavern, etc.--the range is limited to 10 yards per caster level. In constructed settings (dungeons and towns), the spell will not function. The DM may limit the casting of this spell to once per month.
