Most druids step lightly through nature, wishing to cause the least impact on the environment, gaining a wraith-like ability to disappear from trackers’ perception as a result. Some are not so cautious, believing their footprints to be part of natural order. However, they can still dissuade trackers by spryly choosing paths along exposed roots, low branches, jagged rocks, or subtle dunes.
Beginning at 3rd level, a druid traveling through natural terrain is difficult to pursue. Anyone tracking the druid treats his trail as difficult terrain. Additionally, as a swift action, a druid can designate a number (up to his Wisdom modifier) of 5-foot areas he passes through as traps. Anyone other than the druid entering such a space must make a Reflex save (Dc 10 + the druid’s level + Wisdom modifier) or fall prone. The druid is not actually setting traps, but merely noticing natural pitfalls along his way that he veers trackers toward.
This ability replaces trackless step.
