This runner is found outside the zone barrier, so cannot be physically reached. Instead, go directly behind the entry portal and stand in the break between the logs, facing the barrier. Further ahead you'll see a log with a clump of ferns at its right-hand end. Place a freezing trap just in front of the ferns. Every couple of minutes some Ephemeral Runners will run past and with good placement you'll trap one and can tame it. Invasion Point: Bonich may be reached through a portal in northern Antoran Wastes, Argus.
Level scaling: Most NPCs will scale with the Hunter's level, within the constraints of their level range. Hunters can tame regular NPCs up to 2 levels higher than them, but can only tame elite NPCs of the hunter's level or below.
