Ethereal

Models with this special rule treat all Terrain as Open Terrain for movement purposes, but cannot end their
movement inside (or within 1" of) Impassable Terrain. Model parts with Ethereal gain Magical Attacks, and
non-mount model parts with Ethereal gain Ward Save (5+), which is increased to Ward Save (3+) against all attacks that are not Magical Attacks. Units including any non-mount R&F part with Ethereal can only be joined by Characters with Ethereal on a non-mount part.
