The caster can use this spell to enter an ethereal state. Once ethereal, the caster cannot use magic, Meditation skill, attack in combat, or use missile weapons, but may, however, move through solid objects (such as walls) and cross obstacles or difficult ground, including water, without penalty. An ethereal character can also become visible or invisible at will.
Characters may remain ethereal for as long as they like. Clothing and immediate possessions all become ethereal, but not other creatures - including those touched or mice secreted in pockets!
