'WRAITHFORM' (523)

Syntax: cast 'wraithform'

This spell allows the caster to step partially into the Ethereal Plane.  While
affected, the caster may pass through closed doors and is somewhat protected
from weapons in the Prime Material Plane.  When a necromancer becomes more
powerful and reaches the 36th rank they learn how to use this spell to pull
themselves into the Ethereal Plane long enough to avoid a bash.  Necromancers
who have Become (Liches, Mummies, etc.) additionally possess the ability to
levitate in this form.
