[Spells help] sanctuary
Syntax: cast 'sanctuary' 
Sanctuary is a very powerful defensive spell, similar to protection.  With
it, the caster calls forth a blessing that erects a strong barrier around
someone.  This barrier is so formidable that it is impossible to even attack
the person so protected, unless one resists the influence of the barrier.
Even if one is able to resist, the force still absorbs a great deal of the
damage dealt, providing an effective defense.  However, this blessing is
only granted for defense and will disappear as soon as one tries to strike
another without first being attacked.
