[Spells help] spirit aura

Syntax: cast 'spirit aura'

Spirit aura calls forth the spirits of a shaman's ancestors, who come
forth and surround him in a protective manner.  If a foe should approach
to melee with the shaman, the spirits will cry down curses which plague
the foe's attack and causes some of the damage to rebound on the attacker.
