FIRE SHIELD

'FIRE SHIELD' 'ICE SHIELD
Syntax: cast 'fire shield
        cast 'ice shield

These spells create a magical shield of the specific element surrounding 
the invoker.  The shield acts as a protective barrier from the invoker's 
opponents.  If an opponent is in combat with the invoker, there is a 
chance that the shield surrounding the invoker will wound their opponent.  
Also, the shield acts as a dampening or an enhancement device against 
natural elements.  Fire attacks against an invoker while he has surrounded 
himself with a fire shield will enhance the attack whereas ice attacks 
will be dampened and be decreased in power.  The basic invoker spells
of Flame Arrow and Icicle can be further enhanced in power by the shield
of their respective elements.
