'crystal shield' allows the caster to create a large but light shield made
of crystal, suitable for a mage to use (or more likely hide behind.)

Crystal shields can also take on stronger elemental defenses if the caster
has knowledge of fire, ice and lightning defensive spells.  For example,
to create a shield with a strength against fire, use:
