cast 'ice shield'                       cost: 35 mana
cast 'ground'                           cost: 35 mana

These three spells provide protection against various types of attacks.
Fire shield provides protection from cold and cold spells.
Ice shield provides protection from heat and fire spells.
Ground provides protection against electricity.

While alone these spells may not seem very formidable, the combination of their
effects with that of other protective equipment can make a character virtually
immune to specific damage classes.
