Spark Shield is an Evocation spell that can be cast by Clerics, Sorcerers, and Wizards. This spell creates an aura of electricity around the caster that causes attackers to take damage when they attack the caster. For wizards and sorcerers to cast the spell they need to know the appropriate words, gestures, and use two thin copper bracelets. A cleric may cast the spell by knowing the appropriate words, gestures, and using their holy item.
