This article is not to be confused with "PSI Shield."

Shield is a PSI ability in EarthBound and Mother 3. It protects a single conscious character, or all characters, with a 50% reduction of enemy attacks, and even returns some of the blocked damage to the attacker, depending on the power level. Shield is realized in EarthBound by Ness, Paula, and Poo, and in Mother 3 by Lucas.
