Lucas tries Defense Up.
DefenseUp (also written as "Defense Up") is a PSI ability in EarthBound Beginnings and Mother 3. In Mother 3, DefenseUp increases the Defense of a single conscious character, or all characters depending on the power level, by one-fifth of their base Defense stat on its first use, and one-tenth of the stat on its second and third uses. DefenseUp can only be used three times per battle before it becomes ineffective and fails. DefenseUp is learned in EarthBound Beginnings by Ninten, and in Mother 3 by Lucas.
