At the start of each Close Combat phase, choose an enemy model in base contact with the Changeling. The Changeling may increase any or all of his Weapon Skill, Strength, Toughness, Initiative and Attacks characteristics to match those of the chosen enemy model until the end of that phase. If the chosen model has more than one value for a characteristic (as is the case with a mounted model), the Changeling may always choose the higher value. The Changeling cannot match the characteristics of an enemy that is fighting in a challenge, unless the Changeling is fighting in the same challenge.
