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 WS, S, T, I and A 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.
