Slayer of Champions

(Rule)
Description: Before resolving any combats in any Assault phase where the Emperor's Champion is in combat with an enemy unit containing one or more enemy Independent Characters, you must immediately move the Emperor's Champion so that he is in base-to-base contact with at least one enemy Independent Character (maintaining coherency with any units he has joined). If there is no room to place the Emperor's Champion in base-to-base contact, simply move a friendly model out of the way (he makes room for the Emperor's Champion to get to grips with his foe!).
